I've been using the Rokinon 135mm F/2.0 ED UMC lens for astrophotography in the backyard for the past week or so, and I now see why it's such a popular camera lens in the community.
My favorite aspect of the Rokinon 135mm F/2 is the mid-range focal length, which creates some incredible framing opportunities for large deep sky objects, or multiple targets at once.
The focusing adjustment ring has great tension, which helps when using live-view on your DSLR camera to focus a star. For the best results, most amateur astrophotographers recommend shooting at F/4 with this lens.

Thanks for the shout-out! This small lens with an EQ mount is as close to frustration-free astrophotography as you can get. I just carry the whole rig outside, polar align, and start imaging in 10 minutes.
Frustration free astrophotography! Ahh I like the sound of that :) Thanks again for letting me share your images, Eric. Keep up the great work man. 🤠
@@AstroBackyard Hi Trevor
Love your videos. I have a Canon 700D(T5i), 135mm Rokinon F2 Lens, Astronomik 12nm ha Filter, all mounted on top of my Celestron AVX mount. I'm going to pick up a 600D (T3i) and was wondering the benifits of removing the IR Filter from the sensor..? This is entire reason i am getting a second camera(to modify it for astrophotograpy)..
Are the results worth the effort...? i really hope so :)
I've been super impressed with my copy of this lens. Just enough reach to capture detail but wide enough to give context, and sharper than it should be at its price point. It's a great astro lens.
7:50 Tip: you can activate an all-sky survey by going to 'sky and viewing options' -> 'Surveys' and then activate any of the 'DSS' surveys by selecting them and pressing 'ctrl + alt + D' to turn the surveys on. Its a super deep photographic survey with many faint nebulae also!
I just bought the Rokinon 12mm f2.0. Amazing for night skies
Was just looking at purchasing this lens, amazing images you got there Trevor.
Clear skies
Thank you!
Nice to see you're using this little gem, Trevor!
Tip: you can use the tripod collar of the William Optics Zenithstar 61 with the Rokinon/Samyang 135mm. Just mount it between the focus and aperture rings, and it really improves the balance!
This is why I love the comments. Brilliant! I will do this! Thanks
Are you sure the collar from Z61 is a fit? Not to small or not too big?
Boy I hope you are right, I ordered a collar from WO that goes with their Z61.
@@triangulumpubg6295 Did it work out?
@@XanderMarjoram yup!
The widefield lagoon nebula shot looks amazing, a lot of detail.
Thanks Isaac - it's an amazing area of sky. I'd like to try it again under dark skies!
Best lens I've ever got. In combination with Canon 6D it's killer combo.
Did you modify the 6D? I got 3 retired ones from work. I might switch one to IR. Didnt know if there is another go to option since I have them.
@@conklin29579 go for a partial defiltering, it's better than full IR for astrophotography
Wow, Great video!
I love how the triffid and lagoon image turned out
Thank you! Perhaps a little muddy - but I still geek out seeing all of the DSO's in the area! :)
Learned and inspired! Every second and every word of this video is invaluable. I own Rokinon 135mm, but learned a ton more. Good job Trevor!
Thanks very much, Ray!
Just a quick comment regarding the lens hood comment you made. The lens hood generally is only useful when there is ambient light that can enter the lens from weird angles. Looking into a night sky, where there are no streetlights or other point lights near or in the frame, the hood really isn't needed. Therefore, for most astrophotography, the hood can be removed. By the way...loved the video about "why I do it". I hope everyone got the bigger message that your philosophy applies to anyone's hobby.
I also use the Rokinon 135 for astro. It is a great lens for the money. The 85mm version is great too. BTW - Rokinon, Samyang, and Bower are all the same company and the same lenses. For some reason, the Samyang versions of the lenses are slightly cheaper. Excellent channel Trevor - keep up the good work!
I completely agree with that focal length versatility and imaging capability. I have had great success using the Askar FMA135 lens. It is also a good product for this focal length, and probably a lot cheaper too. Of course it is not suitable for anything larger than a crop sensor camera. You can see several 135mm image examples on my UA-cam channel as well.
I hear good things about this lens. Both super sharp at f2 and not expensive.
Have you tried Meade ETX90 for astro? you can get them used for 100-200$, very potent lens/telescope. unbeatable for the money. blows away refractors costing 20x more. and it's quite compact.
Hat's off on your lens introduction and tutorial Trevor. You save us so much time and guess work. We will all excel together to explore our viable universe. Your shots are amazing !!
Rokinon is just a brand name (often used in USA). I can find the Samyang lenses as Samyang or Dörr (German photo accessory maker/seller). The lens is exactly the same.
Thank you so much for all your work. I just purchased the 135 after debating where to start and how much to invest, I am excited to start somewhere, get absolutely hooked, and spend lots more 😂
Samyang / Rokinon. Best bang for the buck lenses in most Astro applications.. Constantly use my 21mm F1.4. Lens with a Sony A7iii .. Outstanding results @ F2.2 Super sharp minimal distortion .. Relatively easy to focus.. Light weight.. Nice overview/ review... Subbed..
Looks like the perfect lens for capturing some of the larger nebula like The Veli Nebula.
Absolutely!
You know there is only one thing the matter with dogs, and I know you will agree is that these wonderful creatures don’t live long enough. Thanks for the Astro photography guidance.
I have used this lens with the SW Adventurer for a couple years. It is amazingly sharp, has a long focus adjustment (it must rotate 270 degrees!) that makes fine tuning easy. This is also a great portrait lens. I use f4 for and the sharpness is incredible. Samyang is a brand and the parent company. Rokinon, Bower, etc. are just brands. There are multiple versions if you are buying used. I believe they made one which was just about the same less the metering chip.
Thanks for sharing that Kevin - I think I'll stick with F/4 moving forward! Cheers
Great point on the lens hood for flat frames. That has been my experience as well! Nice work on the videos as always!
Thanks!
Thank you Trevor for the great review. I currently use an 85mm Canon lens but am thinking of updating to 135mm. I've heard great things about the Rokinon lenses for astrophotography. Also thank you for pointing out how Stellarium has built in frames so that you can plan your shots.
I had a great time with this lens in La Palma with a Canon 1000D Mod and the Ioptron Skytracker - 2m subs at ISO800 - F4. I do find F4 to F4.5 is best with this lens.
Oh.My.God..you posted this now! My 135mm is already about to arrive 🥰
I ordered a telescope bundle from high point. They seem to be in denial that a customer could possibly get upset when they order an IN STOCK bundle to find that the only item actually in stock is the telescope. I'm waiting on two items still. Meanwhile high point is emailing me going "how we doing?"
Rate our service and how about filling out a review? I uhhh ...
Perplexed. I hear about how great they are. I'm waiting...
omg i never knew that about stelarium. Always a pleasure watching your videos. Especially when I always learn something!
I definitely favor regular camera lenses, simply because their versatility. The Sigma 60-600 is the next on my list.
just finished building my own skytracker. Now its time to look for a lense, I'll definitely take this one in consideration!
Congrats! I wouldn't even know where to start. 135mm is a great balance between reach and "forgiveness" in tracking - I'd say a great fit!
AstroBackyard well I didn’t know neither 🤷🏻♂️ Just started and developed step by step. 😅
Yeah that’s true. For longer focal lengths that would be a perfect fit. Especially with that focal ratio.
Jakn What type of tracking mount did you build, a barn door? Mind sharing a picture & description? Thanks
Astrobackyard!!...You need to get with "Stellardrone" as soon as possible. His music with your captures will change lives. A marriage from the heavens, you will not be disappointed brother. Bless you.
Great review Trevor. This lens is coming to Tenerife with me for some dark skies at altitude in September - definitely earned its place in my kit bag
Amazon has it for $419 as of Dec 3, 2019. Mine is on the way!
I was considering purchasing this lens to match with a Sony A6300. Thanks to your review, I'm making the purchase!
Samyang is exactly the same as Rokinon.....just usually cheaper. I have the 12mm F2.0 and it's awesome. Thanks for the great video
I was just looking at the Rokinon 135mm. I need replace my Mitake 135mm f1.8 that has a ton of aberration. Great image btw you just sold me on this lens.😁
Thanks Matt! Clear skies man
@@AstroBackyard Back at ya Clear Sky's.
Hear me out, 85mm F1.4, for people who dont have a star tracker. With 85mm you can push the exposure time quite a bit longer than 135mm.
Very nice pics, Trevor. You explain your subject so well; keeps me coming back for more. I researched the Trifid and Lagoon nebulae and saw they are well over 4,0000 light years away. That just makes your pictures all the more impressive. Enjoy!
Just picked this up for $265 CAD. Stoked
I just ordered this lens and I am waiting breathlessly to give it a try!
I occasionally use a Samyang 85mm f1.4 ... really exceptional lens ... congratulations for the video
Thanks Claudio!
Ah man, it was on sale on amazon early last week and I hesitated and missed my chance, really wishing I got it now! Looks like a great addition
Mylo put it in your Amazon wish list and they will notify you when it goes on sale again. Another trick I read on the internet is to put something you want in your Cart but don’t buy it in 2 or more sellers at the same time. Like Amazon, B&H, Adriana, etc. then 1 or more seeing that will offer you a better price to entice you to buy. Worth a try if you’re serious about buying it.
The Rokinon Cinema Lenses seem to have MUCH better tolerances than the photo versions of the same lenses.
Nice lens I use that fornax mount it's superb even with a heavy lens I have the Canon 7dmk2 with a canon 300mm f2.8LIS and if I get my polar alignment right I'm good for 420mm f4 and it's tack sharp no trails. With a wimberly it's easier not a ball head. Not thought about the Rokinon 135mm got the 14mm F2.8 was thinking about the Canon 200mm f2.8 but don't want to spend too much on Canon as I'm going Sony A9/A7mk4 soon with the 200-600mm keep at it man love your videos.
The Fornax is a torque beast! I run a Bogen 3025 head on mine, which occasionally has the camera hanging several inches off to one side. Even with a heavy FD 200/2.8 and A7s, it drives the imbalanced load just fine.
Very interesting. I'm often shooting with a Canon 6d and a 200mm F4 and I like this wide field. I also use a samyang 14mm and a 24mm for milkyway and night time lapse with good results.
The 6D with a 200mm is nearly identical to this focal length with a crop sensor! My 60Da at 135 becomes 202mm 😊
Nice results! I looked at this lens as I already have the Samyang 12mm f2 & 8mm f2.8 for milky way shots, however the price put me off a little. I'm currently using a Zeiss Jena 135/3.5 Sonnar for that focal length with a focal reducer on Fuji, it's sharp and on a tracking mount the slower aperture doesn't matter too much.
Great video budy ..i have the 14 mmf2.8 and the 24mmf1.4 great lenses Rokinon
Would it be better to get the 135mm f2 or an Askar FMA 180mm APO Refractor?
get your self a partner the way trevor looks at his Samyang 135mm f/2 ED UMC Canon Lens
Gotta love Rokinon
Andromeda special...I want that lens so bad.
Anyone know if the Cine DS version is good as well? I found a great deal on it.
Same lense different housing and same/slightly better coating
Xgkkxgskgsgk Dzksgldgldlz so it’ll work fine for astrophotography?
Taking this lens on my a6600 and star Adventurer to a bortle 2 site tonight!!
135mm on the 60Da crop sensor camera body is effectively ~215mm focal length. Meanwhile it's still only 135mm on my full frame Canon 6D so I have to crop in much more in post to get the same result.
It doesn't work that way. Your arcresolution (which is directly tied to focal length) will not change, you will just lose more frame with a crop, that's all. The lens doesn't effectively become anything other than a 135, regardless of the sensor you put on the back of it.
@@MysticMungusSlungus Yes the framing with a 135mm on his 60Da is 1.6 times narrower than my framing on a 6D. Equivalent framing for my 6D would require ~215mm.
That doesn't mean anything in astrophotography though. Full frame sensors are different sizes as well, they're not all standard. Using "effective focal length" in astrophotography isn't a useful metric. The only thing that actually matters is your arcresolution, and the square degrees/min/sec at which the framing occurs.
@@MysticMungusSlungus Yes his framing and thus target selection on his 60Da will be different than what others on a full frame camera will see. His field of view is narrower than what mine would be.
This lens is definitely in my list to pick up. For three hundred dollhairs in the secondary market how can you not want this capability?
This is by far the best sound recording using a lapel mic. The other sounds so echoic indoor. I think you may consider using it more.
Learning a lot form your channel so keep putting out great work. If you were starting out with a Sony APS-C camera would you recommend the Rokinon 135 or the Redcat 51 apo 250mm f/4.9? Just looking for a recommendation to make this choice easier. Thanks again.
Hi! Long time watcher and now trying to get into DSO using a camera and lens. Have you tried out the Sigma 135 1.8 Art series lens? I know it costs much more but was wondering if the quality of the Sigma Art 135 1.8 would be worth the extra money. Less CA? BTW, I have the Rokinon 12m 2.0 for wide Milky Way shots and love the lens.
Holy shit, it indeed is a cheap lens!
Damn, the quality of the image you can get with it is really great.
This lens is on bar in picture quality with the 1500$ and more 135mm lenses, but is cheaper due to samyang/rokinon and being manual
Ha! My Pentax K-3 may not be able to interface with all the software that Canons can, but I finally found a bragging point - it will control the aperture (F-stop) my Rokinon 135, LOL. The Astrotracer is nice, too, as can get up to 30 second exposures with the 135, where otherwise would only be few seconds.
More to the point, I did not think I would be able to get DSO's with this lens though, until this video. Thanks for the inspiration, can't wait to have a clear night off to try myself!
From what I understand, Samyang and Rokinon are just different names for the same company. They're branded differently in different international market.
Great video and great results! Which light pollution filter were you using here and where are you at on the bortle scale?
It's the Optolong L-Pro clip-in for Canon APS-C, and I think he's said on other videos he's around Bortle 6-7
I have a number of 135 lenses a Chinar 135 2.8 Pentax 135 3.5 M lens and the Takumar 135 3.5 m42 screw mount. I should try the Chinar lens for astrophotography
This is a general question? I took 190 30 second exposures of the region around Antares. I was surprised to how little nebula detail their was using Deep Sky Stacker. Did I do something wrong or do I need to expose for one to two minutes? The camera I used was the Sony a1 with 70-200mm GM at F4 and at 200mm. Thank you.
Yeah, sure Trevor, blame it on the garage. (sarc) Great work, both videography and astro.
The 'ol blame it on the garage routine. lol
Great review thanks for your work it inspires the rest of us. I notice you use the Fornax mount, how do you like it and what would you say are its pros and cons compared to other similarly sized/powered mounts such as the astrotrac, skywatcher Star adventurer, vixen Polarie ..etc? I’d really like to get into Astro but the only clear skies I get are when I travel, so I need a portable kit and I’m sure many are in the same boat. Thanks again for your work.
As a suggestion for a longer format video it would be nice if you opened up with a few sample intro shots of what the results are before going into the details or alternate between tech and picts. Also zooming in on those nebulas in Photoshop a little closer would be nice-not all the time are we on larger monitors. I was using an iPad and wish those details were bigger.
Great content and thanks!
Have you ever explored the Laowa 100mm 2.8 lens? It is primarily a macro 2x magnification lens, but it focuses to infinity as well. For photographers like me who have a wide range a photography interests, we could use the same lens for macro photography and astrophotography if the images are well beyond acceptable level for shooting the stars.
Do you have any videos about what one could shoot with a DSLR without any kind of tracking?
Hi i have a Canon eos rebel sl3 and i wanted to Buy a rokinon 14mm lens for astrophotografy i'm just worried that if i Buy it it could damage My camera or You think it wouldnt? The rokinon lens is ef mount so i think it is compatible. But i was reading that sometimes give error on the camera and it worries me. Thank You.
When you get the chance, you need to attempt some mosaic work! 135mm is a beautiful focal length for wide field composites. Gorgeous shots Trevor!
if you stop to f4 why can't you just use any 70-200 2.8?
You could but the optics are different. A prime lens has most of the time better image quality than a zoom. Especially when its optimized for astrophotography
I got these lens for 260$ on Ebay and i love the quality so far but i can't use live view to properly check the focus
I'm a newbie i might be doing something wrong,also it says no len detected Model-Canon Rebel T7i
14:16 Best Part
Someone stayed until the end! Haha. My wife didn't notice the branches were gone until she watched the video. She said 'Now the tree is unbalanced" 😂 Oops!
@@AstroBackyard Yup. Hahah i always watch your videos fully, i really like your content i will buy my first DSLR soon.
👍👍Thanks Trevor for yet another video full of valuable informations!
I guess this camera's sensor is astro mod? Would a "regular" sensor yield similar results? Which tracking mount did you use?
Also, since full frame sensors are better at gathering light, wouldn't there be a benefit using a full frame camera for astrophotography ? Is there any equivalent filters for full frame camera? (If so, could your share description or link on these filters?)🦉📷🔭⭐☄
I am ordering one today. Hope I get a good copy!
Does the lens require some field flattener? How’s vignetting? The appeal of RedCat 51 is that Petzval design and flat images. I’ve used 50mm prime, 85 mm prime (Nikon) and 200-500 mm telephoto. Those prime lenses have about 40% of useful flat image with round stars...
It dependso n the camera, but with full frame/aps-c, it does vignette wide open. You can easily correct this in post processing, using flat frames. As for distortions, they're very well controlled! The only thing that will flatten, is your wallet :) But it's worth every penny!
Pierre Thanks! I may consider this lens then. It’s not that much cheaper than the RedCat 51 though. Apropos wallet - hah 😄 I’m in the wrong hobby to worry about it... it gets attacked regularly 😄
I bought it today, I can't wait!
one year later, I had to fix the aperture ring but it was a good buy
Wow man, GREAT CHANNEL! I will be filming this kind of stuff for a music video. Would love to get my hands on that lens haha. A friend from Austria will also bring his equipment for the shoot so maybe he can get one in the meantime. A big stargazing scene in Switzerland in September and some in Northern Canada throughout winter when it's dark again.
Trevor, I know you said you're in Canada in a place where there is light pollution, but have you ever mentioned what Bortle class your area is?
Never mind ... I found out from one of your other videos.
Can't decide, this or the Redcat 51?
Since this is a full frame lens on my Canon 80D it would be 216mm correct?
Well, its still a 135mm lens, but it will act as 216mm on your crop Canon
Good vid Trevor... what kind of tracker works best for someone just entering the astrophotography field?
What's the difference between this and the 135mm f2.2 version?
Is the Astrophotography performance similar?
Never heard of stretching a tee shirt over the lens before. May be a vid on this?
I have a video about taking "flat frames for astrophotography" and should help!
They say the focal length equivalent is 202 mm when shooting on micro four thirds..what does that mean?
I would say it's actually closer to 270mm, as Micro 4/3rds has a "crop factor" of 2 (135 x 2 = 270).
You may be thinking of a Nikon/Sony APS-C sensor, where you will get ~202mm as the crop factor is 1.5 (135 x 2 = 202.5).
The crop factor roughly correlates with the diagonal measurement across the sensor. For a full frame sensor it measures about ~43.2mm from one corner to the other, and a micro 4/3rds sensor is 21.6mm, which makes your image appear more zoomed in (43.2 / 21.6 = 2), in reality it's only capturing the middle portion of the image that is projected by the lens.
In other words, an image from a 135mm lens on a Micro 4/3rds body will have the same appearance as one from a 270mm lens on a full frame camera (although full frame sensors have other benefits).
The correct term is 'field of view' fov, in degrees. This lens has a diagonal fov corner to corner of 18.8° on a full frame sensor.
On a m43 sensor, the fov will be half, = a diagonal fov of 9.4°
Hi Trevor! How do you point to the correct region of the sky having a long lens like this? I'm currently getting my feet wet with a 18-200 zoom lens and take advantage of the wide end of the zoom to do a rough composition before zooming in. The issue is that is f/5.3 at the 200mm end so I was wondering how to manage this with a prime long lens.
It can be tough in regions with no bright stars. It may take some trial and error - I use the Stellarium mobile app for a rough idea - and then take 10-second test images to frame things up. Targets like the Sadr region in Cygnus are dead simple because the Sadr star will show up in your live view display. You can frame it up in real time :)
Hi. Could you change the 'line colour' in Stallarium so it is easier to see the frames. :)
I know this is not what your channel is about, but you did make mention on what I'm interested in. I'm looking at filming owls (PS I follow your other channel) and other things at dusk, do you find the video quality good? I shoot with a M43 Panasonic G9 and think this may be a cheaper option then the 1st party prime lens.
Now all I need is a tracking mount =)
Your videos are fantastic love watching them what sort of lenses would u suggest for galaxies
i was checking our your example images and was wondering how you were able to get such zoomed pictures of like andromeda for example? i took some but i couldnt get any zoomed pictures like that
Another great video. Love the images you captured. I’m a Nikon shooter. Are drop in filters made for Nikon or do I need to pick up a Canon body? Love the tree trimming at the end. It’s little things like that, that makes you and your approach to Astrophotography so relatable.
Question: Have you ever told us the configuration of your laptop & imaging computers? Wondering how much processing power & ram we need. Both my laptop & imaging PC’s are old but running Win 10 Pro 64. Thanks - Dave
Awesome lens. May have too look into it
I am currently shooting Olympus (MFT) but am looking to upgrade to either the A7iii or Fuji X-T3. I am so torn, but at least I know what one of my first lenses will be 😂
Any advice or suggestions one way or the other would be greatly appreciated.
Ben Mercier if you’re mostly into photography, i would highly recommend the a7iii over the xt3. While the xt3 is a fantastic camera with very healthy features, especially for video, the larger full frame sensor of the a7iii will give you a couple more stops of dynamic range and less noise.
Rokinon (in the USA)
Samyang (in Korea)
it's same lens....made in Korea.... Not North !!!
good quality and low price.
Great video and review ( and Greetings from the U.K) Looks a great lens... I have a Canon 80D (crop sensor) and as you said in your video, it’s not really an ideal lens for singular DSO’s such as galaxies and such, but could you recommend a lens for the 80D that I could shoot those with , especially Andromeda?
Are these examples in the video from a crop sensor? It seems like crop sensors are actually more useful for a lot of astro targets. I have been thrilled with the Milky Way shots I have captured so far using the Rokinon 14mm f/2.8 on my Canon 6D and now I am looking for a good lens that will take me to the next step in this hobby. I was thinking that 400mm might be a sweet spot? I guess it depends on the targets, which I am not all that familiar with yet. Anyone have any thoughts about taking the next step from wide angle nightscape astro shots to something more targeted? I have the Star Adventurer star tracker which seems capable of handling 300-400mm or more.
Absolutely stunning! As you said, the DSOs look awesome at 135mm (seems like some sort of a Goldilocks' zone for Astrophotography :P) Quick question : What software do you use to identify and label the DSOs at 13:32 ?
@kunalkulkarni4825 I use Siril 1.2 , it has aan object annotation feature.
Great video. Did you use a bahtinov mask for focusing?
Just watched someone using Jupiter to focus, said when the moons come into the screen you're in pretty good focus with camera lens
which settings can bring me amazing results using this lens ? Aperture, exposure time using tracker and also iso please? i'm using a sony a7iii with samyang 135 f2.0
Hello i have old lens from damaged LCD projector... the lens 113mm f2.5 made in japan...
