I recently purchased a budget prime lens Yongnuo 25mm F1.7 for a friend, so I thought I could do a quick review since I was genuinely curious about how this lens performs, selling for about USD100 only. While there are many other 25mm budget prime lens options out there, they were all manual focus lenses and Yongnuo was the first to release a 25mm prime for Micro Four Thirds mount with full AF capability. I also have written a blog review for this lens here: robinwong.blogspot.com/2021/0...

I am not sure what happened to the pricing at some parts of the world. but here in Malaysia, Panasonic 25mm F1.7 is about RM1000/USD250, you can get about RM750/USD190 at bargain. The Yongnuo 25mm F1.7 I purchased at RM385/USD90. It is practically HALF the asking price of Panasonic 25mm F1.7.
The only reason the Panasonic lens is selling so low in some parts of the world is due to poor sales strategy and promotion control implementation over the years that eroded the value of the lens in the market. While this is good for customers for spending less, it is hurting the manufacturer for earning less.
At least Panasonic maintains their pricing reasonably well here in Malaysia. RM750/USD190 for 25mm F1.7 is still a fantastic price.
The Lumix 25mm f/1.7 is currently on sale in the UK for around GBP150, equivalent to around USD200, but this is an increase from recent years. I bought one for around GBP120 (USD150) about 3 years ago although I've hardly used it
I haven't seen the price of the Panasonic 25mm f1.7 erode over time, ever since it was launched the price has been consistently low. It is always cheaper than its rival, the Oly 25mm f1.8. Regional price variations happen for all kinds of reasons, if the Yongnuo is a bargain in Malaysia, then perhaps it has a chance. In any case it is great to see a third company make an AF lens.
Thanks for your help. Unsubscribed
Question so iam looking for a good lens that has auto full focus and manual for my Panasonic G7 Lumix I know the YONGNUO 25MM F1.7 IS GOOD not so bad I watch your video..but has little quality flaws ..so is their a lens around the prise range as this one that you cud use to vlog as arm length and thats good for landscape filming and photos? Hope to hear from you soon.
Great to see some budget lenses get a fair review. It may not be for everyone but it's going to be great for some. Keep up the great work. Thank you!
Your images pleased me, Robin. Thank you.
Thanks Robin, and may I say, you are looking very fit and well. Always a joy to see your smiling face. The lens looks great. I have an Olympus 17mm, that I love, but seeing your marvellous street shots, I'm very tempted to get a little closer. Take care.
Decently priced and promising offering for MFT shooters on a budget - thanks for the review Robin
Me too!
Thanks Carmen, more similar videos coming soon
@@robinwong
Robin , I will be looking forward to seeing more like this .
Great review, thank you Robin.
Nice lens! Thanks so much Robin!
Thank you very much Robin, excellent review.
Thanks, glad you liked the review
Thank you very much, Robin... 👌👍👍🙏
No worries
Thanks for the review. Looks like a nifty little lens for the price. Next time I have some extra money, I might pick one up. I have three lenses for my Olympus OM-D, they're all Olympus zooms, a 14-42mm, a 40-150mm and a 70-300mm. Don't currently have a prime 25mm. Since I've been pretty low on capital lately, this might be a suitable option.
Great Information Robin! Thank You!
Thanks Doug, glad I can share
Wow, that is a well performing lens with few easily corrected flaws. Now surely is a great time to start out as a photographer on a budget. I wish shooting with fast primes was that affordable when I started out :)
Also: any plans for "Let's do this!" merch?
Great honest review. I picked up the Yongnuo 42.5 f.7 (2nd edition - Rob Trek hated the first edition!) and was pretty happy with it. I was thinking about the 25mm and you have talked me into it! Not stellar, buy good enough for holidays, where I don't want to risk the more expensive kit, I have. Thanks for the honest and thorough review.
That was a great video from Rob. I would think that the optical performance, build quality and AF would be very similar between the two lenses.
Great in-depth review!
Thanks Jeremie.
@7:30 Hey Robin, nice Robin! 😂 Great vid! Good bargain lens, it sounds like! Would love to learn more about lesser known brands of lenses like this for the MFT format.
Thanks Packie, more similar content coming for sure.
Yongnuo 25mm F1.7eith focal length with a bright f/1.7 maximum aperture to suit working in a variety of situations. cool i want that lens
Skinny Latte on way - respect from UK.
Thanks for sharing, bro. Looks like an awesome lens for a little money.
If budget is a big concern, yes, great lens it is! I'd still go for Panasonic or Olympus though.
I have a an DJI Inspire 2 with the Zenmuse X5S which is a M43 camera. The lens is a F1.7/15 and it works great on my M1X.
Love the black birds photo @ 4min 13 sec !
Thanks, that's my favourite too
Terimakasih pak Robin
Thanks Robin, great review we can’t all afford Pro lenses
Looking at a reputable store, in Canada the Yongnuo can be found for around $145CAD (1:0.77 USD) and the Panasonic around $200CAD as of writing. I think the $55 difference for a new M4/3 user could be justified here. Get a step up ring to say 67mm, get a nice polarizer, ND filter, simple lens hood, and you're set to shoot a lot of interesting subjects and compositions than just a lens alone.
Not to discount the Panasonic, I own one and I love it dearly when I get a chance to use it. A very nice lens on the budget side of things. I am personally surprised how well the flare was controlled on the Yongnuo lens!
Great review, Robin. Nice to see you out and about! Hope they produce a few wide- angle lenses. Cheers, Dave from Scotland.
They do have a 14mm f2.8 for canon I believe. Fingers crossed for MFT wides...
Thanks. Let's hope they make more lenses too.
@@AbbasBinYounas Thanks for that - lets hope so.
Thanks Robin you sold this one im on a tight budget so I must have it ill have to get you a coffee 😅
Hi Robin, thanks for reviewing the Yongnuo prime lens 25 mm f1.7. It would have been helpful to compare the lens with established lenses from both Olympus and Panasonic. Not only the price, but also dimensions and weight would have been interesting. The Yongnuo lens presented seems to be a monster in terms of size - compared to the M. Zuiko 17 mm f1.8 or the Lumix 25 mm f1.7. The price in Amazon Gemany is 125 € (March 7th, 2023).
Crazy how affordable these third party AF lenses are becoming!!
Nice review, Robin. Keep safe!
Thanks!
Nice review.For imaging quality, how it compares TTArtian 35mm f1.4? I hoped for this comparison
Thanks a Lot for the review dear Robin! And allow me suggest the Sigma 56mm F1,4 for another video, i have heard many good things about this lens, but i would very appreciate to hear your thoughts about this Lens. Se you!
Thank you so much Robin! I love your every videos. They are educational and down to earth, unlike those pro "reviewers". And I'm wondering if you tried 20mm 1.7 lens and maybe will you do review of this lens someday? It's right in between 35mm and 50mm focal length so for me it's very versatile and not to mention pancake size and 1.7 aperture. Thank you sir and I wish you the best Robin!
Regards Ari
Thanks for the kind words, I appreciate them. The Panasonic 20mm f1.7 is a good lens, but I won't recommend it for a few reasons - the AF is one of the slowest for Micro Four Thirds, and that's fine because the lens is rather old. AF was not that great back then. The lens is sharp, but the bokeh is harsh, and the lens has some CA issues.
@@robinwong I agree. I sold my 20mm f/1.7 (original model). The AF was slow and didn't inspire confidence, and it was really noisy, making it unsuitable for video. I think the Mk II version of that lens is improved.
Good review; I might consider it if I'm looking for a 25mm.
Thanks, I do what I can!
That must be the lens you used in the low light video which I asked about. I really like the look of that at the start of your video. The bokeh in the background was special enough I asked which lens you were using. I was impressed enough to watch that opening a few times trying to figure out where that look came from. Definitely a nicer and cleaner oof rendering than the Pany 25/1.7 I got as a light weight inexpensive throw in pocket and have with me lens.
Nope. That was not the lens. If it was, you will probably be able to see my forehead and half my face. 25mm is too narrow.
@@robinwong Now I still wonder what that lens was. :)
Good day sir! I've been a fan of your work :D I'd like to ask if this lens works well with the first EM5 as well? Their website says that this is only compatible to the em5 mark 2 up. Thanks!
Thank you for the review. I don't think it is the first budget lens; I bought the Panasonic 25mm f/1.7 when it came out for $99. Also, I just can't imagine why anyone would prefer this lens over the Panasonic. It will not have as a good a resale value. Also, what about in camera software corrections that communicate with the lens? I would have appreciated side by side shots under the same conditions. Tx.
Great review! Thank you! Glad that you could go out to shoot :)
Thanks, I feel the same way too!
Great outdoor video
waiting your next review 8-25mm 😅
Thanks. The 8-25mm will take a lot more effort to make.
Speaking of remarkable value, I recently picked up a Samyang 35mm F2.8 FE pancake lens for $150 for my Sony. Fantastic little lens for street shooting, sharp even wide open (unusual for cheap lenses), and has minimal distortion. Coupled to the A7C, the overall form factor is downright diminutive, and much like the older style Rangefinder cameras.
Samyang is pretty hit and miss on lens quality, as they have some really excellent value lenses, but also some not-so-great lenses.
For well-established mounts, there’s generally some really nice value lenses to be had if you’re willing to do your homework. 😉
Unfortunately they don't make AF lenses for Micro Four Thirds!
@@robinwong Another random thought that videographers often like to do, particularly those shooting Micro Four Thirds and APS-C/Super 35. Have you tried a Metabones Speedbooster adapter? They allow the use of Full Frame lenses on smaller sensors, not just a cropped portion of it, but the entire image circle projected. This is because the adapter is also a focal reducer. Exposure-wise, you can also expect much brighter aperture settings, as the light is focused onto the smaller area.
It would make for a pretty cool video. Though to be fair, they’re expensive, and probably only really useful to videographers that use multiple different systems. 😉
I was one of the people who requested this so thank you Robin. I have the Olympus 25mm f1.8 so I don't need this lens, but I am always curious to know how good or how bad very cheap lenses are. I was impressed that it has a metal mount which is surprising for the price.
I think for a lens that you will use a lot it's worth spending more for a better lens if you can afford it, but budget lenses are good for occasional use or trying something new. For example I would like to try out a fisheye but wouldn't want to buy a very expensive Olympus, so am looking at the 7artisans and TTartisans lenses.
I agree with you, not everyone will have a need for 25mm prime, but the price is so low, you can own one without putting much dent into the bank account.
I have collected three fisheyes for my Olympus: Rokinon 8mm, Laowa 4mm circular, and the Olympus "body cap" fisheye. All three are inexpensive and surprisingly good quality. The Rokinon and Lawoa have metal construction. The cheapie body cap fisheye is a blast when you just want to walk around doing "shutter therapy". 😁
@@Centauri27 Thanks Carl. I was considering the body cap lens but was put off by the fixed f8 aperture. Rokinon are sold under the Samyang name in the UK and get excellent reviews so I'll probably get one.
@@caw25sha Don't be too put off by the fixed f/8 aperture of the body cap lens. I've taken excellent indoor photos in shopping malls, office buildings, domed conservatories, etc. with this lens! Don't forget that with the super wide fisheye, you can drop the shutter speeds really low, meaning even indoor shots don't need to go above ISO 640 or so. (But note that the body cap fisheye isn't 180 degrees like most; it's only about 140 or so I think.) The Lawoa 4mm is wild--it gives a 210 degree view! If you'd like to see samples of some of my body cap fisheye shots, I'll be glad to send them to you.
@@Centauri27 I've used the Samsung (aka Rokinn) 7.5mm MFT lens and it was very good and if I did pro fisheye work I'd buy it. But I use the lens cap lens and it goes everywhere, it has got me out of tight spots(literally!) many times. In fact, when my camera bag got stolen it was the first lens I replaced - a no brainer, just so tiny and useful (and cheap!). And it de-fishes very well in post so you can use it as a 9-10mm ultrawide at a pinch. I love that lens!
Hello. Thanks for the video. Have you heard about the problem with stabilization of this lens with some Olympus models? One person wrote that the matrix stabilizer with the Yongnuo 25mm F1.7 does not work on the Olympus PEN E-PL9 camera. There are no problems with other lenses. Does the stabilizer work on your Olympus? Have you checked?
Hi Robin thanks as always for the video. Any chance I can ask you a question off topic? Could do with a voice of experience with Olympus.
This lens looks great value for money. Since I have a Panasonic/Lumix Noctricron 42.5mm with f1.2 I do not need to purchase. If anyone wishes to take photos in low light then this lens is fine. Super for indoor without a flash or in caves etc.
I'm no pro photographer but I really like the image quality from this Yonguo lens - at f4 and 5.6 the quality is excellent - and for the price (I paid £98 from Amazon UK) it is an absolute bargain.
Just wondering, is this lens compatible with Olympus EP3?
Ok so what micro 4/3lens you recommend at this prise point that has automatic focus and manual with better quality image specially for video filming like UA-cam .hope to hear from you soon.
Olá, ela funciona na primeira versão da olympus em5?
how good is the lumix 20mm f1.7 sir robin
How does it compare to the Lumix 25mm f1.7
Auto focus?! My motherland rocks!!!!!!!!!!!!!!!!!
What about tracking, is it good?
Hi boss ini lens boleh tak guna kat Olympus pen epl2
Nice review. I will get 1.
Has anyone used this lense on the EM10 mark II? Amazon says it’s not compatible (it is but starting on the Mark III)
Looks similar with the panasonic 25mm f1.7, except the less intense chromatic abberation on the panasonic. In my country panasonic is on sale for about 150 USD
The Panasonic lens is smaller in build. I can't comment on optical quality since I never used the Panasonic before. Here in Malaysia the Panasonic is USD250 on normal price.
@@robinwong lumix 25mm f1.7 is one of the best budget lens. I've used it since 2018 and got great results from it. But similarly, the bokeh isn't perfectly round like yongnuo, the sharpness and the vignette is quite similar, however i never notice any distortion from the lumix. Overall the yongnuo is a great value if you have a really tight budget. But if you have a bit more, i'd suggest buy the lumix instead.
To me the best value lens is the Yi 42.5 f1.8 you reviewed earlier. Thanks to you i own one right now
hola buena noche queria saber si ese lente es copatible con una canon 5d mark iv muchas gracias
Good review, the lens has quite a few problems that can be corrected in post. No thanks, better to save up for a better lens.
Abang robin ... Ni bole masok dekat gf9 kn.. 25mm 35mm 42mm 50mm mana lg elok bang
I have to spend my money on other things - both my EM-1 and EM10 Mark III have broken in the last 24 hours. Do I invest in another EM camera having already lost hundreds of ££££ or take the opportunity to move to full frame?
can i have the link you used to get your lens please ?
Can use on Canon 600D?
good review I bought the 30mm Samsung for a prime. It still saved a bundle over the 25mm 1.2 This would have been ok.
I never realized Samsung makes Micro Four Thirds lenses. I must be in my cave for too long.
@@robinwong I suspect autocorrect error for Samyang?
Sorry I was thinking Sigma and somehow typed Samsung.
@@cmartin_ok It may have been auto correct it has caught me many times
What do you say about AF in video?
Works on lumix g7?
Can anyone confirm if this lens works on an Olympus EPL-1 ? I read somewhere that the camera won't talk to the lens....looking to verify that.
hi anyone planning to buy this lens is this compatible with em10 mark 1?
Hi Robin do you know if they will have a 7mm or 10mm
I don't think Yongnuo will be investing heavily on lenses. They make other accessories as their main focus.
Got rid of my Lumix 25mm because of "focus breathing" - the focus changes with the f-stops. Hope this is better.
Eh? That can't be! Focus changes with focal length on zoom lenses, that's focus breathing. But for a prime, the aperture alteration (by opening or closing the diaphragm) has zero effect on focus ... unless your lens had some weird mechanical fault where the aperture mechanism was interfering with the focus mechanism - these 2 should be completely separate
I think you mean focus shift (where the focus that is acquired while the lens is wide open "shifts" when the lens is stopped down to actually take the shot).
In the Panasonic 25mm f/1.7 this das visible at apertures between f/2 and f/5.6. At smaller apertures, the greater depth of field was enough to mask the issue.
I did not encounter any issues with focus breathing on the Yongnuo. I have never tested the Panasonic 25mm F1.7, so I can't comment on that either.
@@AndrewSowerby Yes, that's a better term.
I would pick the Panasonic 25mm f1.7 or the Oly f1.8. Resale price of a yongnuo is 0 while the other two keep their value intact. Looks cheap but it isn’t IMHO.
Agree.
Is it obvious how to fix the distortions you talk about with this lense in post-processing. Can it be done in Olympus workspace? I have never done post processing in any serious way.
All modern post-processing software can fix distortions, and yes you can do that with Olympus Workspace. Make sure you shoot RAW for more control.
@@robinwong thanks for that ...
Plenty of photographers prefer to just shoot JPGs and skip all the post processing. And I suspect most "beginners" do. Yeah, you can get the best photos by editing them on a computer with good software, but not everyone likes the process.
Why would I go for this over a used Olympus or Panasonic for the same price?
This lens does not work on my blackmagic 4K camera
👍
Cheers
I ordered one for my old E-P1 and it turned out they don´t work together, no matter what I try! The display turns black when I mount the lens and the camera becomes unresponsive. The lens works just fine on a Panasonic GH2 and the E-P1 works with any other lens I put on it, so it must be a compatibility issue. In other words, I just wasted 100 bucks.
Well, I have Panasonic 25mm F1,7. Is ” Your ” lens bettet?
Since i see no one talking about it, wich lense u think is better this or the panasonic 1.7
Lumix at $147.99 seems like a better deal. In the past, Lumix was under $100, but perhaps never again, who knows. Really, $115 for a brand X compared to buying a Panasonic for just a few bucks more makes a whole lot more sense to me.
To some people, 50 dollars is a lot of money, and can survive for weeks on food. If that difference is not a problem, and budget is not an issue for you, of course like I said, there are better options. It all comes down to how much you can, or are willing to spend.
What's this ??You are ..gasp..OUTSIDE!!
In case you missed the last 2 videos, I was already outside for 2 weeks.
This is really a comment in response to the poor C-AF performance you saw using this lens to make your latest video [ ua-cam.com/video/eB-C1Mh8v4g/v-deo.html ] , but I thought it made more sense to add it here (hope that's OK).
So, regarding the Yongnuo's autofocus issues in video on your E-M1 MkII:
I was looking at the product compatibility matrix for this lens on Yongnuo's site to see if my little old E-M10 MkII was listed, and it isn't, only the Mk III and IV are. However, amazingly, NONE of the E-M1 marks are listed at all, so that might possibly explain why you're seeing it lose you sometimes in C-AF.
In fact, Yongnuo only list the following cameras in a compatibility matrix on their website:
Olympus: E-M5 MkII, E-M5 MkIII, E-M10 MkIII, E-M10 MkIV, PEN-F, E-PL9, E-PL10 (7 models in total)
Panasonic: G100, GH5, G9, G95, G85, GX9, GX85, GF-10, GF-9 (9 models in total)
I was surprised to see such a short list.
By "compatible", I assume they mean "full" compatibility (you would at least expect acceptably good C-AF, even with tracking), but I guess that single AF works fine on many more bodies than they list on their site. It's probably also more of a budget issue: Yongnuo can't test their lens on every single MFT body out there, especially considering the huge array of advanced features (in-camera focus stacking, Starry AF, etc, etc). However, that means we are doing the product compatibility testing for them, and I don't particularly like the idea of that, despite the low, low price. Of course, as you have noted yourself before, just because there's a common MFT mount, that doesn't mean that you will get the best performance from a Panasonic lens on your Olympus body or vice-versa, so I suppose that with a third-party lens, some issues can be expected. As long as they are fairly minor, they may not be a deal-breaker.
by compatibility it means they have physically tested on the camera bodies mentioned
To me, the build quality seem not cheaper than the 25mm F1.7 from Panasonic.
Probably this one is built better than Panasonic one
The Panasonic lens is about $33 more expensive ($147.99 vs $115.00) on amazon.
@@johnsmith-gs4qf Seems like the days of $99.99 sales might be gone, but really the Panny is a much better deal at $150. And the Lumix build is fine. I never use a lens for a hammer anyway. ;)
I have not used the Panasonic 25mm F1.7 before. Is it really that bad in build quality? I'd think it is close to Olympus 25mm F1.8, which is an excellent lens.
@@robinwong For me, the lens feel solid but still plastic. Don't get me wrong, I have this lens and I love it. It's a lightweight and really sharp lens.
surprised a 25mm has THAT strong barrel distortion?
Not much of a difference here in the UK in price between this lens and the Panasonic 25mm f/1.7. The cheapest, I can find the Yongnuo without importing it myself (and paying duty) is £128. The Panasonic will cost you £148 and you will get it from a shop with guarantee etc.
The Panasonic 25mm f/1.7 is available for €140 in like new condition on mpb, but the reputation that lens has got for focus shift between f/2 and f/5.6 is a bit of a deal breaker for me.
I think a standard 50mm (equivalent) lens shouldn't have such a flaw - it's the easiest focal length to do really well.
I hope that the Yongnuo YN25 doesn't suffer from this issue too - nobody seems to have reported that it does.
I’ve got the Panasonic but if this had been available at the time I might have saved a bit of money and gone for this instead!
I honestly don't think these lenses are a great value when you consider that in the used market the first party equivalents go for similar prices to these new and are smaller, lighter, and have more features.
I don't want OM Digital Solutions to come up with same focal length overlaps when it comes to lenses. We need diversity.
@@robinwong I guess if I am going for a third party lens I'd like to see more interesting feature sets than the first party. IE really close focusing. Or a weird focal length. Or a smidge faster. Or something ergonomic like a physical/by-wire aperture ring. Not just "cheaper."
They're practically first party now but when I was first getting into photography 10+ years ago one of my favorite lenses (on crop and especially on full frame) was my 24mm f/1.8 Sigma EX DG "Macro" (in quotes as its not a true macro by definition) Fast 24mm for a low price, and can focus to ~7 inches. Really fantastic lense to get creative with and can get crazy shallower than you'd expect with that 24mm FOV because of how close you can get to a subject.
The AF isn’t very good on this lens.
