If you’re using an 18mm lens on a full-frame (35mm) sensor at f/5.6 and focusing at infinity, here’s how to calculate where the sharpness starts: The hyperfocal distance formula is: Hyperfocal Distance = (f²) / (N × c) + f Where: • f = focal length (18mm) • N = aperture (5.6) • c = circle of confusion (0.03mm for full-frame) 1. Calculate the hyperfocal distance: Hyperfocal Distance = (18²) / (5.6 × 0.03) + 18 = 324 / 0.168 + 18 ≈ 1946.57mm (~1.95m) 2. When focused at infinity, the sharpness starts at half the hyperfocal distance: Sharpness starts at = Hyperfocal Distance / 2 = 1946.57 / 2 ≈ 973mm (~97cm) Answer: With an 18mm lens at f/5.6 focused at infinity on a full-frame camera, the sharpness starts at about 97cm (3.2 feet) and extends to infinity.
I figured it was for landscape photogs who want a small lens. That’s why I bought one. Similar appeal to the Laowa 15mm or Sigma 17mm pancakes, but even simpler and cheaper
Thank you for the review! I bought this lens for my leica T. One of the first reason was the build quality and the small, compact size, yet not a plastic lenscap lens. The 18mm becomes ~28mm, because the leica T's apsc sensor, which is the second reason. It seems to be my walk around wide focal length besides the more "normal" 50mm ff equivalent. The f5.6 like you mentioned is the set it and forget it style, which is perfect for travel and street photography. I had a few days with it, and like it, but I need some practice with the focusing. This is my "weekend" setup, so I prefer the lenses which need some time to handle, it slows me down, and clears my head after a busy week..
Try to read about hyperfocal distance If you point to a person at 2 meters with an 18mm Ff lens @5,6 you get hyperfocal and everything between 1.3m and infinity should be in focus, you just have to know where it is in the focus ring and mark it.
That was my expectation going into using this lens as I've used that theory with rangefinder film cameras but it was hard to peg down. I think I may calculate it and engrave that distance onto the lens to mitigate further annoyances. Thanks for the comment and input.
@aaronsambeyfilm I'm looking for a wide angle lens for traveling, usually in my case 35mm do 90% of the job, I was looking for something small for those moments to pair with my new Lumix s9, I won't do astro, and I prefer to spend my money in other gear so I thought this lens could be that lens... Can't wait to see the second video, thanks for the review
@@aaronsambeyfilm hey, I've been studying where could be the 2m spot and looking all the other FF 18mm MF lenses it should be towards the end, if infinity is 100% of the lever, 2 m should be about 75/80%, give it a try, for those street shots including people and buildings i guess you could stop over there to get a point and shoot
It seems basically to have been made for the S9. Panasonic released that with a ridiculous 26mm that is entirely useless except as camera body cap. But this 18mm does several things better: 1. The focus throw is reasonable 2. f5.6 is better than f8 3. 18mm covers a focal length not covered by normal lenses 4. It's a reasonable price (if the 26mm didn't come with the camera, it's got a stupid RRP for what it is) I'm going to get this and use the 26mm as a body cap for cameras not in use. (No one will buy it.)
I bought the 26mm with my own hard earned, and love it. Fabulous little lens. Tiny, sharp, nice colour and contrast, really fun to use. You just need a little bit of imagination, and a little bit of skill to use and enjoy it. It's a little bit out of the ordinary, which I see as a good thing. Personally, I'd rather this 18mm was f8 rather than 5.6 myself, but that's just me
I have this on order for the exact reason you mention in your description: try wide photography before committing to a 16-28/16-35 from a big name. I think that a lack of variable aperture and markers is a huge miss too though. I have the 25mm f2, with the clicked aperture ring on the lens tip, and having that system on this lens to stop down would be great for landscape shots. Might just have to find a few useful ranges and scribe them in for the other issue.
Thanks for the review. I liked this lens and the picture from it right away. I like the wide angle. I liked your sample photos too. I will definitely order this lens for myself.
@@lukaszklopotek It very much has focus peaking. The issue isn't focus peaking. It's that most things appear in focus at 5.6 on a wide angle lens so critical focus with focus peaking becomes more difficult as everything ends up having peaking lines on it.
I use the Lumix 26mm f8 on my S5, and manually focusing it is absolute childs play. I have a magnified picture in picture focus box set up so it activates when I move the joystick, with focus peaking it's so simple to get your focus in exactly the right plane in the magnified view whilst still being able to frame your shot. It's an absolute pleasure to use
If you’re using an 18mm lens on a full-frame (35mm) sensor at f/5.6 and focusing at infinity, here’s how to calculate where the sharpness starts:
The hyperfocal distance formula is:
Hyperfocal Distance = (f²) / (N × c) + f
Where:
• f = focal length (18mm)
• N = aperture (5.6)
• c = circle of confusion (0.03mm for full-frame)
1. Calculate the hyperfocal distance:
Hyperfocal Distance = (18²) / (5.6 × 0.03) + 18
= 324 / 0.168 + 18 ≈ 1946.57mm (~1.95m)
2. When focused at infinity, the sharpness starts at half the hyperfocal distance:
Sharpness starts at = Hyperfocal Distance / 2
= 1946.57 / 2 ≈ 973mm (~97cm)
Answer: With an 18mm lens at f/5.6 focused at infinity on a full-frame camera, the sharpness starts at about 97cm (3.2 feet) and extends to infinity.

It's definitely neat. Not entirely for me -- but I get its appeal for people who travel and want the odd wide angle shot.

That's a great idea. I bet with a distance measuring device and a small engraver you could "fix" the issues I was having with it.

That's great to hear! I knew it was for someone. Thanks for the comment.
5:15 that's bacause you're using a shitty system with no focus peaking. In the Nikon Z we do have that.

@@aaronsambeyfilm on nikon z systems, you can change how picky/critical the focus peaking is.
@wayoutthere907 Yep, also true with Sony. And colour. Brightness. Same with Fuji. Same with Canon.
