Very informative. But doesn't this depend also on the way the auto focus is setup in the camera (single point or zone)?

I'm just going to add that you should also take in consideration lens diffraction when using higher apertures.

Thank you for the interesting test. 😊 I thought F8 focusing on the background would give a bit of blurriness in the foreground, but it gave the sharpest image. I am puzzled by the results.😆 I'm gonna practice using mid-aperture F8-F11 with a focus on a subject in the background and foreground. Have a nice Friday and weekend :)

Going above f10 on my 5DmkII results in increasingly soft images, due to diffraction.

But what did you focus on in the auto focus example?
@TheCameraManReviews

That is a very good question, and I should have highlighted that more in the video. I left the camera in Auto-focus, wide, single shot mode, (What someone new to cameras would use) so that the camera could literally decide for itself what to focus on. And as you saw it missed focus completely. Which even I was surprised with. 99% of the time it would have hit something, which makes me think a bird flew past as I pressed focus, or maybe it did just miss. If I was to use selective area focus, I am sure it would have hit and competed with the manual focus. But I personally would still manually focus on the furthest object in scene if you looking for infinity focus, or even better stack focus.

I have some problem with wide angles and infinity autofocus. Autofocus on near subjects are absolutely perfect and sharp. With normal and long focal length focusing is perfect. But.. If I use a wide angle like a 24mm and I focus on a far subject like your tower I'll take a no sharp picture. I've got a Canon 7D mk2. I tried with more lenses... so the problem is the autofocus on infinity together the wide angle lenses.

There are so many varieties with setting auto focus. I think you could make an entire video on the best way to use auto focus, depending on the composition. Your use of it here wasn't fair or accurate.

8:10 The f/8 is clearly sharper. At f/16 diffraction becomes an issue on APS-C so one should avoid it.

It was very interesting and at least entertaining. But a little bit hard to believe. In my consideration now, let's say that we start with the image that you found to be sharpest (and also the foreground was sharpest?). Then (theoretically at least) follow up with a new series of images where the only change from image to image is that you focus a bit more closer. So you start with focusing on the towers. Then focus a little bit closer and closer and go on like that until you focus on the bush in the foreground. Do you think that the sharpness of the bush in the foreground, judged from image to image in this series, would be sharper through the series? I would certainly believe it. But I wonder if what you showed and claim in the video is different(?). Maybe for particular lenses they can have anomalies and behave different than regular expectation. But in general I find it hard to believe that focusing further away from something (the foreground) will make it sharper. What have I misunderstood?

you still using auto focus on the second shot (1/3). You’re just manually selecting your focus point. Am I understanding that correctly?

Is the sharpest aperture f.8 also apply to my 4/3 lens?

It normally is middle of the lenses aperture range, and would be the same on 4/3. Basically u can't go wrong with middle of aperture range.

if you are going to show comparison between the photos they need to be in line... F8 & F16 pics, 8:31 in.. are well out of line..........if you are going to show people comparisons do it properly.

Why don't you just zoom right in on things, like the towers, so it's far easier to see the difference?.. There's no way we can see any difference unless it's zoomed in a lot more.
@viktorpaulsen627

Did you take only one photo with autofocus? And no part of the image was in focus. I would say that this is not statistically significant. One could not draw any conclusions from it. Maybe the next 99 shots would be in focus, at least at some place in the image.

Haha Infinitity at 3 miles? never ever!!!! sir real infinity at 8km!!! you must find a tv-tower with sharp edges. 200mm lens is enough. NB: old lenses on digital dont reach infinity. adapter must be shorter zeiss confirmed. dont ever think about using K+F comfort Nikon or EOS they are too long evern not reaching register but they must even be a bit shorter than register otherwise not perrfeclty sharp images. F8/f 11 best on aps-c. P67 200 new. Novoflex adapter system goes beyond infinity. so their older noflexar 200/3.8 follow focus. i made variable register adapter for P67. yes one needs a collimator-tested lensfor comparison to really find out where the problems are.
