I don’t get how this can be the case on a camera costing this much… Does it have a slower 60fps mode that doesn’t drop resolution? Yes it does, not dramatically but clearly. And another one thing that only few mentions. Absolutely a show stopper for me for example in studio work. Tried last friday with 1 year photo shoot and at least I cannot see clearly if he/she is starting to smile. EVF is "blurry". And it's fine in everyday shooting but in critical studio work well at least for me no go. Even in ice hockey, I use SL2s because I can see clearly what I'm shooting. And I get it that this does no affact to some, but I find it very strange. Edited March 31, 2024 by Mikko Kankainen 1 Link to post Share on other sites More sharing options...

But I agree the EVF experience and overall performance in AFC is not what you would expect from a 7k$ camera in 2024. 2 Link to post Share on other sites More sharing options...

It is however blurry, you have to trust that camera has locked focus, you cannot see clearly.  And every professional knows how important it is to see clearly every detail in persons face. At least I cannot work in afc in portraits so it’s contrast focusing for me. Edited March 31, 2024 by Mikko Kankainen Link to post Share on other sites More sharing options...
Dr. G Posted March 31, 2024 Share #86  Posted March 31, 2024 Someone mentioned otherwise a few weeks ago (I have to find the post), but wouldn’t it make sense for focus to take priority over shutter release in AF-C?  Meaning if you depress the shutter in AF-C, shouldn’t the camera not capture the image unless focus is obtained?

It may be different in professional circumstances, but I rather have the right moment over perfect focus for people shots, if I had to chose. Link to post Share on other sites More sharing options...

I don’t get how this can be the case on a camera costing this much… Does it have a slower 60fps mode that doesn’t drop resolution? Unfortunately this is an issue with all cameras that use PDAF based AF.  My Sony’s (A1 and A7rV) exhibit it.  I’ve also seen other camera brands have the same issue.  However some do a better job at reducing the aliasing and fuzziness than others.  Still don’t know why it’s tied to the AF system but because I see it in other cameras it’s no longer a show stopper for me.  Have to live with it or work around it.  I do believe Sony’s A9 III with global shutter seems to have fixed it.  Maybe a combination of shutter and processing? For studio work I plan to use M lenses and focus manually which will keep my EVF clear. 3 Link to post Share on other sites More sharing options...
sebben Posted March 31, 2024 Share #91  Posted March 31, 2024 @petereprice sounds like the Nikon Z9 and Z8 fixed this by using a lower resolution evf and a different sensor design.   1 Link to post Share on other sites More sharing options...
jaapv Posted March 31, 2024 Share #92  Posted March 31, 2024 This is the S5ii on AFC. I was going to post all 24 test shots I did that day, using the Sigma 150-600 but it got boring as there was not one shot OOF. Totally random selection, mainly in burst mode and zooming. (Human/animal recognition, Field.) I fail to see what is wrong... Welcome, dear visitor!

S5ii consistently misfocus eyes about 10-20 cm when using Sigma 70-200 @f2.8 and at 100+mm, and in high speed mode. (Similar with other lenses). At f4-5.6, things are ok. SL3 is better at finding eye focys, but limited to 4 (or 5) fps in AFc. Edited March 31, 2024 by helged Link to post Share on other sites More sharing options...

When looking at Sony and Nikon low/high resolution offerings (Z7 vs Z6, a7riv vs a7iv), there does not seem to be any relevant difference in focusing speed and accuracy. 2 Link to post Share on other sites More sharing options...
