luisdent Posted August 1 Share #1 Posted August 1 Advertisement (gone after registration) I just got a q3 28. Love it. however I'm a bit confused. The evf is rated at a much higher resolution than my xt5. But compared to the xt5 with 18 1.4 (similar fov) the difference in evf is so much more noticeably than i thought. Focused properly on a set of books at a distance, the xt5 is clear as day. The q3 isn't even legible. The text on the spines looks like a pixelated mess. Relatively speaking it's isn't night and day, but looking carefully it's the difference between legibility and not. And it's simply visually not clear for judging sharpness. It gets even worse when half pressing to focus until you release again. This happens even worse at 120hz. Lame. Tried changing a bunch of settings with no change. Got the camera on firmware 3.0. updated to 3.1.1 and no change. Is there no fix for this? It's literally worse than the xt5 despite better specs. But the screen itself looks ok as the interface elements are super sharp. So it appears to be a software issue. Especially as 120hz makes it worse. Is there any resolution? Pun intended.

Tarekith Posted August 1 Share #2 Posted August 1 Try adjusting the diopter on the back of the Q3, mine wasn’t set correctly from the factory and I felt the same as you until I adjusted it. Link to post Share on other sites More sharing options...
luisdent Posted August 1 Author Share #3 Posted August 1 Sadly i tried that. And as i mentioned the interface elements on the screen look sharp (and become unsharp shen i adjust the diopter) so this appears to be something else... Link to post Share on other sites More sharing options...
Le Chef Posted August 1 Share #4 Posted August 1 (edited) Switch the EVF screen refresh back to 60Hz. Are you sure the lens is clicked into place for autofocus? Try the lens in manual focus to see what happens. Also shoot an image then look at It on your computer screen. Is it sharp? it’s a silly thing but did you pull out the diopter adjustment and turn it?

luisdent Posted August 1 Author Share #6 Posted August 1 (edited) Okay, so here is what I have found so far. It is 100% a software issue. It is the intelligent autofocus setting. It is also the 120 hz setting. If I use 60 hz without the intelligent autofocus, it looks perfect. If I use 60 hz with intelligent autofocus it looks fine until I press the shutter halfway to focus and then it drops into a low resolution rendering. When 120 hz is enabled that low resolution rendering is all the time both in and out of the focusing half press. So sadly, for me 120 hz and intelligent autofocus are both big no-nos, as it literally makes it hard to tell if something is in focus when you have press the shutter. Not the biggest issue, I will try to use 60 hz, and I prefer AFS anyway. But just something to note. I assume the camera is allocating more resources to the autofocus and the refresh rate and taking them away from the resolution in those settings. That seems very odd as the Fujifilm XT5 can do 120 hz and all the autofocusing it has with no issues, but I digress... I'm just not sure what benefit 120 Hertz and autofocus settings have if they prevent you from seeing the focus clearly? Maybe they could be fixed in a future firmware update, but these issues seem to be prevalent on online forums back to previous firmwares...

F-train Posted August 1 Share #7 Posted August 1 Advertisement (gone after registration) I tried to reproduce it with my Q43, but see no change in EVF resolution as you mentioned. With all combinations I can check focus. Link to post Share on other sites More sharing options...
Le Chef Posted August 1 Share #8 Posted August 1 Dump the unintelligent focus - it’s useless. It also doesn’ work in RAW. 1 Link to post Share on other sites More sharing options...
luisdent Posted August 2 Author Share #9 Posted August 2 I did a lot more research in this appears to be a fairly normal occurrence on cameras with large sensors. It is a bandwidth bus limitation. When complex processing is done the EVF resolution is decreased so that the data has enough bandwidth Some people may not be as sensitive to this, but apparently this even happens on the flagship Sony cameras. Ironically many of those have the same 60 megapixel sensor, as leica uses a Sony sensor. So I would assume this appears to be completely normal operation. Either way I've reached out to Leica and we'll see what they say. perhaps they can clarify this. pun intended. 2 Link to post Share on other sites More sharing options...
luisdent Posted August 6 Author Share #10 Posted August 6 For the record i got a response from Leica support, and this is completely normal. They recommended 60hz and af-s for the best evf experience. Iaf and continuous af and 120hz all reduce the resolution. This is most noticeable on things that produce a moire pattern. So if you see this, at least take solace knowing it is normal. 1 Link to post Share on other sites More sharing options...
