Is this camera prone to not focusing on a bird if it is drastically defocused? This happens with my R5/600iii when the lens’ focus is set very far and then a bird appears very close. The bird is so defocused and the camera picks the background to focus on as opposed to the bird. Anybody seen this happen on the A1?


I haven't tested specifically for this yet but my feeling is that the A1 will have the same issue all of them have. This isn't something you can really fix as the sensor can't see at a great DOF like the off sensor PDAF sensor can in a DSLR (I think I've read it sees at f/22 or so).

There will have to be some different advancement in AF to get rid of this problem. I don't even think that the QPAF of future Canon bodies will make any difference.

Can u please tell us if you are getting 0.9x magnification at 60hz?

I don't see any benefit of using 240hz. The eye point backs out and magnification decreases which sort of negates the great EVF you are paying for. So I've been leaving mine in High 120hz. But even that is probably part of the problem with battery drain.

The only way to get full EVF quality is to put it at 60Hz...but even then as soon as you engage AF you can notice it drop resolution. So you are never getting more than the 5.75M dots for action shooting.

Yes. Anytime the EVF is not showing any obvious black outline it is 0.9x. I only see it go to the zoomed out view with black borders if I switch to 240. Before getting the camera I thought I had read that going to 30FPS also zoomed out but it doesn't. There is also the setting in the menus to put it in the zoomed out mode if you prefer it (if you wear glasses it may be preferred).

p.7 #4Sony A1 - Bird Photography Camera for Dummies
One weird thing I run into today is that with EVF on high quality and AF-C using Sony 50 ZA I saw only a brief resolution drop when focusing (think like in AF-S), even though the focus points were indicating a near constant lock. When I tried the same the other day with Sigma 35 f1.2, the resolution dropped for all the time I half-pressed the shutter to acquire focus.
Not sure if this is a coincidence or if the same can be observerd on targets requiring more demanding continuous focus (I used a fairly static computer screen for this test ), but it would be a big advantage over 3rd party if Sony native lenses could minimize the time the EVF resolution drops during focus acquisition in AF-C.

I just tested my Sigma 35mm f/1.2 and I didn’t notice what you described. It is semi dark already although my windows are open, the room was mostly lit with indoor lights. I will play with that some more though and will report back later, probably tomorrow.

Thank you Geoff. I think I should really see what it's like. I wear glasses. Even after using a9 for couple of years, I still can't get used to EVF. One of the headline features for me was the .9x viewfinder. If I can't get it (with glasses) it'll be disappointing.

Thanks. I tried again and I think it depends on how sensitive the lens is in regards to focus in AF-C. If the lens is constantly doing micro-adjustments, then the resolution drops (but you need something farily detailed in the EVF to see the difference, that's why I used my computer screen with this forum displayed, but any text would work as well ). If the camera believes the focus does not need any adjustments, the EVF keeps its high quality display...

I was just noting that after I changed the sleep from the default the first day when I had the problems to 5 min and went back out yesterday for 4 hours, it did not happen. Having a longer timeout does reduce the number of times it will go to sleep, so there may be something to that.
Although it could be related to a number of other things, too.

Thanks for 're'posting this. I was looking for this info. In your opinion what gives better EVF experience? 60fps and 9.44m dots or 120fps and 5.76m dots? Assuming fast action is the only thing I care about (BIF). I think I'd like .9x magnification.

Interesting. I noticed this annoying behavior with A9 and thought I was doing something wrong. I usually point the camera to ground to focus closer and then aim at the subject.

You can't get 9.44M for any BIF no matter the setting because as soon as you initiate AF the resolution drops even in 60hz. 60 Hz is not good for fast moving things. Like if you are watching a hummingbird feed at flowers through the EVF, waiting for it to move to a better flower you often won't see it move in the EVF, will have to take your eye away from the EVF to find where it went and then get back on it (often too late). At 120Hz you usually can see it move in the EVF and get on it fast at the new flower.

Thanks you Geoff. So 120/5.76/ at .9x or .78x is the option for BIF. With glasses I might have to zoom out.

I think A9 has 3.7M dots and 60fps for continuous shooting. I have to try it out to really understand the difference.

Yes and the A9 is where I have more experience trying the 60Hz. That is where I noticed my hummingbird issues. The A9 probably drops to 2.X M dots the way I shoot it in Higher refresh of 120Hz.

I've now found two things that I consider "broken" on the A1 The second is when I run my EVF/LCD in pseudo DSLR mode it doesn't show me the exposure changes I'm making at the bottom of the LCD like it does on the previous cameras. That function was my workaround for not having a top LCD. Unless I'm missing some setting...I will investigate further.


Do you not run yours with the EVF showing real time exposure? I have been and not sure I like it. If you aren't how do you set the EVF brightness? Auto, manual?
