Yeah that's bad news. The first copy of mine couldn't do eye-AF properly even under ideal conditions. It really is a gamble at this point. I'm still waiting for my 3rd copy and I'm not confident ...

Why is that?

My second copy of the A7III did not have any eye-AF issues. I didn't test it at near MFD distance purposely—I never shoot 85mm at MFD with a human face anyways. However, the photo of me I attached ...

On the eye? Yeah, it's because the lens isn't calibrated properly so the focus was off. The one thing I hated most about DSLR is that I always had to worry about calibration.

Actually??

Oh me too! I'm a fan of Tamron's pro lenses. I owned their 45mm f1.8 SP and it was a spectacular lens. Not a big deal to me at all. I sometimes found 24mm to be too wide. I never use the button on ...

Nothing! It's an amazing lens! It's just that with the Tamron 28-75 coming, assuming it has the Tamron SP quality, the GM is just simply not worth 3 times the cost. Maybe the Tamron lens it's not ...

Dustin Abbott is absurdly underrated on YouTube. His lens reviews are some of the best in YouTube (I would even venture to say they are the best).

I personally don't think even with all these arguments added up, the GM is worth 3 times the cost. This is the territory of diminishing returns. You can get a great quality WA prime in addition to ...

You simply have the wrong expectations with his video. I agree it's pretty useless, but right from the beginning, it is more like an unboxing video. His actual in-depth lens reviews aren't like this. ...

AF-S? In my case, AF-S works with the good copy. It's just that eye-AF seems to work the best with AF-C cuz it tracks the eye continuously.

That is correct. I have reiterated multiple times in several of these eye-AF issue threads on how to go about testing your camera. Simply get a fast prime (anything slower than 2.8 won't do), and ...

I used to shoot portraiture only and I had only one prime, the Tamron 45mm f1.8. I never found it limiting at all; I guess it's because I always focus on what can be done with my kit rather than what ...

I don't agree with this advice. A7R3 doesn't have some of the features that A7 III has (and vice versa of course), such as 93% AF coverage and 6k to 4k recording. To a hybrid shooter, for example, ...

Honestly that was my thought too. Just look at the eyes below, one is Asian (mine) and the other is Caucasian. The latter has a much deeper socket. It's fascinating how differently they are ...

This has been said many times. I encountered eye-AF issues at farther distance too. Check her right eye in this picture; the eye-AF green box was on that eye.

Ask yourself these questions to see if you want any of the exclusive features that the other camera doesn't have. Do you need pixel shift? If yes, A7R III. Do you need 93% AF coverage? If yes, A7 III.

Ah that makes sense.

Sure, but it happens with iOS too. Software bugs simply don't always manifest on all devices, not even on the same models. Some bugs do though. Maybe it's the way the employees install the FW in ...

I wrote a detailed report to my local rep about the eye-AF problem; he reported it to Sony and he said Sony told him that it's a software problem and they are looking into fixing it. I can provide ...
