Aa7iii eye af video


Recommended Posts

Hi Everyone,  thanks in advance for your help. I have this amazing A7iii with eye af in photo mode but I’m missing something. Watching all the different videos showing all the amazing features that focus on eye af seem to show that there is eye af in video mode, but unless I’m in p, a, s, or m there isn’t a way to use eye af in video. The other question is do I have to continually have to hold whatever button is assigned (center) or is there a way to toggle eye af. Currently the only way to hold focus is using face detection unless I hold the center button or whatever the button is assigned to for eye af. Great abilities, but frustrated with this. I can’t see holding a button to focus on an eye while the camera is on a gimbal. 

Thanks again for all your help.

Hi LiveShots,

Thanks for letting me know. I actually just updated my camera and new functionality, Face/Eye AF Set. I'm testing it on a 28-75mm Tamron F2.8 and a Sony 85mm F1.8. So at first, the way I interpret "Real Time Eye AF" is that it is constantly focused on the eye without actually pressing anything, so if the model turns away and back, it would automatically re-acquire the eye, but that only happens if you half press the shutter button or press the AF-ON button. So not how I thought it would work, it's still better than assigning a button.

Maybe someone can explain why you only get face detection and not Eye-AF in video mode? If you're doing video interviews, wouldn't that be important?

Thanks,

Robert

I wonder if in video mode you might be more aware of focus changes as the camera hunts for the small eye target, where a face being larger might result in less focus hunting?  Also in video generally your subject is viewed in much less detail as opposed to still photography where you may zoom in and pixel peak just to check focus.  In a talking head video, for example, I don't think one would notice the difference between focus obtained on the eye versus focus on the face.  Just a few thoughts, not based upon fact or knowledge.  (typical for me)

Hi everybody!

So more than one year later, I'm running into this same issue.
I would like to have my Sony A7iii continuous search for Eye AF without having to press the AF-ON button all the time.
It's the same question like Budboy65, especially because my camera is mounted on a gimbal (and even when not, it could be handy, holding a camera when having to press a button, while holding the lens too is hard).

I have firmware 3.01, and still have to press the AF-ON button continuously to be able to have a continuous focus on the eyes.
The only workaround I can see for now is to work with tape and a piece of  cork... but that's not how I think the Sony should work :-)
Any help? Thank you!

Sony a7 III & a7R III do NOT have Real Time Tracking – only a9.

    • That's a pity and certainly doesn't match with my experience with the 18-105: mine is definately on par with the 16-50 kit lens (which on its own was as decent as I could expect from such a cheap lens). Sure, dont expect sharp corners especially wide open, but in the center my 18-105 left little to be desired across most of the zoom range. The 16-55 does beat it in every regard except zoom range though. The Tamron 17-70 trades blows with the 16-55 and might be the better choice in some cases. I went for the 16-55 because of the smaller size (I also found the 18-105 too bulky most of the time) and slightly wider FoV. My camera has a stabilized sensor so stabilized optics was no requirement for me. As you noted, I kept the 18-105 on my old A6000 for the occasional video project.
    • Thanks! The 18-105 mm /f4 was PERFECT lens for my needs but a HUGE disappointed. I bought it with the camera, then I brought it with me on a trip. To my disappointed, all pictures came out slightly blurred, like the lens was slightly out of focus. Stepping down was not solving the issue. The kit lens was definitely better, to my surprise. Thinking that I got a lemon, I went back to the shop where I bought It (luckily, I has bought both the camera and the lens in a brick and mortar store). We tested the lens on another camera and it was the same. Then we tested other copies of the same lens that the store had in stock and all showed the same lack if sharpness. All pictures slightly out of focus. In the end I returned the lens and used the money to buy other equipment. I must admit that it was a perfect lens for video but it is not what I use my camera for. Actually this was confirmed by the shop owner, most buyers of the 18-105 mm are interested in its video capabilities. I will have a look at the Tamron, the Sony 16-55 is almost double the price, at least here, so I will keep it out of the picture, at least for the time being. The Sigma also looks as an interesting option.  
    • Hello ! A friend gave me an old Sony SLT A65 that was locked in a suitcase for some years and guess what... It was pretty dirty. The translucent mirror looks strange. I know it's a pellicle mirror, but something is really weird , at least to me who never saw this entity before. It shows a rainbow pattern when lit, like a diffraction grid. And when I point the camera to a strong light source, let´s say streets lights or car lights, a huge halo and a diffuse pattern appears, almost like one of that photographic filters from the '70s. I guess the mirror is damaged. Does enyone have any experience with this ? I managed to remove the mirror and carefully rinse it with water and detergent solution , rinse again and dry, but the rainbow patter persists. My question is basically about the translucent mirror behavior with strong highlights and if the rainbow pattern on its surface is normal.   Thanks!
