Using Green square Eye AF using Manual Focus, possible??


Recommended Posts

It's not possible: that green square is an autofocus-confirmation box. If autofocus is disabled, the camera is not searching for eyes/faces so there won't be any green boxes. Focus magnification on the eyes might help in your case, though you need a model standing fairly still for this to work.

I think not. The eye focus belongs to the AF system (it works automatically if activated).
The focus peaking is a great means of assisting manual focusing in my opinion and can be used and be effective for most subjects. It will highlight vertical lines (or almost vertical) being in focus if the camera is horizontal, and horizontal lines if the camera is in portrait (vertical) position, so one can turn the camera to whichever position would be better to focus manually (even to a diagonal position) and then turn it back if necessary to the intended position for the photo (portrait or landscape).
I have recently bought an a7 and in order to get further assistance for manual focusing, I have also set (assigned) through the menu the Function Central Button to activate (at will) the Focus Magnifier (the digital zoom magnifier).
If being convenient, for AF mode, I can reassign the same Function Central Button to activate/deactivate the Eye AF (I did not set the camera to have it permanently activated, as I prefer not to).

But it's not possible to use this feature using old vintage lenses.. it's really annoying cause i'm sure that the camera can recognize the faces en the eyes.. It'would be very helpful something like that. isn't it?

Automatic magnification on turning the focus ring (MF assist) might not work with a fully manual lens, but you can map a custom button to trigger magnification. Personally I really hate the automatic magnification: the camera doesn't know where you want to focus so the magnified area is always off, plus it messes up your composition while trying to do preliminary focussing.

I use focus peaking for coarse focus setting, then I magnify on the spot I want to focus on using my custom zoom button. The big advantage of using a custom button is that you can first determine where to set the zoom box before actually zooming in. I feel much more in control of the composition and much less disturbed by the focus magnification if triggered manually.

My camera is set to back button MF as standard. However, I have set C2 to change it to AF mode. After having pressed C2 it will stay in AF mode until either C2 is pressed again, or the back MF button is pressed, or the camera is turned off. For me this allows the best of both worlds.

I use C2 to magnify.. since 3 years.. it's comfortable,but not quick as it should be.. then move the area with joystick or the "touchpad" is very slow too.. focus peaking is not so reliable. 

Can you imagine how can be easy to snap the magnification on the eye or on the facet.. SONY!!! WAKE UP! ADD THIS FEATURE 😅!

    • Hi there. I have a similar issue with my ZV1, I think? It's annoying - to the point where I'm wondering if I a have a fault with my device and am considering returning it under warrantee. I use it to film yoga instructional videos. They are sometimes 90 minutes long. I know that inorder to run for this length of time, the camera needs to be plugged into the mains. So I plug the camera into the mains and double check that the mains charge is showing - the battery icon confirms this : it has a little plug symbol beside it. So - I should be good to go. However.  The camera still turns off after an hour or so, saying the battery is flat. Interrupting the filming. Which ruins the whole video. At that point, if I go back to the camera now its battery is flat and pull out the charging cable from the mains and put it back in again, I can continue recording for 90 minutes plus as required. My issue is: the Sony ZV1 is not using the mains while the battery is charged. It continues to run on battery power. Then switches itself off (infuriatingly). And then - only at that point when I plug it in again and turn it on again does it start using the mains as it's power source. I'm 99% sure this is what is taking place but still on a learning curve are trying many workarounds this problem... not of which have been successful yet. I'd really appreciate some help with this. The next thing I'm going to check is deliberately flattening the battery before I start filming. But this seems a clumsy workaround. Otherwise - absolutely loving this camera! A huge improvement on my old camera. But only if I can RELY on it! Best wishes Frances  
    • From direct comparison on an American site and from what I can tell from reviews, it looks like the Tamron F2.8 SP Di USD will be my choice over the Sony. The optics appear to be very similar, but the Tamron's USD focussing appears to be quieter and as quick (although not as accurate in low light). So the main factors for me are: Apparently the Sony was optimised for cropped sensor, although advertised for use with full frame as well.  Weather sealing (Yes on the Tamron, no on the Sony) and the colour of the body is more discreet - and, of course, it's £100 cheaper. If the Sony SSM II was in my budget, that would be a different story. Anyway, when I've taken the plunge I'll let you know if I'm happy with the choice!
    • Just an update to this, I have updated to firmware 1.02, but I get still get the 2nd base ISO at 10000. It seems that I have the only A7Siii in the world that does this😬😬
    • I got a new Sony RX 100VII but I will keep the 100II. I have been looking into the specifications of both chargers but didn't come to a conclusion. Since teh batteries and the same, can I use the charger of the most recent camera to charge the old one ? Thank you !  
    • I have this problem as well. Glad to see I'm not the only one but it appears like this is a common issue. Sorry to respond 4 years later but I'm hoping to resurrect this now to see if there's been a solution since 4 years ago!
