Studio settings?

[MickPayton]

Has anyone else found that with the A7R4 in the studio using flash, there's a significant delay in the shutter when using AFC and eye AF with tracking? The same setup in ambient light has no delay?

Using AFS Single point, no eye AF, in the studio with flash, there is no delay.

A novice's wild guess would be - if using a high-end Sony flash, it will take a few extra milliseconds delay factoring in AFC and flash TTL calculations for proper exposure combined before shutter response.

that seems like a pretty solid novice guess.

I'm not really sure why anyone would use a Sony flash and TTL in the studio, but I guess should have made it clearer, this was using Elinchrom flash in the studio. Problem solved now with further experimentation, the combination of eye AF on the shutter button and EVF off produces this odd delay effect - for me anyway - so, allocating eye AF to the AE button has fixed it, and to be honest I prefer it set up like this now I've used it for a while.

that is weird. Wonder why...

thanks for closing the loop!

Absolutely no idea! Even Sony have no answer.

I've recently switched to the Sony A7R IV from Fuji, so am still getting used to it. I'm finding autofocus difficult in studio. I use an Elinchrom D Lite One and octabox, 24-70mm GM lens. The pic below is taken at f7 200/s ISO 100.

I'm also struggling to see how to focus in a dark set up. I have the modelling light on, but looking through the viewfinder, I can't see a thing unless I depress the shutter halfway. What am I doing wrong? I can't see how to see! Any help greatly appreciated. Thanks.

Hiya, you will need to turn the live view evf off in the studio. What focussing mode are you using? For most people shots I use eye AF with AFC, if this is not suitable I'll use single point AFS. I have shutter button focussing turned off, focussing set to AF button and eye AF set to AEL button, this gives me a lot of flexibility with focussing as I can switch from one to the other just by moving my thumb. Autofocus in the studio is very fast when it's set right.

Great, thanks for the advice. Yep I'm using eye AF with AFC. Will try the different use of back buttons.
