Yesterday while I was doing nature photography I had to turn off the camera several times because it was hanging with the curtain up, nothing was visible on the display and in the EVF you could see the last photo shot and the focus points were blinking.

The problem was presented with the following configuration

Sony A7R III + Metabones V + Canon EF 400mm f / 5.6L USM AF-C Wide focus mode

 

Did any of you have a similar problem?

 

`   

   

That EXACT problem ? Maybe someone has that

one exactly. My experience is less drastic. But if 

there was no permanent damage, then this also 

hardly rates as truly "drastic".

 

BTW how did you confirm the curtain was actually

hanging ? OTOH, you've described just one more 

version of the Canon-EF-on-Sony bad dream. It's 

possible that you need one, or more, FW updates,   

up to three: Body, Lens, and Converter.    

    

-----------------------------------------------------------   

   

I've returned more converters than I've kept. Thaz 

how it goes. As to updates, I personally don't ever 

bother cuz I'm not deeply committed to a bad idea. 

Frinstintz, I've got a pair of a7-II at different levels 

of FW. One works OK with some EF lenses while 

the other is near to hopeless.  

  

If you expect your EF-plus-E-Mount rig to operate 

as a fully effective primary rig, rotsa ruck :-( OTOH 

it's a lottery and there are occasional rare winners !

You never update firmware? Congratulations, you just became Sony Dream Customer #1.

 

To the question, I suspect the adapter needs a firmware update for the new camera. Whether it is available yet, I don't know.

I got the camera, the lens and the adapter about a month ago, at that time I updated the available firmware.

The version of Metabones available was 0.57, now I updated to version 0.58 that came out soon after and apparently works well.

I did about 1000 test shots without news, but I'm going to check out the camera when it stops raining.

I only use this type of shot for birds in flight since otherwise the rolling shutter is very annoying

 

Thanks a lot
