Hi,

My Metabones mark IV works some times, ome times not. Reseating the lens sometimes solves the problem, sometimes I just give up.
What happens is that the camera doesn't connect with the lens. The adapter is seen but the lens is not.

What is your experience?

I am using a Sony A7rII and a 24/3.5 TSEII, but I have also seen the issue on a 16-35/4. All stuff tested is brand new. I may get another one and claim warranty on the one I have. But repairs can be tricky on intermittent problems.

Best regards

your equipment is brand new , if faulty metabones should replace the adapter free of charge.
If you've bought via credit card/ paypal you'll also have buyers protection.
you may need to be persistent with emails, they don't always respond immediately but usually come through in the end.

btw, i think there'll soon be new firmware released.
Hope it works out.

Hi,

Yes, I am aware of it. The problem is that warranty doesn't help with missed opportunities. I am pretty sure it will be resolved to my satisfaction, in due time, but I will loose a lot of shooting oppurtunities meanwhile.

What also concerns me is the intermittent nature of the problem. Sometimes it works great and sometimes not at all.

So I consider to buy another one, and than sell of the other one. Anyway it would be nice to know how many users have problems.

Best regards
Erik

Mine (just purchased from B&H, firmware 0.41) always recognizes the lens, but have intermittent problems with auto focus on a7r2 (which will presumably/hopefully be fixed when firmware 0.42 is released).  Metabones says release of the updated firmware is "imminent".

[Hywel]

Mine is a bit iffy. Sometimes I can't get it to mate with the lenses well enough to control aperture, other times it works fine.

I wouldn't rely on it for professional gigs, frankly.

Cheers, Hywel

I would say time to start a new poll specifying firmware 0.43.  I had problems with 0.41 and a7r2, now completely resolved with 0.43 firmware.

Hi,

My problems seem to be more of a hardware problem than a firmware problem.

I thought mine was a hardware not-making-contact problem but the new firmware has completely transformed the situation and it is now working flawlessly even with very old lenses using PDAF very fast, and I've not seen the aperture/lens not making contact problems since I upgraded. OK it has only been 24 hours but I spent all day and night out in the mountains shooting and it genuinely seems to have fixed all the issues I had.

So I'd definitely try the new firmware first and only then start looking to hardware.
