F00

My new R5 just arrived.  I had to buy Vello adaptor as the Canon brand was out of stock.  I put my 24-70L on the new camera, everything works great.  I them tried my 70-200L, I get an F00 for my apature.  I put this lens back on my 5d iii and it works great on it.  I cleaned the contacts, remove the battery for several minutes.  Anyone have any other suggestions?

Throw away the adapter?

Re: F00

So you think the adapter is the problem?  It works fine with other lenses.

What else could it be? You might see if there is a firmware update for the adapter. I think it has to respond differently depending on the lens attached.

That makes sense.  Im going to return it and see if I can find a canon adaptor.  I cant afford to buy all new lenses right now.

This seldom to never works or helps.  You can in fact damage the contacts if done incorrectly.

I know the feeling. I laid off buying the R6 until I could get the ring type adapter for my EF lenses. If you can afford it, spring for the ring adapter. It puts a lot of control at your fingertips. No one had one for the longest time, then Canon suddenly had one in their store and I pressed BUY quick and in a hurry Smiley Happy

Yeah, it sounds like the adapter.  If you can get the Canon mount adapter then do it.  

 

Vello usually makes pretty good gear.  I would contact them about it. Remember, this is a mount adapter, which means it stays on the camera body, unlike a lens adapter that stays on the lens.
