Re: 2x extender. Fotodiox or viltrox or save

I have a very, very old Quantaray 2x TC that (kind of) works on an R5 except during bursts where the camera seems to reboot. You do get an error on screen before the reboot but you can continue to shoot. I couldn't tell you if images are lost at that point or if they finish writing to the card.

The converter quality itself is okay, very sharp with a 70-200mm f/2.8 II but obvious loss of contrast. AF locks in but with continuous focus if it happens to miss focus and go to infinity you have to help it come back by turning the MF ring.

I bought my TC more as a toy and I never would use it for anything serious because of the issues. If you can live with those kind of drawbacks, it's serviceable.

It's one of these and I probably bought it for about the same 10 years ago. So a great thing going for it is that if this auction is any indication, it holds up its value well.

I think it behaves similarly with the M6 II but I can't remember if it locks up even worse. At least with the R5, it reboots.
