Canon EOS R5

Niestety to musi być sztuczne ograniczenie. Przecież 85 1.8 jest sporo szybszy od Sigmy 105, która też jest EF.

Jednak właśnie owa Sigma 105 mnie ciekawi, dlaczego ona nie ma ograniczeń. Aż jestem ciekaw jak z innymi. Szczególnie 50 A 1.4 bo być może wymienię na nią mojego poczciwego 50L

Jakby co, to jak na razie IBIS nie współpracuje z obiektywem Sigma 50mm f/1.4 DG HSM Art.

IBIS worked great on vintage lenses. It also works just fine with my 24mm and 35mm Art lenses. It does not work at all with my 50mm Art.

Pojawiło się już rozwiązanie tego problemu.

W największym skrócie. Jeżeli coś było grzebane w obiektywie USB dockiem, to trzeba przywrócić obiektyw do ustawień fabrycznych.

SecureGSM: just before you gave up on your 50Art... there are number of firmware adjustable settings that when adjusted may potentially affect lens operation. First off, I would reset All lens setting to default Via USB dock. There is such an option in the sigma software. including manual focus override option set to NO. Reset AFMA adjustment table as well. but P,ease do write down what setting you have now so that you can restore back to if required.

LSXPhotog: You're a genius!!!! I went into the software and reset everything and put it back on the camera and the menu option for IS was now available! Works great!!! Thank you...and sorry Canon, but I won't be buying the RF lens just yet. LOL

LSXPhotog: It looks like reverting the lens back to the original settings (the lens had focusing issues on my DSLRs) fixed it. If I had to guess, the full-time manual override is what caused the problem. I think that setting just allowed you to disengage AF and manually focus when AF is attached to the shutter button...which it wasn't on any of my cameras.

SecureGSM: Great news. Enjoy your 50Art.
