Sigma 24-70 f/2.8 DG lens giving Err 01 on Canon R5

Hello! I just picked up a used Sigma 24-70 f/2.8 DG OS lens (the newest 24-70 version, 2019 I think?) and it works just fine on manual focus, but the AF is not working. It was giving me an Err 01 code, and so I researched and found that the most comm...

EF-S lenses on R10 with adaptor: Does cropping occur?

EF300mm F/2.8 II concerns about service ending in 2028
