Yongnuo 50mm f1.4 compatibility with Canon EOS D50 (Er 01)


Does anyone have any experience with this lense and body? Manufacturer says they haven't tested this combo, and I have a problem.

At f1.4, it works perfectly, love this lense, great quality IMO for the price. BUT...

At all other aperture settings, I get Er 01, faulty communication between lens and camera. I've cleaned the contacts (all contacts seemed fine to the naked eye, btw) with a dry soft cloth on both lens and body but the problem persists.

I bought the lens for the wide aperture, but it would be nice to be able to shoot in sunshine as well...

Any help, insight, experience with other cameras with this lens would be much appreciated.

Thank you.
