I got a Sigma Art 35mm F14 FE mount and it worked for a while.

But then mysteriously the aperture no longer responds to controls and is stuck at around F16.

I thing there is a more recent firmware upgrade but you need the dock to install it.

Any suggestions? I guess I send it back for repairs.


I don't suppose you have another E-mount camera available to test it with?

As for dock, I don't think there is an E-mount dock; if fw update for an E-mount Sigma lens then via camera, as far as I'm aware. Edit - assuming this is the DN version, that is the native E-mount one, if not then there still is no dock. Would be a dock if you had purchased the Canon version.

Yes it is the Emount version. Good advice, I realised y wife has a Sony 6000 camera so I'll try the lens on that if it fits an APSc camera.
