Tokina 12-24mm f4 design fault
In reply to BobT, Jun 18, 2012

My Tokina first started to give lens errors when trying to stop down between 12-15mm (the first symptom). After a while it got its aperture stuck closed at around f10 (estimate/guess) while it thinks it is open. It will actually close more when you select more than f4.

I found out this was not an isolated problem, but a symptomatic problem for a design fault of this lens, and that Tokina plays oblivious about it and only fixes it when you pay for the "repair" yourself.
