Hi Guys,

On a shoot in False Bay right now and I am experiencing a problem with my Tokina 10-17. Would appreciate some input:


My images are about twice as bright at 10mm than at 17mm. So when I set exposure at 17mm and zoom out, it blows out all the images. If I set exposure at 10mm and zoom to 17mm the images are practically black.


I've tried it on 2 different D7000 bodies and its doing the same thing so it is clearly the lens. I can keep adjusting the exposure but its very frustrating. Any ideas?

The 10-17 is really wide at the 10 end. Are you sure that you have your strobes well behind the camera and that is not your problem? The strobes need to be totally out of the picture so the strobes need to be further away from the subject than the camera. Aside from that I have no other idea but posting some sample pictures would probably be advisable.

Thanks Bill. I've been using this lens for years and its definitely not strobe position. If I posted images you'd see a narrow angle well exposed shot followed by a wider almost completely white shot. I am just curious how the length could make such an enormous difference. I'm assuming its a circuit board issue in the lens but I am not sure if the lens even transmits exposure data to the camera or if that is all registered by the body itself.

You could have an issue with the aperture motor.  I sort of had that problem with my 10-17 a while back and Tokina replaced the whole aperture assembly.

What metering mode are you using?

Try different modes at  at 10 mm with out changing any other variables..

I shoot the 10-17 on my D7000 bodies without any issues like that. I have a feeling it's a lens issue, not a user issue.
