20 Most Recent Tamron 28-105 F2.8 LD Lens Questions & Answers

I'm surprised it works at all at f/2.8. The FEE indicates that the aperture ring is not at its minimum setting (largest f/number). Turn the aperture ring to its minimum setting. You should be able to control the aperture from the camera body, the same way as on a lens without an aperture ring.

Set up focus point using autofocus, then set camera to manual focus before attaching filter, and be careful not to move focusing ring.

First, I'm not a TAMRON Tech. * Check your warranty and call for service. * Ah, Found this on you tube. (VERY Technical!) https://www.youtube.com/watch?v=o9dvQmVAhK0 * Strongly suggest you have this lens serviced. Aloha, ukeboy57

You'll need to send it to a lens repair service. Do not attempt to disassemble the lens yourself; you'll only make the problem worse and may damage the lens beyond repair.

Use the settings that will give you the best exposure / shutter speed / focus

This is a bit off the wall, I know, but have you contemplated taking the drastic step of getting the lens mended ?

Tele convertors on their own do not focus - that is achieved by the lens. Are the lens contacts clean and correctly aligned with those in the camera ?
