Originally posted by ChopperCharles I'm looking for an autofocus teleconverter (screw drive pass-through) that will autofocus with my 55-300 kit lens and also be reasonably sharp. Tamron? Kenko? What are my options?
K-x and K-01... but I'll likely mostly use it on the K-01.

You'll run into issues as the TC would make the lens turn into a F6.7-F8 lens or worse, and at those apertures, the AF will not work reliably.
