I bought this TC new in ebay. It has the brand name of both Tokina in the box and Kenko on the TC. I tried it out last night with Pentax F* 300mm f/2.8. The AF actually work in the setup. Though it has the power zoom contacts, it does not work with SDM with my Pentax DA* 50-135mm f/2.8. It is not the best in terms of detail but I get a bunch of clouds moving in with the wind. I will try again in another night

What is your setup in shooting the moon? I cropped the 600mm pictures by about and above 50% in the crop. I lost some detail in the shots but reasonable to use in small size. I will try it again in using just the lens without the TC and heavily crop to view difference
Thanks,
