I've not really put any of them through their paces yet. (and I've had the Kenko adapters for years, and they're even auto-focus.)
I also have an old-school macro bellows.. but that isn't tele.
I do wonder how many folks have teleconverters instead of super-long lenses. I guess we'll see, and maybe I'll try to shoot a few things worthy of posting with my tele's.

My longest lenses are 300mm, including an A*300/4 and a DA 300/4. I use the T6 2x on my K 200/2.5, the F 1.7x AF on the A*300 (to give me auto focus) and the DA 300 by itself. This give me an economical 400mm, a fairly economical 510mm and an exquisite 300mm.

How do you like the DA 300 + 1.7 AF combo? I've never tried it since the DA is such a superb lens by itself. I find the 1.7x AF with the A*300 to be a great combination. I'll have to dig up some photos from this setup.
