The manual lists f4 as minimal for both phase and contrast af. The
600/4 should therefore work. Screwdrive AF can be slower.
If in doubt send the 600/4 to me. I'll run some extensive field tests
and report the results :)

Found a DA 1.4x converter. Tried converters before including the

Combined with the DA300 I can't complain about anything. Tripod test
shots as sharp as can be, no additional CA or purple fringing. Let's
give it a try in the field, handheld...

I'm impressed and saved 2k on a future 150-450. Maybe someday some
serious birding...


I just took a quick look at it at B&H. It says "compatible with Pentax
KAF2 mount lenses on Select DSLR cameras." They've got it in stock
with a "Limited supply" at $$$.ΒΆΒΆ.

I'm guessing the K-1 is one of those select DSLRs, but is the FA-600/4
compatible?

I'm guessing yes, because it works on the K-1 without the rear
converter, but I'd like to *know* I'm not fooling myself before I'd
purchase one.
