- Vivitar 2x MFTC
they all work just fine.
The AF works too.
The combo of 43 Ltd & Vivitar 2x Macro TC is just amazingly sharp, much sharper than the TC with my FA 50/1.4 or even F 50/1.4.
Since the Limited shares the same technology, I'm pretty sure they will work just fine.
Nope, talking about this TC:
Pentax Lens Review Database - 1.4x-S
Thanks for your comments. I've used it on A50/1.4 and it's nice (eff.70/2).
TC's work best on fast tele primes, so I don't see why it wouldn't work on the 77/1.8.
It would be a very compact and versatile combo, compared to carrying both a 77/1.8 and a 100/2.8.
But there are just some lenses that don't TC well and others that do, hence the question.
