I am not desperate to get one of those, but is on my wanted list. is the pentax branded ones still taking the lead? i prefer a X1.4 or 1.5, but they seem to be very rare and expensive, so maybe realistic to pocket a X2 teleconverter. which one is worth watching?

Thanks

The KT6 and 2x A are worth watching.

I have a mint Pentax 2x A for sale.

I used to use it with the M*300 and FA*400.

PM me if interested?

Why not buy a 1.4x or 1.5x AF one, it will work perfectly well in MF?
Plenty to choose from and relatively cheap.

What is KT6? Why is the 2X A without SMC marking?

a 1.5x or 1.4x is ideal, just losing one stop. but it's hard to find one for pentax with a good optical design. F 1.7x seems really nice, but the price has gone up the roof.

It's SMC but earlier K, M series lenses.

Teleplus, (Kenko) 1.5x are very respectable IMHO, various clones on the Teleplus design exist.

Im pretty sure there is a Pentax A rear converter S which would suit you but they are pretty rare.

You did say you weren't desperate though

MF in the heading, does that refer to Medium Format?

In this case I think he means "manual focus" as in the "mflenses" forum. As acronyms go MF is one of the more ambiguous ones.

I wonder if there is a mfmflenses forum....

Lots of film bodies, a couple of digital ones, too many lenses (mainly older glass) and a Horseman LE 5x4.

Spot on.

I did see one of pentax x1.4 for sale on ebay. it ended around 60 quit. it's marked with SMC or in PKA as far as i remembered.

Pentax used to have some 'takumar' lenses, which were the cheaper alternatives and the optical quality were not in line with the SMC versions.
