Does anyone use this converter? am seeking advise on its use with the pentax 300 f4and tamron 70-200 2.8
Tamron 1.4x Pz-AF MC4 is probably the best bet if you can find one s/h, they can be quite pricey. Alternatively the Kenko (Teleplus) 1.5x SHQ and 1.7x SHQ give very good results.

The Sigma 24mm Super-Wide II f2.8 is a fantastic lens, it's one of my favorites. I only paid £30 for mine, and I think it is sharper than my smc 50mm f1.4. It's an A lens so works in AV etc.I have a manual focus one but I believe there are auto-focus versions as well.
Great lens, the AF version in Pentax fit is hard to come by though.

Hi and welcome. If you like primes I think you're going to like owning a Pentax. I have both the DA*200 and DA*300, both fine lenses, I'd advise going to a Pentax Pro dealer such as SRS and trying them for size and weight. The 300 does have a sturdy tripod collar which the 200 lacks, but TBH I've never missed it on the 200.

Maybe it's time to switch to DNG? It isn't any bigger than PEF with the K7.

I use RAW Shell Extender on Win XP, I don't know if there is a 64bit version but it's free. I'd suggest a Google search for RAW shell extender/extension.

I used the same lens with a 1.4TC (Tamron) with no problems. Not sure as to what version lens it was, only borrowed from another member.
1.4x Pz-AF MC4 no doubt, no longer made in Pentax fit but available s/h, at a price. I have one, works really well but suspect it's a Teleplus clone. Works with conventional AF and SDM, not sure about Sigma HSM.
