I have the older but fabulous Contax Zeiss 85/1.4 (is this optically identical to the ZK ? I believe it is but may be wrong) and the Pentax 77 Ltd. They are, as Byrd says, completely different animals. I use the 77 Ltd a lot of the time and rarely the CZ .... but I still wouldn't sell it (and in perfect condition it only cost me ca. US$680 pus another $50 for the PK mount conversion) as it is unique. BTW CIF works wonderfully with those MF lenses.
I've tried the Sigma 85/1.4 vs the 77 Ltd. The Sigma is very sharp, very fast AF and a lovely (if heavier) lens, it has received superb reviews. However I found the CA is worse than on the 77 Ltd and the rendering is very different.
Rikenon / Bower (and under probably a dozen other names) 85/1.4 is amazing value for money .... but why buy this if you want the best/better and have the money for it ?
The Pentax A & FA lenses are waaay over-priced. Of course a lot of that has to do with their rarity (though there are plenty of the FA versions where I shop) and not just how very good they are.
For the OP. Sorry to say but those low-light photos you've posted wouldn't hold up in print, for me at least they wouldn't be worth it. Maybe the AF of the 77 Ltd would give you far more keepers ? Check out the FA Limited thread here on PF for hundreds of scorching shots from the 77 - the bokeh of which is just gorgeous BTW.
IMHO - get the 77 Ltd and the Sigma 30/1.4 (another superb low-light lens) !
Thanks for the extended info. The previous post you quoted was one I did pay direct attention too.
Yes, the low light photos are not good enough for print. The first pairing were the first ones I could find, and they are from my k1000D when I first started shooting digital. The second pairing were downloaded from Facebook as I can't seem to find the original RAW files, so they are compromised quite a bit. They are also a few years old and my skills have jumped quite a bit in the last year or so. I had an issue where my computer crashed, and my backup drive also got nuked.. so since then I now back everything up twice and still burn a dvd! I'm looking at expanding and getting the right lens for the right job... as well as getting rid of some LBA.
The 77 is for sure the one I'm leaning towards after a night of rolling around not sleeping. I'm at least 6 weeks out from buying and I'm already staying awake at night? I got a problem.
The Sigma 30/1.4 is not in a focal length I would use. I rarely find myself going below 50mm. And if I do it is usually with my Fisheye. My DA* 16-50 gets very little use month to month as I favor my DA Limited 40, M 50/1.7, and Tamron 90 Macro out of my kit. So I think upgrading my M 50 would be a better investment. Or the Limited FA 31.... I don't think I'd use it much, but the FA Limited thread is full of LBA!
Maybe these low light shots will be a bit better
