Absolutely, and if I weren't shooting M42 bodies like crazy I would be lauding the K-mount version to high heaven. I think it's great that these things are starting to be offered in K-mount almost as a routine - I think getting it as an option on the Daguerre lens was a HUGE win for Pentax, and possibly one that opened the floodgates. Credit goes as much or more to the people who pushed for it to be a potential option as those (including me) who ponied up the necessary money (in lens-copy terms) that they actually made it for us.
I only hope there are enough of us out there who want these lenses and can justify buying them that it keeps on being offered. Me? I have so many 50 and 55 millimetre lenses already (including a well known clickless Soviet Tessar clone that resembles this a lot) that I simply can't justify another fifty-ish right now.
