    Speaking of Pentax lenses...

    I just got a nice Pentax 55mm 1.8 Asahi Takumar M42 from a guy, who had it laying around since his venture to digital. The lens appears sharp and crisp, all functions are fine. I will be testing it on my Spotmatic. Any opinions on this lens? I am not at all familiar w/ it. Sure seems nice! Has a very long focus range.
    Any info or insight much appreciated,

    Check out the above link. There are a lot of reviews and some information on this lens and its variants.

    I have a 55mm f/1.8 M42 Super-Takumar which I love.

    I have the same lens, bought it in 1967, very sharp, great color, I still use for both film and digital, K5 and Sigma SD 9 and 15. Of all the normal lens I have the only lens that I tested to be sharper is the Konica 55 1.4, it tested out as sharper than my Pentax K 50 2.0.

    The 55mm was made for years with tweaks, the final version being the SMC Pentax one with a K mount which was sold with the K series bodies (KM/KX/K2).

    The f1.8 and f2 versions are optically identical - Pentax merely added a baffle to reduce the maximum aperture on the f2. They're now pretty sought-after as portrait lenses for digital use and obviously by those who collect and use vintage film gear. The K 55mm f2 was only sold with the K1000 and then only for a year or so, the f1.8 version lasted 1975-77 with the rest of the K lenses.

    Pentax abandoned the 55mm focal length when the M series came out in the late '70s, the lens was replaced by the M 50mm f1.7. The 50mm f2 was a slightly later addition intended to provide a cheaper kit lens, and while it's no embarrassment the f1.7 version is better.

    The link to the Pentax lens database above covers the M42 versions, they also have pages for the f2 and f2.2 versions. If you look under "K series primes" you'll find the K versions.

    Thanks for all the info everyone. I plan on putting that lens to good use. I was surprised that it has a little radiation content. But so does another lens I have. I guess when they are that good they are hot!

    I don't think the f/1.8 lenses used thorium oxide, only the f/1.4 (and a few others).

    It's a wonderful lens. With all my Pentax lenses it's never the lenses that disappoint - only my abilities.

    Those screw thread Super-Takumar lenseswere some of the best lenses I've ever used. They easily outclass some current AF lenses in my opinion. The 35mm 3.5 and 105mm 2.8 were superb performers, and beautifully made...no cheap plastics then!

    In those days, 60 and mid 70s Pentax, Nikon, konica Canon and the other folks did not make consumer grade lens, the only differnace was speed. Build quaility of a Pentax Tak 135 3.5 was good as the the 2.0. I think the late 70s and 80 saw the concept of a consumer grade lens, Nikon E and Konica Hexar comes to mind.
