    never heard of a 120mm, sounds like a bit of an oddity.

    Pentex made 42mm lens from 35mm to 150, for the most part, in 15mm increments, although from some reason they jumped to 105 rather than 100: 35, 50, 85, 105, 120 135, and 150. The 120 is somewhat rare, the 150 is easy to find. I find the 150 to be a better fit than the 180, I have a sologair 180 in 42mm as well, fast but just close to a 200. I dont think the 120 and 150 were carried over in the K lineup.

    just those 2, trond or the whole range of super-takumars?

    they must have had an enormous catalogue. then, i suppose all the manufacturers did. i read somewhere that minolta had made 53 different versions of the standard lens by the time they went to af....grin

    Good morning, Paul;

    The "15 mm increment" lilsting has some other anomalies in addition to the 105 mm. The 50 mm to 85 mm is another.

    There seems to be many curiousities in the way lenses were chosen.
    Enjoy;

    When they ask you; "How many Mega Pixels you got in your camera?"
    just tell them; "I use activated silver bromide crystals tor my image storage media."

    Anybody wants a Pentax Takumar lenses brochure? I got that hanging around somewhere in my bookshelf.

    In M42, you could go from 17mm fisheye to 1000mm Big-Macho-Tele, with everything in between. That's:

    17, 20, 24, 28, 35 (f/2 & f/3.5), 50, 55, 85, 105, 120, 135, 150, 200, 300, 400, 500, and 1000.

    Add to this the 50mm Macro, the 100mm Bellows (focuses from infinity to damn close on a bellows unit), some zooms, and two Ultra-Achromatic taks (85 and 300; focusing both infrared, visible, and UV light equally).
    Using film since before it was hip.

    i've played around with that 17mm. it's very strange...sort of semi fisheye, semi rectilinear....if that makes sense. not quite sure what it's meant to do

    Here is the greatest list of M42 lenses for all the m42 junkies:

    http://m42.artlimited.net/site_lenses.php

    I too have a couple of the "radioactive lenses" -- here is a good bit of information from Oak Ridge about that.

    i just knew sooner or later someoneone would come up with a list as long as your arm, thankyou very much....grin

    so these thoriated lenses are more oneoffs or oddities rather than a complete range or series?
