Question about a Sun 135mm LTM

Discussion in 'Leica and Rangefinders' started by leo c, Apr 15, 2004.

  1. I got a silver Sun 135mm F3.5 Telephoto with the serial #536**, in
    good shape with a little dust in the lens. I tried the lens and
    liked the results. My question has anyone any knowledge about the
    Sun lens and the quality of it in the LTM format? It is a LTM mount
    not T-mount and made in Japan.

    Before I give it a serious test and maybe have it cleaned I would
    like to know what kind of quality I might expect. It was a good buy
    and I'm not sure if I got a good deal or paid what it was worth. I
    really got it as a inexpensive way to test a 135mm on a rangefinder
    camera. I can see I might use it some maybe 5% of my shooting time.


    How would this 135mm Sun compare to a Russian Jupiter 135mm or a low
    end Leica 135? Are we talking quality lens or junk.

    Thanks

    If it were less than excellent, would that worry you?

    Neither underpriced like the former nor overpriced like the latter.
    It has a good reputation. The dust is highly unlikely to have any effect. If you have the lens cleaned by somebody who's not conscientious, chances are high that he'll reassemble the lens carelessly and it will end up worse than it is now. If the cleaning is conscientious, it's going to cost you. All this for a lens that you'll use for 5% of your shooting time? The cleaning doesn't make sense to me.
    Screw the lens into the camera, and go out and have fun with it. Incidentally, I get good results from another Japanese lens of the same vintage and price level, a Tele-Tanar 135/3.5 -- when I can be bothered to lug it around, which is very seldom. My Canon 100/4 is a much more portable and usable alternative, through no optical fault of the Tele-Tanar. (The Canon cost me less, too.)
     
  3. It's a lens formula that's hard to mess up. It should be just dandy.
     
  4. Sorry, the (Japanese-language) book that I thought had a favorable write-up instead says nothing. (The non-mention means nothing: only a minority of lenses are covered.) However, it has a glowing write-up for the same company's LTM Sun-Sola 90/4.
    Sun was a lens maker that survived into the 70s or perhaps even 80s by making SLR lenses (cf Komura).
