Which type 35mm Summicron do I have?

Discussion in 'Leica and Rangefinders' started by pensacolaphoto, Apr 29, 2010.

  1. My Summicron has no front ring. It is missing.<br />The lens is chrome, and it is made in Canada. There are no goggles.<br />Disrance scales: black for meter, and red for feet.<br />Where would I find the serial number if the front label is missing?<br />It seems to have an infinity lock.<br />f stops go from 2 to 16.<br /><br />Help?<br /><br />While we are on this topic, does anyone have a 'spare front ring" from a smashed Summicron?

  2. If it's chrome it might be the famous v1 8-element summicron. Is the infinity lock the wide thumb support?
     
  3. Hi Huub,
    It is a wide thumb support like stop.
    Once I get home I can post a pic of the lens.
     
  4. I now think that this is a V1 Cron.
     
  5. Only the v1 Summicron had an infinity lock.
    The serial number is on the (missing) front ring. Check with DAG for a replacement.
     
  6. Bill,
    DAG has no more replacement front rings.
     
  7. You can also check with Sherry at Golden Touch for the missing part.
     
  8. This is a good tip, Elijah. I will look for her email address.
     
  9. Can you show us some images of the lens?
     
  10. Will do. I will get the camera.
     
  11. Hi Raid
    Check your email for Golden Touch address.

  12. Thank you, Seth. Will do.
     
  13. I finally took some pics of the lens.

  22. I just need the front ring for the Cron. The glass looks to be very clean.

  24. It appears your lens is the first version M mount, (1958-1969). Some of the first version were manufactured in Canada, as this lens obviously was. Perhaps you can find a parts lens on eBay.
     
  25. It is impossible to tell from your photos but some screwmount versions of this lens were factory fitted and sold new with an M mount adapter which is held in place by a single screw. If you happen to have a lens like that, it is very rare.
     
  26. Hi Robert,
    I am no expert on the history of lenses, but I thought that the first lenses were made in Germany, followed by made in Canada.
    As in the case of other rare lenses, I will pretend that it is one of those ellusive screwmount lenses that were converted! The glass is very clean, but the lens has been well used, as you can see from the faded numbers on the aperture and distance ring.
    Thanks for this great tip!

  27. I do not see a single screw that attaches the M adapter to the lens. Would this screw be on the bottom of the M adapter or inside somewhere?
    There are 3 screws holding the barrel of the lens from the side.
     
  28. Eddy Smolov just told me that the lens is original Mmount with original parts. He also told me that the lens was in poor mechanical shape but the glass is good.
     
  29. If it were a screwmount version, you would have a 2'2" minimum distance (26") vs. your 28" indicated. Plus, the small set screw would be at the exactly 6 O'Clock position. (See Provided Picture)
    Besides Raid, you don't need no stinken ring...

  30. Thank you, Gus.I can see the difference now.
    I don't need "no stinken ring" for taking photos, but the lens looks strange without some "stinken rink"!
     
  31. Three screws means it is the regular M mount.
     
  32. If I ever come across a stinking ring, I'll let you know, Raid. However, you might think about using a flat black paint stick from Micro-Tools to blacken that bright chrome retaining ring. Micro-Tools in Europe.
     
  33. That's a good idea. Thanks.
     
  34. Hi Raid and Gus, I thought the screw Summis were also only 1m (3'4'') minimum focus!
    Great lens anyway, and much better close focus!
     
  35. Now I see it: With all due respect, Gus, don't you mistake a M3-gogles-type for a real LTM?
    Raid happily owns a regular M2-type Summicron, which focuses down to 0.7m, only the M3-type went down to 0.65m. Correct me if I stand wrong!

    Best wishes and good light!
     
  36. One more thing, Raid: If you really want to see the quality of this lens, take this ol' filthry off and put a shade on, many are comparted with the old 50mm Summicron. And like Robert said, matte blackening the chrome face will help, too! (could be a fine shaped thin black cardboard ring for not to damage the lens!)

    Best,
    Knut
     
  37. Hi Knut !
    No, it's definitely a "real" screw mount lens that fits & focuses on a LTM camera when the "googles are removed.
    Just keep in mind the caveat: The infinity is accurate either way, but as you get closer without the "googles", the error progressively becomes greater.
    i.e. A 10ft subject distance focuses at 8ft in the rangefinder, etc.

  38. Thanks for the comments. I am happy with the "non rare" M2 type Summicron, and I will blacken the chrome front, with the hope that one day I will find a front ring. I have many Leica lens hoods that fit this lens, and I always use a lens hood with my lenses.
     
  39. A 35mm Wetzlar version with goggles, serial No. 1,632,XXX, originally bought by a relative at a U.S. Army PX in Bavaria back in the 50s. One of my all-time favorite lenses!

    I have used these sticks and they are great for improving the look of old lenses or touching up the paint on cameras, even an M. I used mine to repair when some silver insulating tape pulled off some paint when I removed it. I still cover up sometimes but now use cut paper over any painted areas and then tape over that.
    They supply the touch up sticks in different colours too so you can get a yellow and a red for those lens which need that.
    The sticks are quite easy to apply and you just gently wipe off excess to leave the grooved numbers or script refilled and looking so much nicer.
     
  41. This the link to the black sticks that I refer to above, other available colours are white, yellow and red
