Hello. I recently acquired a Carl Zeiss Jena Triotar 1:4/13,5cm T lens, however I am unable to identify the mount. Please forgive my subpar photograph - my 2 megapixel camera has no depth of field control. Any help would greatly be appreciated. |

I searched completed fleabay auctions for similiar items... I found this:
http://cgi.ebay.com/Carl-Zeiss-f-Leica-Screw-Mount-4-13-5cm-Triotar-couple_W0QQi temZ350058517397QQihZ022QQcategoryZ30063QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
The serial number on my lens is only 205 removed from the one on fleabay.
So I am guessing it is the above lens... |

So now that the mystery is solved... is this lens really 'rare' and worth upwards of a couple hundred dollars? For some reason, I find it hard to believe that the aforementioned seller was asking so much for this lens... |

This seller is always very pricey, but the items always seem to be in very good condition - both cosmetically and optically. Whether these properties, make the lens worth approx £600+VAT in the UK is another matter entirely! |

I would feel better using a Tessar or Sonnar and the price seems rediculous. I used a Triotar on an old rollie and found it very soft I have a colinar135 , it weighs a ton, all machined of brass. It may give a fair result but at what cost. I paid $30 American for it. |

The correct terminology for the lens in question is LTM, the thread pitch is imperial (inch). The L39 mount is a different beast altogether, both diameter and pitch being metric. In many cases you find that L39 lenses will screw into a Leica body; however, you do find examples where machining tolerances work against this and the fit will be very tight. Adapting a LTM lens to M42 is a pretty useless exercise - no infinity focus and in most cases poor 'macro' capability. A reversed standard lens and extension rings will give far better magnification and coverage |
