Never heard of it (although I am a Dutchman ) but it seems that it's a mirror lens with a reflex mirror built in. Sort of like the Leica Visoflex. Maybe it has a Leica 39mm mount too. Must be very rare... _________________ Peter - Moderator

Old Delft was a high quality Dutch lens-maker.
They had SLR lenses in many mounts, particularly Exakta and Alpa.
Also a range of industrial and large format lenses, etc.
It seems they made only small quantities though. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

I'm guessing the reflex mirror in there is because it's for use with Leica rangefinders and such a camera wouldn't be able to focus through the viewfinder with this monster mounted on it? _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

I suspect this lens was supplied with several camera mounts and therefore would not necessarily be able to fit on the Leica Visoflex and whatever contraption Zeiss had also. So they made the lens with its own reflex finder to avoid the problem. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

You got a real bargain. This is a very interesting collectors piece.
I have come to a different conclusion as to how this was designed to work. I think it is a combination spotting scope/camera lens, and not quite a combo-replacement for the Leica Visoflex. I think the cable just switches the view from telescope eyepiece to the camera.
As to whether this can be mounted on your Olympus - it all depends on the camera mount supplied, which the vendor does not say. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

Wow, about a tenth of it's value.
If it's M39, which it probably is, should be easy to adapt. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

I just found the size of it on the web ( funny old dutch add) and its not so big as i thought it would be. only 15cm (5.9 inch) long and 10 cm (3.9 inch) thick. so its actually tiny :p

i will keep u up to date ^^ |

I own an Old Delft DELCA TD50 f=50cm 1:6,3 in Exakta mount. Bit slower, but to my knowledge, even rarer. Never saw another one. A pity is, that I can't use it on my 5DII, because of the pretty thick bayonet flanges, protuding to far into the camera and blocking the mirror.

I believe the cord is for flipping the mirror to switch between telescope and camera mode. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

to be honest if it is stuck to use the lens/camera mode an i can use the lens for testing ill just leave it like that. but if it is stuck in scope mode i have no id what i would do.
Quote: i can fix it! nope made it worse

hi,
well i got my fototel today.
Its an m39 so it fits my Olympus , i can get infinity,
The outside of this lens is very nice not allot of scratches, glass has no scratches too.
the view mechanism is stuck in camera mode, so i can test it on my camera
focusing smooth.
but ( there is always a but :p) the big chamber (mirror and glass) is infested with fungus. don't know jet if i would clean it or let it be cleaned.
but if i would do it myself, the glass is not a problem, but the mirror, is it fragile ? ( like extremely fragile ?-).
there is not allot of sun
i will post test shots soon.

Nice lens Karel,
Pity about that fungus. When it would be on a glass surface it probably could be removed without too much harm. On a mirror is a different story of course. These surface mirrors a generally speaking quite vulnerable. The mirrors in my rangefinder cameras i allways clean very very gently. I normally use ROR (kind of optical lens cleaner) and first try that out on a corner to see how the surface deals with it.
A generous dose of UV-light (sun or special UV-lamp) would probably stop that fungus from spreading but then again you have to remove the fungus remnants. If i was you i would get in touch with amateur astronomers as these sometimes build themselves mirror telescopes and surely would know how to clean or resilver mirrors. _________________ -------------------------------------------------------

hi,
first thoughts are a bit divided, it has some good sharp areas an some soft spots.
I think its because of the fungus an the dirt inside.
( and i think its around f7 instead of an f5 because of it).
ill let u decide. ( there was medium light, oh and windy ).
(at some parts the hairs are very good visible (first three +1 sharpening on camera).

I recently got a copy of this lens. It had a problem with some residue on the glass on the inside surfaces. Luckily it was quite easy to clean, and it works quite well now:
