earleygallery Posted November 25, 2013 Share #21 Posted November 25, 2013 Advertisement (gone after registration) It's a puzzle for sure! I'd like to see a view directly from the top, to see how the lens looks under the 'flange'. I guess running a roll of film through it and taking photos with the lens in various positions might solve the question too, but I'd agree with it being either a shift lens or some sort of stereo device, although it does seem a little too limited for that.

Silverwood Posted November 29, 2013 Author Share #22 Posted November 29, 2013 Thank you everyone for your interest. I will post some more pictures in the next couple of days as requested. The lens doesn't have a screw or bayonet mount, it merely pushes onto the camera body, so can be shifted in either a horizontal or vertical plane.

Silverwood Posted December 1, 2013 Author Share #23 Posted December 1, 2013 Here are pictures of the lens in profile, and the camera without the lens. The lens just pushes onto the body, no screw or bayonet fixture. The little button that some referred to is the focus finder. It is still possible to focus the camera even with the shift movement. I don't think it was ever anything to do with a microscope. My father worked as a photographer in Blackpool (taking holiday snaps - face through the board etc..) between 1945 - 1950, don't think he would have had any use for a microscope lens. I think the serial number is 464001 - so 1938. Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!

luigi bertolotti Posted December 2, 2013 Share #24 Posted December 2, 2013 Sorry, HOW is the lens fitted to the body ? NOTHING that secures it ? Is a simple push-on as you write ? Link to post Share on other sites More sharing options...
christoph_d Posted December 2, 2013 Share #25 Posted December 2, 2013 Gentlemen, I was wondering if the area which is sharp and properly illuminated by a standard Elmar would be sufficient to provide enough room for architectural pictures if the shift option is used? Wouldn't most likely vignetting and / or unsharp corners occur? Kind regards and thanks for posting the images of this curious object, C. Link to post Share on other sites More sharing options...
jc_braconi Posted December 2, 2013 Share #26 Posted December 2, 2013 Sorry, HOW is the lens fitted to the body ? NOTHING that secures it ? Is a simple push-on as you write ? Looks logical : after focusing using the engraved scale, you can place the lens body and adjust the sliding way the way you want to use. Link to post Share on other sites More sharing options...

We are all curious, you have to try the "gimmick" in order to judge the results, please try it and post photos taken with this lens. Best wishes...

pgk Posted December 3, 2013 Share #30 Posted December 3, 2013 Will the lens rotate within its 'push in mount' so that the lens can be adjusted without having to undo the small screws which position it relative to the camera? I ask because I can see it being used for stereo photography - although I'm slightly surprised that there are no alignment marks to ensure that the lens stays parallel to its original position when it is moved (does that make sense?) given the amount of effort to build such a one-off - there may well be easier engineering solutions. I doubt that its for architectural work because I suspect that the lens has insufficient coverage to make this viable and in any case viewfinding would be purely estimated. A curious adaption for sure. Link to post Share on other sites More sharing options...
jc_braconi Posted December 3, 2013 Share #31 Posted December 3, 2013 For making architectural pictures it is relatively easy for hand use but for strereo ones you need a sturdy tripod for getting every thing in level and alignement for be able to use a sliding lens... It is more easy to make / use a slide bar like the FIATE or FIARO Link to post Share on other sites More sharing options...
pgk Posted December 3, 2013 Share #32 Posted December 3, 2013 For making architectural pictures it is relatively easy for hand use ..... Yes, but a 50mm lens which isn't all that useful often architecturally AND I doubt that the Elmar's circle of coverage near infinity focus will allow for any significant movement and certainly not as much as it appears that this lens mount allows for. Its a puzzle. Link to post Share on other sites More sharing options...
