Orion-15 6/28 - any experience?

[Maxim]

Does anybody know something about this lens? http://allegro.pl/item306995532_orion_15_28_6_idealny_stan.html
Orion-15... wide-angle lens with M39 screw. Slow (F/6), but nice looking. I've never seen this lens before!

Thanks for the answer, Ballu! It may be a good (sharp) lens for landscapes, but probably it can't be used with dSLR. The rear element sticks out too far beyond the screw mount...

It is a Zeiss Topogon design, good without significant geometry errors, but strictly a range finder lens because of the register distance -- even without the protruding back element. There are some test shots on my FED-2 page, see http://galactinus.net/vilva/retro/fed-2.html

Veijo your Orion samples look great to me! Non-retrofocusing wide angles are unbeatable for architecture photography.

I wonder if one day someone will find an Oriogon lens

I have seen two of them during the last 3 months or so on ebay. Each of them went for about 90-120 Euros, so they are not that expensive, but not cheap either.
I was watching each copy, but decided that I did not really need it.

But one day, who knows?

Well I have an Orion-15 on the way and I hope to fit it on a Samsung NX10 via a LTM M39 adapter. Obviously it will be a bit touch and go with the rear protrusion. Interpolating the screen images is hardly precise measurement but I know that I have just 9.2mm maximum to play with (from the adapter manufacturer - it also is the full physical depth of the adapter which literally just squeaks in) but I don't know whether this is from flange before screw mount (I think it is) or from end of screw mount. In any case my rough calculation is a 10mm back protrusion from flange including screw thread on the orion-15. Hoping that the kick in to the back lens mount will allow it further inside the camera without fouling anything. After 9.2mm the intrusion has to pass through a rectangular opening 23.6x27.3 then there is a reasonable distance before there is anything to foul up (no mirrors to move - only a shutter). Therefore as long as the rear element is something less than a safety margin under 23.6mm and is not a moving element.

Wish me luck - I will report back - will be a while before I get it.

The Orion interests me as a no-distortion wide angle lens - slow I will have to live with. Provided I can get it to fit of course.javascript:emoticon('')

Welcome Tom! I look forward your NX experience, here we have minimal information from NX.
