Advertisement Posted March 30, 2009 Posted March 30, 2009 Hi luigi bertolotti, Take a look here Guess which lens is this ?. I'm sure you'll find what you were looking for!
doubice Posted March 31, 2009 Share #2 Posted March 31, 2009 Hint: the mount IS a M mount... Alpa Kinoptic? Angenieux? Need more hints..... Jan Link to post Share on other sites More sharing options...
j_lir Posted March 31, 2009 Share #3 Posted March 31, 2009 it looks to have the same barrel markings as my .95 -- is it a canon? Link to post Share on other sites More sharing options...
farnz Posted March 31, 2009 Share #4 Posted March 31, 2009 Hmm, interesting - it appears to have a maximum aperture of f/1.4 and stops down to f/5.6 but the depth of field scale is only marked from f/4 and extends to f/16. Is this a modified cine lens, Luigi? Pete. Link to post Share on other sites More sharing options...
elgenper Posted March 31, 2009 Share #5 Posted March 31, 2009 A Kilfitt Makro Kilar? Seems it has a LTM plus an adapter ring. Edit: No, they weren´t f/1.4; stupid me... Howabout another Kilfitt? Link to post Share on other sites More sharing options...
jaapv Posted March 31, 2009 Share #6 Posted March 31, 2009 I seem to remember a Sonnar 50/1.5 of that shape, but this one is 1.4....But wait - there is an external aperture coupling. Nikon No- 45 degrees off...??? The alleged M-mount is clearly an LTM-M adapter It is very strange that the aperture ring stops at 5.6, but the DOF scale runs to 16. And that lens mount looks like it is home-made from an espresso holder, even half-hiding the aperture ring. It might be a Kinoptik conversion from Arriflex, but it would vignette in that case.

ljclark Posted March 31, 2009 Share #7 Posted March 31, 2009 Advertisement (gone after registration) Do the DOF marks have anything to do with the optics inside the lens body? If so, this would appear to be something in the 15mm to 18mm range, depending upon what circle of confusion the DOF markings are based on. (Or maybe not...)

That would be consistent with say a 20 mm 16 cine lens. Link to post Share on other sites More sharing options...
luigi bertolotti Posted March 31, 2009 Author Share #9 Posted March 31, 2009 He he he... really a 18 indeed... Welcome, dear visitor!

Distagon 18 for Contarex (a lens I consider a historical masterpiece) WITH a Contarex to M adapter (no RF coupled) which I even didn't know existed... before finding an Italian lab who makes it... in very small numbers... . Contarex lenses DO NOT have a f/stop ring... they used a absurdly complicated mechanism of coupling with a ring on the body front... so this adapter has a f/stop ring of its own... coupled with Contarex lenses' internal "actuator ring" which explains that strange little scale 1,4 to 5,6...to keep track of max aperture You can see my face reflected above the iris...

Albert4321 Posted April 1, 2009 Share #10 Posted April 1, 2009 I want to see pictures taken from this lens. Link to post Share on other sites More sharing options...
luigi bertolotti Posted April 1, 2009 Author Share #11 Posted April 1, 2009 I got the adapter 2 days ago, and made some test shots in house... maybe tonight I'll post some example: this is an exciting lens... I have also the Distagon 25 and am curios to test it too: of course, practically impossible to use longer focals due to focusing issue, even if I'll surely try some shot at infinity with the Olympia Sonnar 250... Pity I haven't another 18... a face to face test of this lens with new Distagon 18 and new Super Elmar 18 would be a lot funny : but I plan to take some trial shot 15 Heliar/18 Contarex/21 Elmarit asph at different distances - subject same size...

Mauribix Posted April 1, 2009 Share #12 Posted April 1, 2009 Luigi, my Super-Elmar 18 has just arrived yesterday... If you get the way to the mountains here, we could find a way to match the lenses... (BTW today I'm in Milan...) ciao, Maurizio Link to post Share on other sites More sharing options...
luigi bertolotti Posted April 1, 2009 Author Share #13 Posted April 1, 2009 It works, and works fine : a pair of full frame shots and a 100% crop from one, with M8 at 320 - tungsten setting - Distagon 18 for Contarex at f 5,6 Welcome, dear visitor!

luigi bertolotti Posted April 1, 2009 Author Share #14 Posted April 1, 2009 Quick but rather precise comparision : Heliar 15 - Distagon 18 for Contarex - Elmarit Asph 21 (no UVIR-lens recognition off) all three at 5,6 - 320 ASA. Different distances to achieve same FOV. The first series (no full frame) allows a good evaluation of barrel distortion (keyboard in foreground). Heliar 15 Welcome, dear visitor!

luigi bertolotti Posted April 1, 2009 Author Share #15 Posted April 1, 2009 This 2nd series (same order 15-18-21) of 100% crops from the previous ones gives an idea of respective sharpness. No sharpening at all in LR. 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 April 1, 2009 Author Share #16 Posted April 1, 2009 An observation on colors : looking at wall tapestry - piano's wood - Schubert's cover page, and having the originals behind me..., Distagon has the better balancing and fidelity (but, remember, all 3 unfiltered); indeed, at its times, Contarex lens set was a lot praised for its color rendition, but this result is so surprising that I think I'll make a more complete test in a simpler-cleaner lighting situation.

dkCambridgeshire Posted June 9, 2009 Share #17 Posted June 9, 2009 My Contarex to Leica M adaptor arrived today from Italy and it works fine using the 21mm Biogon on my M8.2 ie does not collide with the shutter. Only had it 2 hours so no worthwhile snaps to post yet. Cheers dunk Link to post Share on other sites More sharing options...
