Picked up this Leitz Xenon 5cm F1.5 off Ebay, reasonable price of $400. This is after disassembly and cleaning. This lens is much better than what was expected based on reputation, I wonder how many examples suffer from haze and scratched glass. This one is quite clean now.

 

Wide-open on the M Monochrom, Orange filter. This lens uses a Tiffen #611 adapter for series VI accessories. I had two, the other on my Summarit.

and wide-open on the M9, ISO2500

And at F4 on the M9,

My "speculation" about the use of the Hexagon shaped aperture, less focus shift due to spherical aberration than using a round-shaped aperture. Same reason Zeiss uses the odd-shaped aperture for the post-war 50/1.5 Sonnar and modern C-Sonnar. This lens was spot-on used close-up and wide-open on my cameras, the Summarit- I believe was optimized for F2.8 at minimum focus. I modified one of my Summarits for wide-open and close-up work.

For reference- this wide-open shot is as received, before cleaning haze out of the lens, with a deep yellow filter and same vented hood as the other shots.

I think a lot of older lenses get bad reputations as they are not properly cleaned and adjusted.

Nikkor-PC 10.5cm F2.5, Leica Mount, Y52 deep yellow filter.

 

Wide-open.

14907832266_40cf976fe7_b.jpgNikkor 105/2.5,Y52 filter

 

This lens was designed in 1952, Sonnar formula, 1-3-1 configuration. The same lens was made in Leica Mount, Contax RF mount, Nikon S-Mount, and Nikon F-Mount. The latter was slightly modified to reduce the back-focus by 1mm.

Uncoated Carl Zeiss Jena 8.5cm F2 Sonnar, Contax RF Mount.

 

Wide-open on the M9,

Adapted to the Leica using a Contax to M-Mount adapter with an "Indexed Cam". I used thin layers of copper tape to correct focus for close-up to infinity. Lots of trial and error, it works.

I ended up making a custom hood for this lens, really helped with the uncoated optics.

Late-run Nikkor-HC 5cm F2, Leica mount. This is one with the Black aperture ring. different construction from the early lenses, different coating. I'm not sure if the optics actually changed or not. After taking one apart- it's a Sonnar formula lens, but the individual elements are different from the Zeiss lens.

 

With red filter, at F2-

At F2,

This is a great lens, smoother Bokeh than the 5cm F1.4 Nikkor. It is heavily made, and can be modified to RF couple to 0.7m. The "much less common" Tanar 5cm F2 has a very similar look. Need to take it out.

A member of another forum inquired about monochrome conversions on the M8 and M9. Took both cameras out with matching lenses. I've done the same comparison between the M8 and M Monochrom.

 

These J-3's are very, very good- as sharp as my 1943 5cm F1.5 Sonnar "T". One of the J-3's has a Serial Number stamped internally showing it was made by Zeiss in April 1945.

 

I hope people are not tired of these images... Somehow I've built up a collection of 70 or so lenses in Leica mount. 4 of them are newer lenses that would not fit in this thread, "new" meaning under 15 years old. Many of them are custom conversions to Leica mount. I like this thread because it shows Jeffo has this disease worse than me...

The 1950 KMZ J-3 looked like it was "Assembly Practice" in Russia, the focal length was incorrect and the machining for the mount was so bad it was held together with sewing string. The focus of the original lens was way off at all distances, explaining why the glass was in perfect condition. Required changing the spacing between groups and transplanting into an LTM mount.

 

KMZ J-3, at F4 on the M Monochrom. Red filter.

And wide-open at F1.5, no filter.

The focus mount is modified to maintain focus to 0.75m

This lens is unusual. It is a 5cm F1.5 Sonnar formula lens, made from the left over parts of six different incomplete lenses used to repair others. Four of those were Jupiter-3's, Two were Carl Zeiss Jena Sonnars. Rear fixture and triplet are from a KMZ J3, barrel from a Sonnar, middle triplet from a Sonnar, front element from a ZOMZ. Focus mount made from parts of 3 broken J-3's. The KMZ rear fixture and triplet is compatible with the pre-war and wartime Zeiss 5cm f1.5 Sonnar, the front element and middle triplet can be interchanged between any of the J-3's and the Sonnar.

 

Wide-open on the M8,

A quick test of a lens just picked up, a Minolta Chiyoko 11cm F5.6. This lens is smaller than the 9cm F4 Elmar, uses the same sized filter. This lens is early 1950s, is hard coated. Higher contrast than the Elmar, close-focus is 6ft. first impression- Japanese rendition of the Mountain Elmar.

Squirrels love to run across this downed tree.

 

15296140144_f0a8a4ffdb_b.jpgMinolta 11cm F5.6

 

Higher contrast than my uncoated 9cm f4 Elmar, I will try this one out on the M Monochrom.

Swirly Bokeh,

 

15892588096_be0ac00209_b.jpgMinolta 11cm F5.6

 

Minolta stuck with the Japanese 32x24 format for a long time, probably explains why they were not popular outside of Japan. Has anyone else noticed that the u43 standard follows the 32x24 ratio?
