    From this weekend: ISO1250 equivalent, using ISO160 and -3EV exposure compensation, “Auto-Levels” and some curve adjustment in Photoshop.

    These are with a 1952 Minolta Chiyoko 5cm F2 lens, wide-open.

    All hand-held,

    Version 1.2 of the software is out, easy to use, and something that should be considered especially of you use the M8 for Monochrome conversions.

    Nikkor-SC 5cm f1.4, at F4.

    Simulated Orange filter using LR4.4 presets. No exposure adjustments made in Post- this is “1-Click”.

    Color original, lots of room to stretch contrast, pull of details- if you need to.

    I've uploaded my initial batch of images taken using the V1.05 raw convertor.

    all I can say is- Leica should have had 16-bit DNG in the original M8 firmware, and Thankyou to Arvin for doing this.

    I was surprised to learn that the Nikkor 5cm F1.5 AND the Simlar 5cm F1.5 were both designed in 1937. I also have the 5cm F1.5 Simlar, one of the first made- #74, came with a 4-digit Leotax D-IV putting it in the 1949~1950 range for manufacture. It is a Double-Gauss design, 7 elements in 4 groups, an original design. The other F1.5 lenses went to 7 elements in 6 groups. Another article.

    Hopefully the viewing permissions have been corrected on the site I used.

    http://www.leicaplace.com/f2/nikkor-sc-5cm-f1-5-lens-brought-attention-japanese-camera-industry-185/

    I wrote an article on the lens, learned some things about it. Everyone should be able to see the images posted in the article, if not- please let me know.

    Next article will be a comparison of two Jupiter-3's with a modern C-Sonnar. Took all three out to Manassas battlefield for Memorial Day.

    I've heard of those…. Jason Howe hosts my DIY guides for shimming the J-3 for a Leica. Many are adjusted already, some require adjustment for a Leica.

    One with my 1950 KMZ J-3, wide-open. There is a history to this lens: the serial number stamped internally show it was made in April 1945. It was “misassembled” in Russia, the optics were the incorrect distance, and it could not be used. On the bright side, the glass is perfect… it had never been used.

    These are with the 1943 Carl Zeiss Jena 5cm F1.5 Sonnar “T”. I repaired this lens, including moving middle triplet back into place. It had been knocked out of position.

    It must be a permissions on the site- I've inquired about it with the admin!

    The “Beauty shot” of the two lenses, and the Nikkor-SC 5cm F1.5 wide-open.

    The “old trick” is to use black paint to fill in the scratch. This prevents the scratch from producing a reflection and flare, which is the primary source of image corruption. After filling it in, I doubt you will see any difference in performance.

    Beautiful picture, the contrast of the sky and clouds make it a stand-out.

    What filter -if any- did you use? I've been using orange and red to get that type of sky.

    Very nicely done, must be like riding a bicycle…

    No one ever questioned using black and white film, I could never understand why photographers were so skeptical of a Monochrome digital camera.

    The thinking is like that of using Black and White film, more thought going into the image before it is made, less time spent on the computer “fixing it in post”. I like mine.

    Time to find editions of the “Leica Manual” by Morgan and Lester. Some good chapters on the use of color filters. Last night it was “35mm Technique” by Newcombe, 1948. A great chapter on using color filters and sensitivity of the human eye to color. after reading that chapter, use of a Yellow filter makes a lot of sense.

    The clean images: sensor uniformity, resolution, and dynamic range- just amaze me. ISO 2500 performance is incredibly smooth. I've used Kodak detectors for 20 years, starting with the KAF-1600. This one is the best ever. I am biased towards CCD's. It will be interesting to see images from the new M, but I am satisfied with the current setup. M9 for color, M Monochrom for B&W.

    I've been on a kick lately to convert 50mm SLR lenses to RF coupled M-mount. 50/1.7 AR-Hexanon, 50/1.4 Pentax Super-Takumar, and a Canon FL mount 50/1.4.

    The Canon 50/1.4 FL mount on the M Monochrom. The CA on this lens is very low.

    Wide-open, FL-B filter to put a dip in Green to increase contrast.

    The SLR lenses maintain RF coupling to ~0.65m.

    Canon 50/1.4, now RF Coupled by

    Coupling made from cutting up the leg of an old broken tripod, and retaining ring from a Parts Jupiter-3. “Shimmed” using mylar tape between the shim and tube. Fotodiox M adapter, $30. Total cost, about $50.
