WARREN CONNECTICUT – I experimented today with a “new” camera. I sent my several-years-old Sony a7rii to Monochrom Imaging for conversion to black and white only. This service removes the camera’s bayer filter layer; this coupled with converting the resulting files with software the does not run a de-mosaicing routine should approximately double the resolution of the sensor from the camera’s native 42 megs to a whooping 84 megs, way into medium format territory.
Key questions are whether the camera works properly after the change, whether the theoretical resolution increase is actually achieved, the impact on shadow detail and dynamic range, whether the best native Sony and Zeiss lenses are up to the increased resolution, and whether the sensor’s rendering of gray scale is attractive. I’ve can report positive impressions on all five questions – I’ll be shooting with this camera a lot over the coming months.
The barn below is a test image – I use the barn frequently to test resolution and other aspects of an image. As you can see the rendering is lovely. What can’t be conveyed on the web is the insane amount of detail captured. The other two images are from the same camera captured during a session on show shoes. Winter continues here.
Day 3069 of one photograph every day for the rest of my life.
WARREN CONNECTICUT – Another distracted day. This is the busiest that I’ve ever been in my day job. I took my Sony Alpha 7r ii out to the barn, which for us has turned into a giant storage bin. Then dogs at a party later in the day.

WARREN CONNECTICUT – I’m continuing to shoot with my antique Carl Zeiss 50mm lens, which stopped down is excellent for landscape and wide open has a lovely signature for portraits or just about anything else. Paraphrasing myself from a few years back my research indicates that the optical cell (the optical workings of the lens) was produced at the Carl Zeiss works in Jena, Germany in December 1945. So it actually is a Zeiss Jena 5cm f1.5 Sonnar. The lens cell was subsequently fitted to a Leica screw mount body by an unknown third party, probably in Germany, the UK or US, for sale in the UK or US. The distance scale is denominated in feet and Zeiss itself didn’t make any lenses in Leica mounts as Leica was a competitor (Zeiss and Leica were the equivalent of Nikon and Canon today). I can see why it would have been worth the trouble to convert this lens to a Leica mount: it is actually the equivalent of an modern lens in most respects at f4 and beyond – its performance is simply breathtaking and as noted above it has a lovely signature.

WARREN CONNECTICUT – Martin Luther King Day. A Holiday so we’re still in Connecticut. The light was bleak but not interesting so not a lot of landscape imagery. I took this in the barn with my new Leica S.
