20 Mar 2015: Sensor Thickness
My 50 Summilux did not meet its reserve, so I've decided once and for all (one hopes) to keep it. I decided to double down on the lens, and have sent my Sony A7R in to have its sensor glass replaced. A thinner glass cover on the sensor will improve off-center sharpness with that lens and other M mount lenses on the A7R.

The conversion will cost four hundred dollars, but will allow me to use legacy Leica and Zeiss lenses in monochrome with the A7R with much greater performance at wider focal lengths. Results have been posted on-line using 21mm and 50mm lenses by Lens Rentals and digiloyd that are encouraging.
This does mean I will be without the camera for several weeks. Thankfully, I have a new (old) wide angle lens for my Mamiya 6 and recently purchased a second film back for my Mamiya 645AFDII so I can switch between black and white and color film mid-roll. Having a camera in the shop will also give me time to print a little bit more. I have several photos I would like to enlarge.
I have mostly shot with Fuji Acros black and white reversal film and Fuji Provia color transparency film; so far getting better results with the 645 than the Mamiya 6; mostly because the 645 forces me to move more slowly. I also think I have not really understood the meter on the Mamiya 6 -- I am going to have to spend some time comparing its result against my hand-held meter. The photos I took in Gothenburg on average wound up a bit over-exposed. I need to go back and look at the negative to see if that was an artifact of how they were scanned or post-processed, or the exposures themselves.

So, lots of photography projects to keep me busy.
Only recently I have purchased some Kodak Tri-X 120 film. I'm curious to see what kind of results I get. When I first started photography in college, Kodak had just released its TMAX emulsions, so I never tried Tri-X. I have really enjoyed the digital pictures from the Leica M monochrom when I rented it, and my understanding is that its tonal response was modeled after Tri-X, so I am curious how things will go after I shoot a couple rolls.
