Petri 7s by

Recently bought a Petri 7S rangefinder, ran a roll of Cinestill 50D through it, very pleased with the results. It took me a while to find an example that was owned by a photographer instead of some random seller trolling through estate sales. The Cinestill has a really nice character, though both the 50D and 800T blow out highlights a bit because the film lacks an anti-halation backing as modified for still use. This isn't really a weakness for me, as it gives the film more character, but you do need to allow for it. I recently saw some shots of ocean surf with Cinestill 800T and the spray had "bloom" on it from this effect and it was stunning.
