Still shot with Pentax LX. It seems to me that all 3 lenses under the test (Quinon, Summicron-R, Planar) perform well with color negative films. I really like Quinon’s rendering of red color. Zeiss seems to have more brilliant tone in the whole image (but I tend to miss the focus in the largest aperture), while Leica R50 always performs above average without any unexpected issue.

Film is still the expired Kodak Tri-X @ ISO 80. Shot with Pentax LX / Steinheil Quinon 55mm F1.9 + Zeiss Contax Planar 50mm F1.4

It seems R50 has better “3D pop”, at least for the B&W films.

Shot with Pentax LX and Voigtlander Septon 50mm F2. Film is still the expired Kodak Tri-X @ ISO 80.

Experimenting with two rolls of expired Kodak Tri-X 400 (shot at ISO 100). Pentax LX + Leica Summicron-R 50 F2, Pentax MZ-5n with FA 31mm F1.8.
