Re: First Sighting: A7rii Thin filter in action


Now let's compare A7 NKIR UT with Leica M20
Lens: Zeiss ZM 25mm 2.8
PP: adjust exposure, color picker at the same spot for WB, adjust tint of A7 slightly to match color, sharpening 31 with radius 0.8 (on the indoor wardrobe I used 51, 1 which may be a bit too much), no auto tone as done previously.

The images are at 100%. It was cloudy and pretty muddy weather and thus images apperar to be less contrast and less sharp than normal. It should be added that my 25mm infinity focus hard stop is accurate but for this test, I also cross-checked the focus with evf.

Sony A7 NKIR UT tops out Leica 240 in terms of sharpness in ALL AREAS even at f11. Contrast is also better on Sony. Vignette is about the same on both (Leica's lens detection was turnoff).

Sony A7 NKIR UT tops out Leica 240 in terms of sharpness in ALL AREAS even at f11 where Leica's images are affected more by diffraction. Contrast is also better on Sony. Vignette is about the same on both (Leica's lens detection was turnoff).
