Leica SL: Hot Pixels + Pattern Noise at ISO 100

Get the Zeiss ZM 35mm f/1.4 Distagon in silver or black ($250 rebate at time of post). See also my Leica M wish list and Leica SL wish list.

In Guide to Leica I was preparing another aperture series for the Zeiss 35mm f/1.4 Distagon, when I was startled to see severe hot pixels (and some pattern noise) at base ISO 100 at only 4/10 second. Yikes!

      ƒ:  1.4,    2,  2.8,   4, 5.6,   8,  11
seconds: 1/30, 1/20, 1/10, 1/5, 0.4, 0.8, 1.3

Leica SL: Pattern Noise and Hot Pixels at ISO 100

Includes RawDigger analysis and images up to full 24MP resolution, along with two large crops for viewing convenience, at all apertures from f/1.4 to f/11.

I’m not talking about a few hot pixels at 4/10 second, but thousands that dominate the image in all dark areas. The reduced-size image below hides them, but they are prominent at full-res.
