Is it possible to get tilt and roll angles from exif? I found only direction (yaw), that comes from GPS. But what about electronic levels?
that might be quite useful for panoramic photography. Specially if astrotracer is turned on and data is quite precise

I've noticed the same.
K1 + 24-70mm
vs 645z + 75mm

Same studio light, same model, same settings. Same C1 processing (but different profile). And i'm not happy with k1 picture.

You have a strange sharp pixel-size pattern on the leafs. 2 pixel of that pattern at 50% magnification become 1 pixel. What pixel of pattern shoold it show? that happens at 33% magnification?
Try to blur your image. The pattern should disappear.

Had an experience taking pictures at about -25 with 645z. Night, tripod, several hours multi-exposure.
Battery life was about an hour so i used 220V.
Absolutely no problems with the body ("frozen" LCD - isn't a problem). In terms of noise it's even much better.
But the lenses. It is just terrible. Frozen lenses (FA35, FA150-300) produce "triangular" stars. Probably because of temperature deformations of the lenses. So i'm going to buy some kind of heating specially for the lenses.
