Hi all - I just got my hands on an S1R to play around with. Most of my shooting is in manual mode and it appears that in order for one to see what's going on with exposure as aperture/shutter speed/ISO values are changing, you need to turn on the 'Constant Preview' feature. Problem is that everything in both the EVF and monitor is updating in slow-motion, which makes it unusable. Anyone else experiencing this? Am I missing something?
