Originally posted by DeadJohn Does ES cause extra noise or reduced dynamic range?
No, from what I've seen, done some comparisons of noise ranging from no LV, with increasing LV time, there isn't any visible additional noise due to sensor heating in LV mode, I believe sensor temperature in the K1 to be well controlled.

No. This was reported but apparently not seriously considered by Ricoh. Either they are planning to add this as a selling feature for the next model, or they don't care.
Originally posted by Paul the Sunman Unfortunately, the ES also turns off shake reduction, so it's not for full time use.
... yes, that can be annoying. From experiments, part of the blur observed with DFA28-105 is due to small camera motion also induced by mirror and shutter (kinetic energy from moving parts has to go somewhere...) because the DFA28-105 is very light weight, SR is not as good as ES to avoid blur, but I found SR to reduce the effect of mirror and shutter induced motion. Now having SR permanently switched on helps, I certain don't get the sharpest images with shutter speeds from 1/30th to 1/200th but with SR On the blur is still well controlled.
