It's been a while ago I tested mirror shake and limits for handheld shooting with my setup (Contax+P45).
Inspired by this thread respectively the topic mirror/shutter shake I did this test again today.
Below screenshots from Capture One showing 100% crops; sharpening set to "Version 3.7 soft look" (after that I cropped them in Photoshop and safed the files as JPGs again… so there is double JPG compression; but the crops should be still good enough to tell the story).
First of all mirror shake of the Contax is apparently not so heavy, actually it's quite soft. But, of course, clearly visible.
Attachement #1 shows a shot from tripod with mirror lock at 1/60'' (f5.6); attachment #2 shows the same but without mirror lock (both with cable release).
Attachment #3 shows one out of 5 shots taken handhold at 1/60'' (and without mirror lock, of course).
That one looks "okay" but the other 4 samples look pretty much like attachment #4. So 1/60'' is certainly not the way to go here.
Attachment #5 shows a shot taken handhold at 1/125'' (f4). I made 9 shots and 4 out of these 9 shots look like this one.
The other 5 shots look pretty much like attachment #6. So roughly 50% keepers with regard to sharpness. Still not on the safe side…
IMO mirror shake is not a real issue at this shutter speed with the Contax… so maybe someone who can shoot handhold better than me - and I guess there will be many that can - 1/125 might be okay for handheld shooting with the Contax in conjunction with a ~ 6micron sensor).
I'd be interested how well the S2 & 70mm performs at 1/125'' (the 2 shots above at 1/125'' really look very good; question is how well you can reproduce this quality… I mean over the course of time, not in a boring test like mine) and if it is possible to shoot as well at 1/60'' without a significant loss of IQ.
