• When using a tripod, set [Image Stabilizer] to [OFF].
• When using a lens with an image stabilization function, turn off the image 
stabilizer
function of either the lens or the camera.
• You may notice an operating sound or vibration when the image stabilizer is 
activated.

I've left it at the default of 1-2 seconds, enough to confirm the shot, 
although not in detail, without getting in the 
way of the next one.

Almost perfect design. None of my QR plates would completely clear the rear 
screen edge. One came close, but still 
slightly got in the way of tilting up and down. I've bought another one that 
completely clears the screen and battery 
compartment.

The one design flaw for me is that the QR plate so far to the left makes 
putting on a hand grip problematic. It's bound 
to slip in front or behind the body. The RRS bottom plate, although otherwise 
overkill to my mind, would be helpful if 
it had a strap lug on the right end, but doesn't appear to.

Manual says:
"• You may notice an operating sound or vibration when the image stabilizer is 
activated."

Somewhere on the web, I read that it is the IS mechanism. Apparently, it has to 
be in motion in some way or other in 
order to react quickly enough when called on.

Nice to be warned about. I haven't run into that.

No, that's because they use a thin margin around the actual image area for 
sensors that are covered, to set base points.

I think AG was talking about letting midtones and shadows go unnaturally low, 
in order to avoid clipping highlights, 
then bringing them up again in post. And indeed, the E-M5 is awfully good in 
this area.

The rubber right thumb rest is a HUGE advantage. Right where so many cameras 
put something small and at least slightly 
slippery - and a couple of buttons, Oly has but a big, rubber rest. Wonderful 
for my hands.

Seems pretty fast to me. I was just this afternoon shooting some bees, half 
pressed, waiting for them to come out of the 
depths of flowers. Low hit rate, but I think more my reaction time a d fast 
bees than shutter lag.

Yes, I like that.

I have both NR and Sharpening set down one notch. It seems to me that 
detail/sharpness is close to the ORFs. It's 
certainly easier to maximize in post from Raw, but the Large/Fine JPEGs are 
good.

I dunno, feels good to me. I certainly wouldn't want it to be any larger or 
heavier just to impress with apparent build 
quality.

I've been picking up bits and pieces to complete my kit. The combo 
wired/wireless release just came. Haven't even tried 
it yet. spare batteries look good and charge. Won't know how well they last for 
a while yet.
