I'm still baffled why hdr is the only mode on the camera that does not have some kind of pre-delay option or timer, or antishock mode. Focus stacking, bracketing, hi-res, etc... all have it.
I think Olympus needs to offer a shutter type option inside the hdr mode so you can pick what you want.
If enough people raise this issue, I'm sure they would. I feel like I've been the only one yapping about this since day one. Actually, I'm much less concerned about shutter shock in an hdr image because of the spread of exposure time...but I am concerned about vibration in general from triggering the camera via the shutter. I prefer not to touch my camera when I'm on a tripod. A self timer is nice, a cable release is slightly inconvenient. When I work, I have been triggering my hdr panoramics from my cell phone. Annoying, but it works.
