That works! The shutter must be held down for the duration of the exposures, but I set it at 6fps, 3 exposures and I think I'll remember!
Yes, using the d4 delay removes the need for the self timer, so that works.
I pushed my luck to see if I could get a burst, with a delay, with the mirror up. no go ;), but I really wasn't looking for that anyway.
Thanks all, yes, great camera.
I shot the above with the Mup. Even at 1/250, the mirror slap affected sharpness. I was surprised how well the image held up under significant cropping in LR--another testament to the camera and the lens
