Here is a shot taken with a DSLR and I fail to see any problems produced by mirror slap:

You may not see it in this (very nice) shoot because mirror slap vibration is noticeable only at shutter speeds longer than 1/40. Probably because frequency of vibration is around 20 Hz.

And even a bit faster than that as pixel densities go up. The A77 already has a higher density than the D800 in the OP.

But isn't that just why MLU and later (to a degree) SLT was invented? So we had ways to deal with or completely do away with mirror slap problems?

I must admit that I don't quite see the meaning of this thread. The original Nikon post and thread just shows that MLU helps, so where is the beef? OK, it also shows that faster shutters are required, when the pixel density goes up. Of course SLT works, too (better, really, because there is no mirror).

Barry is probably laughing his head off somewhere...

Regular MLU is quite limited in its usefulness, in the sense that it doesn't go well with handholding the camera and you're always stuck with a delay of (usually) seconds. Great for planned shots from tripods and such.

Sure. MLU is a band-aid. But a very necessary band-aid when working with a mirror.

Mike
