Bob,
It's the same but a bit better. The SR-7 has a bit of a detent in the down position. Many times I accidentally lock up the mirror on my 101 & 102.

Some Canon minutiae for you, Bob. There are three F-1 models. Canon F-1 and F-1n (small "n") are essentially the same camera and both have mirror lockup. Canon F-1N (big "N") is a different beast and does not have MLU.

Interesting discussion, but I wonder how many people having a camera that has MLU ever use it. I remember using it only very rarely, once or twice with long focus lenses, and a few times if I had to photograph machinery in a factory or workshop. In both cases the camera was held pretty securely and shake-proof on my Manfrotto tripod with a big Benbow ball and socket head, and I couldn't see any difference between shots using MLU and shots not using it.
Another feature that a doubt is used very much is delayed action. The only times I recall using it were again when photoraphing machinery where the main light came from roof skylinghts on one side and was very directional.
I used to meter the exposure for the available light, set up the camera with a weak small flash on top of it, put a tiny slave flash transmitter somewhere inconspicuous in the picture or where it could be cropped out, set the delayed action going and walk to one side holding my hammerhead Metz where it would brighten the shadows. It saved carrying a second tripod just to hold the Metz on a long extension cable.
I also used the same technique sometimes at a motor show or an industrial exhibition to avoid having cars or whatever I was photographing sitting on a big black cushion.

You can add Nikkormat FT3 to your list. Mine has MLU.

I read a theory somewhere that MLU is useful at shutter speeds between 1/30.1/15 and about 1/2 sec. I think the idea was that at faster shutter speeds the action is over before vibration has had a chance to effect the image and at slower speeds the vibration has settled out. I have no proof it is true nor can I find it again. Personally I use MLU on a tripod to try and ensure the sharpest image I can manage. It is a PIA and don't ask me when the last time was that I used a tripod. I suspect that you are correct that it is a little used feature today and likely one of the reasons it is not found on most SLRs today aside from cost savings in manufacture by omitting it.

Hi Peter I became interested in this feature as Sherri and I wished to experiment with night photography. As it requires very slow shutter speeds and of course a tripod. But at speeds like 1 sec. if I could eliminate the mirror slap...all the better, I figured. So, to answer your question anyone wishing to do night photgraphy at speeds like 1/2 sec or 1 sec.-----would like very much to have that feature. Bob

Bob:
I can appreciate your point, Bob. With most of the type of photography I mentioned I needed a small aperture to get depth of field (technical magazines put information way ahead of art in the pictures they use).
If I recall correctly, my exposures were in the order of 1 sec at f/11 plus a little help from the on-camera small flash. The Metz was used mainly to light up the shadow areas. In those days I was using black and white for this sort of work, invariably FP4, so I wasn't really worried about any conflict in colour temperature from different light sources such as flourescent and flash.
My massive Manfrotto tripod (too heavy for me to carry around outside now) is so rock-steady that the presence or absense of mirror slap on the Canon F1 or A1 didn't make any discernable difference in a 10x8 print.
Even so, with any camera you're wise to eliminate all the possible chances of camera shake you can. Good luck with the night pictures. I look forward to seeing some results.
