    Thank you, just moved over to a F100 and enjoyed the damped sound of shutter/mirror
    Was thinking of buying a F5 'cause it's MLU, but reading this doesn't encourage me anymore to do so

    Anyone who can add to the list 35mm SLR's with MLU?

    While not exactly MLU, the various Nikon FM/FE series cameras (and possibly others) raise the mirror and close the diaphragm when the self-timer is started.

    This is effectively MLU, at least for subjects where catching the decisive moment isn't important...

    MLU cameras:Pentax KX,LX(?) Nikon F/F2, Nikkormat FTN/FT2, Canon FTb/F1, Minolta SRT101.
    Probably more but these are four commonly available cameras. I don't remember if the OM1 had MLU or not, but don't believe it did.

    The OM-1 was the only Olympus OM model with mirror lock up, which combined with its size and weight made it sought after among astrophotographers.

    Leica R6/R6.2 have mirror lock up. If you flick the top of the shutter release on a Leica SL with a finger tip, it will lock up the mirror without firing. Not sure if this works on the SL2. I can make it work consistently on an SL.

    This works on many Pentax SLRs as well. I use it Spotmatics and various M-series. Don't think I ever tried it on my K1000, which I wish I had never sold... sigh.

    Thank you for the list.
    The thread started in the RF forum which I forgot.
    I will reignite it on the proper place

    Performing the laser pointer test seems like it would not be anything more than a curiosity unless the laser spot was actually photographed.

    And, as has already been pointed out, it's stupid to photograph the laser point, and one might as well photograph a resolution chart. If the laser is attached to the camera solidly, it's going to move in exactly the same way the camera is, and so it will be no surprise that the laser point stays a nice sharp dot, even as the rest of the photograph becomes blurred by mirror slap. Trying to acertain mirror slap by photographing a laser point from a laser attached to the camera is about as perfectly flawed a test as one could imagine. Lasers don't actually draw streaks on walls....they just look like they do.

    Isn't the point to see if the dot is blurred during the exposure?
    But, as yet I haven't photographed a dot. Laser or otherwise.

    I'm saying, that if the laser is attached to the camera, the dot is never going to be blurred, regardless of how shaky the camera is. If the camera moves, the dot will also move. Think about it. You need to photograph something that's external to the camera if you want to see if the camera is shaking.
