    I take a lot of Bird/wildlife photos I am usually fairly close to the subjects and the sound of my shutter/mirror tends to scare them off .. Is there a way to lock my mirror up to make it quieter.. The camera I use are the K10D and the *istDL

    I'm sure your camera's manual will be able to tell you exactly how to do what you want. It will probably be under custom functions.

    But when the mirror's locked up you can't see anything.

    Agreed - mirror lockup is a feature on many DSLRs, but when the mirror is up you can no longer view through the viewfinder (the mirror is what reflects the light up into the viewfinder instead of allowing it to hit the sensor). I also belive that AF will not function either in this mode, though to be honest I have never tried it. The mode works best with tripod work where you are try to remove any shake at the time of shooting, but have time to setup and take a shot rather than being pressured for time or shooting fast moving subjects

    I belive some of the cameras with liveview allow for a silent shooting mode where the mirror is locked up but you can still view (though liveview) what the lens is seeing and also use auto focus.

    I think it's the re-cocking the shutter that makes the most noise.

    Doesn't the latest 5D have an option to not recock the shutter for just that reason

    Ages and ages ago (the 90s I think) Canon released a camera which had a fixed mirror. I think it was along the lines of a two way mirror - one side was transparent so you could see straight through the mirror. Don't know why they never made another one because it seems like a good idea.

    Spaceman, the camera you are referring to was a Canon RT (real time) this featured a pellicle mirror which was fixed and did not flip up when the image was taken. It was (still is) a great camera for these situations and also for capturing that 'decisive moment' as you could tell if someone blinked etc at a wedding and re-take, and in the film days this was a distinct advantage. the main disadvantage was viewfinder brightness sufferedby 1 or 2 stops. I am not sure why it was not developed more because it also gave you a much faster frame rate (no mirror flipping up and down) and also very much quieter with less moving parts. I still use my RT on a regular basis alongside Digital and other film bodies, when you use it you realise just what a good concept it is.


    Thank you to all, some interesting info there.
    I shall refer to the manual again as suggested and if possible I shall prefocus on a spot set up specifically "set up" for the creature to land/feed in, and release the shutter remotely by wireless..
    Thank you once again

    For the K10D, you only have the facility of a 2second timer that is programmed from the menu button/ select Drive mode etc. It si there to reduce camera shake for static subjects, and does so by locking mirror up 2 seconds before shutter release. During which time, viewfinder is blacked out - and of sourse you still get the mirror noise. K20D has a version of livewiew that locks mirror up (but then you would have to manually focus using the liveview screen). I don't have the K20D, but from having tried one, I also think the actual shutter is quieter than my K10D.

    My Pentax *ist film job has mirror lock up with 2 second delay so you would think it would be on the 20 D,but that's designers for you.
