Yep, me again. This time I am asking for input on the mirror lock up function. It seems to be an ideal solution to prevent camera shake on a telephoto whilst taking plane pics. But is it too good to be true and can you in fact use it for this kind of photography?
Any information would be welcome
CD :confused:

Thanks gents, as usual the information is most informative.

It’s intended for longer exposures where the mirror slap would set up a vibration. Locking the mirror up allows you to wait until the camera is still again and then fire the shutter. Since it requires a double shutter button depression I wouldn’t have thought it would be much use in any other application.
Correct. It would be useless for A/c photography (Unless you are doing tripod shots of engine details or similar). With mirror locked up, you can’t see through the lens, so panning would be a comical experience.
I use it for landscapes and macro, where (On a tripod) I set up the shot in normal mode, lock the mirror up, press shutter again when the time is correct (I may wait for a cloud to move or something).
Also, (For Still life or tripod work) if you haven’t got one, invest in a shutter release cable. Unfortunately, they are circa £25 (It’s only a goddam cable with a jack plug on one end and a two way switch on tuther end).
Or, use the self timer mode. With detail macro work or a long telephoto that isn’t supported, if you are even gently touching the camera to press the shutter, your pulse will shake the camera…or you will twitch.
Tripods that are strong enough to hold up the Albert Hall still have (Approx) 50mm square plate to connect to the camera. But obviously, a beefy tripod is going to be more stable than a £15 one.
I want to build a mount for my tripod, which takes a large bean bag (NOT the sort you sit on!). Nothing is more stable than your camera and lens resting on a bag of dried peas. The weight of the camera/lens is not enough for the autofocus ring to rub heavily and allow the motor to labour.
I sketched out this mount, to get an idea of sizes etc. Wifey said “Oh, nice Bird table”.
The other very stable method was the Rifle mount with the trigger adapted for a shutter release cable. I haven’t seen one for years now, maybe because in this day and age (Especially around airports / airshows) you are likely to be picked-off with a 50 calibre by our armed forces.
