Mirror Lockup, Tripods, And Fast Shutterspeeds

[68lbs]

Following on from a moon thread here, I feel myself requiring more knowledge again...

Why, if you are shooting something at 1/1000 sec would you need mirror lockup and a tripod? I thought at that sort of speed you'd have to be pretty heavy fisted to blur the pic. And why does the fact the moon is so far away make a difference. I understand that longer focal length, the more pronounced camera shake is, but don't quite get this comment.

I think the combination of all the above help you get a fairly decent shot of the moon. I've tried out various methods, and the setup you mention gives me my best results.

Mirror lock up is used to reduce camera shake when used on a tripod.

When you press the shutter release it moves the mirror up, pauses, and then opens & closes the shutter. The delay between the mirror being moved and the shutter eliminates any chance of movement due to the mirror moving.

This may sound odd, but I would think the quicker the shutter speed is 1/1000 (for example) then the more effect shake could have compared to a long shutter speed say of say 1 second, as it has less time to capture the image.

With a long exposure it is possible to see the movement of the moon, but I can't see why 1/1000th should be necessary. It doesn't move that fast...

Otherwise I would have thought a tripod would do the trick.

Mind you, I don't think I've ever tried it myself ....

I don't use mirror lockup but I do use a sturdy tripod and a remote release.
My photos are usually bracketed at 1/250 at iso200 on a 10D.

I thought mirror lock up was best used in that shaky range especially below 1/15 to about 1/2 but then again that is for macro. At 1/1000th would it be quick enough to have an effect - I do not think so but could be corrected...:shrug:

TBH.. I would use a tripod and slower shutter speed around 1/250 with low ISO and mirror lock up but at 1/1000 I really can't see the point of locking up the mirror?

if hand holding, you won't see anything with the mirror up anyway so why bother :shrug:

HTH.....
