I have been using the selftimer quite alot while shooting nightshoots and most of the time i have been anoyed with the fact that the timer takes 10 seconds to deploy.
When using the timer as ment to in self portraits its no problem but when using it as a substitute for a remote is quite anoying.
After reading alot on this board i figured i would give mirror lock up a try to see if there where any improvements in my images, so off i went and set the camera up on my tripod, and set the drivemode to timer..
Now the timer only takes about one second to deploy when used in conjunction with the mirror lock up, this is not a feature i noticed while reading the manual for the camera.
Im not saying its not in the manual, im just saying it wasent something i noticed while reading it
So timer and mirror lock up equals a one second or so timer instead of the usual 10 seconds.
And yes, a remote is on my shoppinglist just after i get myself a good CF tripod and a good ballhead to go with it
