Hi
Canon XTi (EOS-400D)
Can someone explain the Mirror feature on the camera as well as with a lens.:confused:
I have this feature and don't know what it does or when to use it.
I'd much appreciate the info.

You've lost me there :) :confused:
Can you explain further? Do you mean 'mirror lens' - a compact telephoto lens type?

Do you mean the mirror inside the lens mount? If so, this allows the light coming in through the lens to be reflected up through a prism and through the viewfinder so you can see what you are looking at. This is the Single Lens Relex bit of the dSLR nomenclature. When you press the shutter release the mirror pops up and the shutter opens allowing light to fall on the sensor.

Ah - yes, of course :D
Couldn't see the wood for the trees with that one *LOL

Just found this in the manual, but I'm still not too sure about it:
Mirror Lock Up...Although remote control shooting can prevent camera shake, using mirror lockup to prevent camera vibrations can also help when you use a super telephoto or shoot close ups.

I wouldn't touch it personally. Especially at that price, but more importantly because the max aperture is F8 and at this the camera will struggle to focus in low contrast scenes.
I also have the 400D but have never used the mirror lockup method for taking photographs.
Firstly you would have to delve into the menu to enable the mirror lockup function. To actually use it you need to press the shutter down completely. This does not take a photograph, it locks the mirror in the upward position.. You then need to compose your image via the viewfinder and take your picture. The mirror will then return to it's original posiiton and you have to go through the whole procedure again.
The claim is that it will help to reduce camera shake.
Personally I think you will be better off casting this from your mind. You can reduce/eliminate camera shake by using a tripod or resting the camera on or up aginst a solid surface with better and faster results.
By all means experiment but I think you will find that it is to much trouble for little gain.
I think a quick read here will answer your question. http://www.luminous-landscape.com/tutorials/understanding-series/mirror-lock.shtml
