Mirror lockup on EOS 300D?

[Keltzar]

asking for a friend who bought an EOS 300D to mount on his microscope...

does the EOS300D have a mirror lockup function? I had initially thought it could do mirror pre-fire, but I can't find it...

There are no mirror lock up function for EOS 300D

its probably not necessary, if i remember correctly, as long as your shutter speed is either faster or slower than this range 1/15th - 1 sec, then mirror slap will not affect you.

and furthermore, at microscope range, it will probably have no effect, since the "shock" blur affects telephoto more. *someone tested it with a laser*

I disagree. If you think about it, microscopes and telephotos do the same thing - they magnify. Having a big slap of a mirror might upset the focus or composition or both on a precision instrument like a microscope.

The 300D does not have MLU but if you look at this Clubsnap thread it discusses a Russian firmware hack which enables mirror lockup! I have not tried this (I have a 10D) but other clubsnappers are reporting that it works.

did the russians invent other cool stuff like spot metering for 300D?

Unfortunately not. The Russian hack only re-enables what Canon has disabled.

Actually, it's not confirmed whether MLU works or not 'coz he didn't indicate it as with the others with "[WORKS]".
