Mirror lockup is used to reduce vibrations with longer exposures. When the mirror folds up, the camera shakes for a bit. For short exposure times this doesn't matter, but for times of a few seconds it will cause motion blur. By locking up the mirror before, the camera will be still for the exposure.

Mirror lockup can function in a couple of different ways, depending on the camera: Mirror lockup with self-timer - when you press the shutter release button, the mirror flaps up immediately. The image is taken after the timer interval has passed (typically somewhere between 2 and 10 seconds, often configurable in the camera). Mirror lockup without ...

First of all, what you have is probably mirror pre-fire rather than a true mirror lockup. Only a few cameras have ever had a true mirror lockup, and I don't know of anything current that does. With a true mirror lockup, you lock up the mirror, and it stays up until you unlock it. This can be used in the same cases as mirror pre-fire to reduce camera shake. ...

The D80 has an Exposure Delay mode, which basically adds a 0.4 seconds delay after opening the mirror, then automatically starts the exposure. So it's not a manual step, but just an automatic mirror lockup. From a quick Google I think it's custom menu open 31.

Mirror lockup will move the mirror out of the way, pause (often around 2 seconds), and then acutate the shutter. This will reduce shake in the camera as a function of the mirror slap and can substantially help sharpness for very long lenses, macro work, and long exposures where the shake from the slap can become apparent in the result.

The only way to do what you want with every Canon DSLR I've ever tried is to use Live View. Since the 350D does not include Live view, I would assume it is not possible with that model. I have not tried it, but I believe Magic Lantern adds this capability to some Canon models. I don't know if that includes the 350D/Rebel XT. As an aside, I do bracketed ...

The wired remote will function just like the shutter button on the camera: A half press will activate metering and/or focus (depending on how your custom functions are set), the first full press will lock up the mirror. The second full press will then open the shutter to expose the image. Just as with the shutter button on the camera, if you press once to ...

My understanding of pages 152-153 of your manual is that you have to capture the correct number of frames (2 or 3 as chosen in the menu) in order for the "multiple exposure" sequence to be complete. As @alen mentions in his comment above, burst modes will mean those 2-3 frames are captured relatively quickly, but in other shooting modes, you still have to ...

This is what I do or at least tried and it works. I have a Canon 450D DSLR. I enable mirror lock up in the camera functions. Now on my 3rd party timer remote I set the delay for 10 seconds with say 1 minute exposures (I do fixed tripod astrophotography using a barn door tracker on my tripod and the camera on a ball mount attached to the barn door tracker) ...

It partly depends on which wireless remote you are using. RC-1 and RC-6 are capable of shooting without a delay or after a 2 second delay. RC-5 is only capable of shooting after a 2 second delay. If you set the Drive Mode to 2 second delay they should all work the same way. If the Drive mode is set to 2 second delay, when you press the remote button the ...

Once you enable the mirror lockup in the custom functions, it should wait for 2 seconds even if you use the remote. See the Manual: With Remote Controller RC-6 (sold separately) set to a 2-sec. delay, press the transmit button and the mirror will lockup before the picture is taken 2 sec. later. If it shoots immediately, you need to set it to the 2-sec ...

No you can't. It is only for cleaning the sensor. If you want to do long exposure shot, you can select the manual mode and roll the rear wheel in 'bulb mode' (after 30").

Mirror lockup is most useful when using a very long telephoto lens or when doing high magnification macro work. Because the field of view in these cases is limited to a very small angle, they are the two situations that are most likely to result in vibration caused by the mirror to be visible in the exposure. As others have mentioned, the camera should be ...
