Canon SLR Owners

I was reading The Canon EOS Digital Rebel XSi/450D Companion and there was a page where it shows you that you can remove the eyepiece and cover it with a plastic cover which is on the Strap itself. It doesn't explain or show you what it's used for and what are the benefits.

Thanks.

When you are remotely triggering the camera, or using long exposures, or the timer, you want to block light coming in the eyepiece. Whenver your eye isn't blocking the eyepiece during exposure, you want to cover it.

I never heard of that! Hmmm... I wonder if it does much?!

This. So says the manual.

Yes. If you are taking pictures with a self timer, you may need to block the eyepiece or else your exposure will not come out correctly. My old camera (T-90) had a little built in shutter for it.

IIRC the canon 1-series do too.

I've never needed to block the eyepiece, but i suggest if you need to do so that you don't do the method shown by canon. Just use a piece of black electrical tape much quicker

Normally, your eye covers that. But when on a tripod for a time exposure, it is very easy to slide on the cover attached to the neck strap. It applied to my D60, my 20D and also my 5D. It is fairly standard. Black take can leave sticky residue on the view finder glass - and sometimes black tape is not available when out in the field working.

In all honesty, I have never used it.

I know that the manual says the metering will be thrown off unless you block light from entering the eyepiece, but I've don't thousands of remote exposures without ever covering the eyepiece and things have always turned out fine.

During the exposure itself, the mirror flips up and covers the bottom of the pentaprism/pentamirror, thus preventing any light from leaking in and disrupting your exposure.

During metering, however, lots of light can and does get in through the eyepiece if your eye isn't blocking it. Try it: at least with my D90, if I have the lens cap on but don't cover the eyepiece, the meter gives me an exposure reading at higher ISOs.
