anybody know the name of the little rubber plug designed to keep light leak from entering eyepiece

anybody know the name of the little rubber plug designed to keep light leak from entering eyepiece. It is usually found attached to the strap supplied with EOS cameras. The larger eyepiece can be removed and the smaller rubber plug is inserted into the view hole. During long exposures, it prevents light from leaking in via the eyepiece area

hi. The official name is "eyepiece cover". Page 23 of my manual.

Why do so many people say "FER-tographer"? Do they take "fertographs"?

Uh, clever name. lol. I've attempted to order one various times fromB&H and always end up with the standard eyepiece. Talked with customer service but they didn't seem to know what I was talking about. I wish canon would make an eyepiece with an open closed switch. I would buy that. Thanks for your help Scotty Smiley Happy

I don't think its available separately, but it comes with the strap. Under $9 at Amazon.

I've found that the cap from the lens mount works nicely. I keep a spare lens and body cap in my bag anyway.

It's called... YOUR THUMB! (That works just as well as the rubber piece. Maybe even better, since you don't need to remove the eyecup first.)

amfoto1, obviously you don't do long exposure work. Try holding your thumb over the eyepiece for 5 minutes. Not to mention what it does to the steadiness of the camera.

Body cap fits snuggly on my 6D without removing the rubber eyecup.

Lens cap fits snuggly over the rubber eye cup of my 7D.

Are you using an auto exposure mode when making a 5 minute exposure?

If using M or B mode, you really shouldn't need to cover the eyepiece. The mirror is flipped up against a light seal during exposure, blocking light from entering and reaching the sensor through the open shutter.

 

You really only need to cover the eyepiece when using one of the auto exposure modes (Tv, Av, or P), because the metering can be skewed by light entering the pentaprism via the eyepiece (when your eye isn't blocking the eyepiece). I believe the longest exposure possible on most Canon cameras using the AE modes is 30 seconds.
