I have to say I'm a little disappointed. Canon still don't have a built-in eyepiece cover for the 5D line like the Nikon D700 - making you use that S___ty little rubber eyepiece cover that might be attached to your neck strap, if you use a neck strap.
First chink the armor.
GRRRRRRR!!!!!
ummm... are you serious? As a professional, I cant say i've ever in the last decade thought in the back of my mind... I wish my camera had an eyepiece cover... Never... Not once... I think it could be a nuisance more than anything else... when I want my camera ready to shoot, it better be ready to shoot... If any dust gets in the peice, I'll take a qtip and clean it... done.
It's bad for metering when not using it up to your eye.
These days I tend to do most of that sort of shooting with liveview so it's not so much of an issue.
+1. I have not noticed a problem. I do meter with my eye up against the eyepiece, and for most of my landscapes when on a tripod-I'm in liveview and a 2 second timer so the mirror locks up and I have already focused (sometimes manual sometimes from the back of the camera) and metered just before taking the shot. But then again I am more of an enthusiast than a pro photog.
That's how I shoot... however live view use is mainly on tripod, when I want to evaluate the full frame (xxd and 5d VF isn't 100% at this time) When I use the 7d, because it's 100%, i hardly ever used LV to be honest unless shooting video or when i needed an angle where I couldn't be using the VF... I've never really had light meter problems as I either independently meter, use an educated guess based off of sunny 16, compensation, and experience, or if I need the camera meter, gray card and bring up the exposure to middle.
