Closeable Viewfinder Eyepiece???

Is there such a thing as an aftermarket 'closable viewfinder eyepiece' for the 550D.

I know some higher end ones have a shutter that blocks them out at the flick of a switch and I'd love one for mine.

I've been searching but can't find anything. Plenty of viewfinders but none of them 'closable'.

You may already know this, but there is an eyepiece blind built into the Canon camera strap. That little piece of plastic on the strap that has nothing to do with holding the camera.

Otherwise, many use a piece of gaffer tape. Or put your hat over the camera.

Yes thanks, I've been using the one provided but a clickable one would be great for me.

One less thing for me to lose when I am out and about :)

Just stick a piece of black electrical tape to the underside of the camera body, pull it off the camera prior to mounting it on the tripod. Low tech is sometimes the best.

I throw a heavy microfiber cloth over the viewfinder for long exposures.

Baseball cap, which shades your head from the sun while walking about, serves as a sufficiently good eyepiece cover when taking a shot.

It's quite apparent there are tons of different ways to cover the eyepiece, doesn't look like there are aftermarket ones like I am after though :)

Actually, in modern day DSLR cameras, usefulness of 'closeable viewfinder eyepiece' - sophisticated, with the shutter or the simple rubber thingy supplied with the camera - is close to zero!

First, contrary to popular belief, open viewfinder does not influence exposure, no matter how long it is; it could (but not necessarily would) have the impact on metering only.

At the moment of shutter opening, mirror has already moved to the upper position, closing the light path from the viewfinder.
You can check that if you try to look through the viewfinder during the long exposure: all you'll see will be the dark frame.

Second, to mess up metering, the photographer has to:

- use one of automatic or semi-automatic modes, and
- for whatever reason, be away from the viewfinder at the moment of metering.

So, if you:

- shoot in M, or
- shoot with Live View, or even
- use semi-automatic mode but have metering and shooting separated (C.Fn. IV), have your eye on the viewfinder when metering and press Exposure Lock before leaving the viewfinder

you have nothing to worry about and you don't even need to close the viewfinder.

But, instead of trying to explain all of this to the new camera owner, it was easier for Canon just to throw into the package the stupid 'rubber thingy' and call it a day.


What we see depends mainly on what we look for.

Sadly it's a bit too expensive to be hacking about with my Dremel and making a complete arse of it anyway :)

To the untrained, I can see the logic in what you are saying.

Why do Canon go a step further than the basic 'rubber thingy' on the top models do you think?

I could be wrong, but I believe that the advanced shutter style eyepiece in higher models is just a left over from the times before Live View was introduced.

Hermeto, interesting. Your explanation makes sense. Not that I have done any scientific test, however, just because you don't see an image when shutter is activated, doesn't mean there are no light leak into the sensor.

In the early days when I was shooting with A1, it had a switch (similar to 1D) and if I forgot, I'd kick myself when the pics were developed. As a habit even today, I just cover it with a small cleaning towel.
