About Canon EG

In cold or humid weather the Anti-Fog Eyepiece Eg accessory attaches easily to reduce condensation and help you maintain a clear view of your subject.

When warm air touches cold glass, moisture in the air is condensed. Camera and binocular finders are no exception. In photographing at a cold place of ski or skate, the breathing of a cameraman or moisture transpired from his/her eyes dims the finder.

For this reason, you cannot concentrate your attention on photographing or miss a decisive moment, and it was a troublesome problem for professional cameramen who are required to perform accurate photographing all the time. The anti-fogging eyepiece was developed to solve such problems. Subsequently, eyepieces for binoculars were also marketed and are demonstrating their effectiveness for bird watching, astronomical observation and other activities.

As the conventional anti-fogging technique, methods of drying with a hot-wire heater and of coating with a surface active agent such as wax are available. But these methods cannot be used for optical products because of such problems as surface accuracy and durability. The anti-fogging technology developed by Canon is to absorb moisture with a thin membrane of moisture absorbing polymer formed on the glass surface. Since it maintains a stable state with almost no physical change, it is optimum for application to optical products. Although the amount of absorbed moisture is limited, moisture naturally evaporates. Through repeated moisture absorbing and transpiring, it maintains the anti-fogging effect for a long time.

Works Great but Try Cleaning it!

Very expensive price for an item that can not really be cleaned well-the coating is easily removed and then you have to buy a new one.

Stock Canon Eyecup


from Florida  -  Professional

Replaced a part with 7 years of field time. The rubber eye cup eventually wears out but is a simple replacement with this producy


Product was as expected


from Hawaii  -  Hobbyist/Enthusiast

Product received was a genuine Canon product as expected.


Canon reliable quality.


from Tucson, Az.  -  Semi-Professional

I'm a sports photographer for a major university. I typically use two Canon 7D's at an event. I used an aftermarket eyepiece and it fell off the first time out and I lost it. The Canon replacement has been through a few events now and had remained in place. Lesson to be learned. Put a Canon on your Canon.


It's also the OEM Eyecup for the EOS 7D


from Sonora/Modesto/Hayward, CA  -  Semi-Professional

When you take your EOS 7D out the morning after an all-night shoot in a dark nightclub only to find the eycup is missing, you can order another one exactly like the one you lost. This is it. It not only fits the 5D and the 1, it fits the 7D. So, if you lose the eycup for your 7D, this is the replacement.

Perfect Fit - OEM Eyecup


from Wichita Falls, TX  -  Semi-Professional

It fit my EOS 7D perfectly. I actually use this as a viewfinder blind by modifying it with black plastic and metal tape (to protect bleedthrough shooting Infrared pictures.) It works much better than the flimsy rubber blind that came with the camera and is much easier to use. Just slide the original and slide this one in its place.
