JJC 2-Pack Eyecup Eyepiece Eye Cup Viewfinder for Canon EOS 5D Mark IV 5D Mark III 5DS R 5DS 7D 7D Mark II 1Dx Mark III 1Dx Mark II 1Ds Mark III 1D Mark IV 1D Mark III Camera, Replaces Canon Eg Eyecup

Fits the 1dx perfectly. Worth noting however, it does block access to the diopter adjustment wheel. Otherwise, excellent product.

Perfect fit to replace the old eye cup for my Canon 5D Mark IV.

They are easy on the eyes, my issue though is that they don't truly snap into place. It keeps launching off at the slightest movement (I do concert photography) and being all black it is hard to find. Maybe it is just my rangefinder.

Bought as a replacement for a canon 7dmii- slides on fine, not quite the same fit or shape as canon brand, but only I notice. Works and feels fine and like original eye piece

This eyepiece for the 1DX Mark II does not snap in place and I have had tons of trouble with the thing simply sliding off the camera. It does fit the slide dimensions but does not have the mechanism that latches it in place. These eyepieces are going in the trash, unusable due to the lack of ability to secure to the camera.

Great value for what it does. Why spend $20 for a canon one when this is just as good? No jiggle—tight snap fit.

The eye cups fit snuggly, but they do not lock on like the Canon brand. So, they are subject to slipping off with use.

I bought this eyepiece to convert to a black-out cover for long exposures. The eyepiece cover provided by Canon is very small and isn't as easy to use.This came as a two-pack and I keep one as a spare just in case I lose the OEM part.

exactly right fit for my ds1 mk3.very satisfied! 2 in package. fast delivery.

Great fit and Price

Does not lock into place like the Canon brand. Easy to knock off by accident, but some double-sided tape fixes this. Decent for the price.

Does what it it say it will do on their web site but again its from..........

compatibile, e perfetto , ma non ha il blocco come l`originale, quindi si sfila di continuo
