screen shade for 1d mk3

Anyone know of and tried bellows type for this camera. I like it on my mk2.?

i thought about getting this for my MKIII, but ended up w/ a clear screen film protector instead. I found that if you forget to close the LCD cover, I frequently jam the cover into my eye. Then again ... that's just me, careless.

That's why I went with the bellows one and have it squashed right in. It just gives a little shade to help in bright light.
Havne't bought the mk 3 .. yet but it's just as hard to see in bright conditions despite the large 3 inch size.
I'm just wondering whether it's possible to use on this camera. Camera bellows doesn't seem to make one 3".
