Got this a few weeks back as I thought it would just extend out the viewfinder so I would not get marks on my screen and flash unit, well it does that OK, but it also makes the image a different size in the viewfinder. That I don’t want it to do.
Can it be modified to not change the size?
Is it me or does it make the image seem smaller?
Anyone else not happy with theirs?
The shop never told me it did that.

Real thing would be eyepiece extender that makes image larger.
