fengwei, is the viewfinder frame coverage reduce with this eyepiece after magnification ?
I am thinking of getting this to help with focusing the P-M lenses... straining on my eyes when manual focusing.
Will it work on my K100D ? Thanks.
No, I don't see any loss of area or brightness after put this magnifier on. I can see the whole area as w/o it, including the infomation bar at the bottom
And yes, it'll work on your K100D.
Good luck getting one
