Hello,

some weeks after getting my EX1 I discovered a brownish shaddow in my viewfinder. Its not visible on display or recorded on footage. It is definetly somewhere in the upper part of vf/the glasses, because one can move the head/eye and the shaddow will slide away. I never use viewfinder (film at night on tripod only) so I almost never look into it - that's why I noticed it so late.
The shaddow is clearly visible when connected to USB or in thumbnail menu (black background), but it is (almost?!) not visible when filming.

Is this somehow normal and if not, what caused it? Will changing the vf-glass remove it? For what costs I should prepare when changing the glass/vf?

I myself do not care about it, but I will sell EX1 for EX1R and fear the questions of the new owner...

Thanks a lot,
attached two photos to show the shaddow and the different positions at a different views.

If it moves relative to the screen as you change viewing angle then it's in/on the optics. Probably just dirt.

Thanks Alister.
Yes, I assume its not a big thing, but its no dirt one could wipe away from outside. So it seems to be something in the optics glass or between different glasses in vf. The strange thing is, that its a "optically bend" shaddow, somehow the shape like a rainbow beam - its no "blob" of dirt.

I will check manual if one can take viewfinder off and polish all sides of glass.
