Oh hell's no! That camera hasta' go baaaaaack to the un-minty seller's casa!!!
(A nit: I don't know that the
seller is un-minty, but this camera body certainly is

.)
Now...I really thought the LCD screen on the 20D and 5D I own is/was solid glass, not plastic. There are plastic covers for the LCD screens for most d-slrs...I take those and throw them in a drawer,and use the rear LCD the way it was born: buck nekkid!
Do you mean the protective film that most virgin displays sport? That most people peel off and toss? Kind of like screen protectors, but not quite as nice?
It looks like the 20D a buddy gave me still has those on it. They're actually in better condition than the "glass" on this 40D! So I'm leaving them on it.
So...on this not-mint 40D...is the rear LCD's actual glass the issue? Or is it the $10 plastic LCD cover that snaps on over the glass?
There is nothing I can tell that's snapped-on to the screen. Looks like nekkid glass. Except... is it really
glass, or simply scratch-resistant plastic? (I suspect the latter.)
(N.B.: The discussion is academic at this point, as I've already decided to return the item. Just letting my missive to the seller sit and "perk" for a bit, before reviewing it a last time and sending it off.)
If it's glass, won't do a thing but make a mess. If it has a plastic cover, he has OCD and is far sighted....
I
do have OCD (think something along the lines of Sheldon Cooper, but not
quite that bad), and I use both reading glasses
and driving glasses. (Too many years spent staring at computer screens precisely an arm's length away, I suppose.) But I have examined the offending surfaces in detail, with the aid of eyewear, and am certain the unsatisfactory condition is, in fact, on the "glass."
