Oh I just saw this. I don't really see the glare. It does seem to have some areas that are soft, looking at the preview. Other areas are sharp. Stopping down the lens will usually get the whole thing in focus. Still I am pretty sure I would pass this one at the 48 inch size, if I was on the review team ;-)
Oh yes and keeping the light sources way off to the side as mentioned is the fix for glare for flat art.
