Could be!

I did find that with the E-1 and the 50 F1.4 lens, focus is off by
about 3cm at 3m. When I tried my very hardest to get the focus exact
using the viewfinder, that was the result in the image file. 3cm at 3m
is a 1% error?  Hmm... And here I was getting all upset about it.
Just stop shooting wide-open.
