Hee. My problem lately is that I take my sense of the horizontal for *granted* too much, and I've been using this EVF camera with a bit of a laggy finder and some barrel distortion at the wide end of an otherwise excellent lens: (I'll take that barrel distortion over not-sharp-wide-open any day) I started getting some film back after a while of that and was like, 'WTF, did I pick up a bad habit somewhere?
'
I discovered, when I put a waistlevel finder on my Mamiya, that my hands had picked up quite a little habit for overcorrecting.
