i've put three or four rolls thru the Zuiko 24mm, i like the tilt i get from a 28mm, and the 24mm is more fun that way. perhaps there are computer programs that can correct for wide-angle distortion and i'll stubbornly stay away from corrections-programs.genius. My mind sees those perfectly vertical lines at the left and gets really confused about all the tilting elsewhere. Really, whats up with that???
