Hello Eric and Bob, Thanks for the great advice as usual you are a big help. I have just downloaded a sample of CNX2. As I said above, I like VNX and assume the look and feel will be similar.
I shoot quite a bit of architectural photos and I do not have a tilt/shift lens so I am interested to see how CNX2 handles perspective control. My D5100 has perspective control in camera but I am hoping CNX2 corrects it well.
