Anyone with a DSLR will be in the minority, but the brand will skew the percentages simply because of the small sample size. Case in point: I brought my K-7 to my son's wedding this past weekend. The professionals had a C & a N, so Pentax was fully one-third of the DSLR's present! 'Course I wasn't fooled by this math, but I was happy to show my brand along with the full-frames.
I can't wait to see how their pix turned out, obviously from a father's perspective, but also to compare with my meager attempts.
