Thanks for the comments guys.
As most people have suggested, I just let it brush off my shoulder. It didn't bother me a bit and certainly wasn't worth an iota getting into a “stick-measuring” competition over it. Besides, these are actually nice people and just got me off guard with their comments. For anyone wondering, the “pro” guy who did the studio pictures didn't sell much of his work. A handful of students only, out of at least fifty students total. I've heard people commenting on how expensive his package was but photos weren't that good. I actually felt kind of sorry for him at the end.
I'm fairly new to the dslr world in comparison to other members here. I chose Pentax (K-x when it was introduced) because I did my research, read tons of reviews and comparisons of relevant brand and models, lenses, weigh my options and evaluate my needs. Pentax always came out on top at every angle for me and never regretting the decision.
I love my K5 and very nearly pulled the trigger on the K5IIs when it dropped to $496. Held back after the announcement of the full-frame. Skipped the K3 as well but the 3II, is “enticing”.
My wife is toying about the idea of photography and got her a used K-r. My 9 year old is showing interest as well, got a second used k-r for him (he doesn't know yet). Will I continue to shoot my Pentax K5 (and K-01, DA18-135, DA35 and DA* lenses)? Absolutely!
