Avoid wearing red garments with orange logos (or vice-versa)..... too clashy. (This tip was provided to me by my daughter, who knows nothing about photography, but a good deal about fashion..... or so she says).

And, no, I do not black out the logo on the camera - but I do use an unobtrusive non-labeled bag.
I wouldn't likely black out the logo. For starters, I'd feel like an 80's movie extra. Also, Pentax isn't currently a brand anyone's targeting, to my knowing, so why leave anyone who cares guessing. (As for whether or not anyone can tell my old Canon film cameras from a DSLR might be a more worrisome question.
I would like a Pentax ball cap but not in a one size fits all. I would like one that comfortably fits a fat head like your's truly...a 7 3/4 size...those one size fit all...perch on top of my head...if I try to force them down...they make me dizzy...I guess they're cutting off the circulation to that big brain of mine...
Wouldn't it be a nice touch if inside every new DSLR box and new LENS box was a Pentax branded lens cleaning cloth...or two.
Would cost them bugger all and be a very useful addition.
