The cap looks great, but i really wish they had black polos.
I would not care about the temperature wearing it, as long as it was simple as the cap.
I would prefer a White Polo with the red Pentax logo, would look great on the golf course But would still buy a black one if that was all that's for sale....
How about a baseball cap that 'flips up' when you want to take a shot.
A Pentax badged Subaru, (it worked for LL Bean), it could have a panel on the roof that you could stand on with a hole in it and the rails to secure a tripod.
Pentax Body Armour, for the war photogs out there.
The Pentax Limited Series G-String: combining great aesthetics, superb construction, and a tiny size. I'd wear it. In fact, I'm wearing a prototype right now.
And a second on the watch. If it's analogue, make it proper analogue - preferably automatic, not quartz. Chronograph if possible, for precisely timing those longer exposures.
Crystal should be SMC coated, of course. And water resistant, to fifty metres - to go with the weather sealing, of course.
If it's digital, I'm sure Pentax can fit a 1-degree spot meter in there. It's Pentax, dammit. If they can't fit a spot meter into something the size of a small stack of coins, then no one can.
