If it's a hobby then it's up to you how you enjoy it, same as any other hobby I guess. I'm also a pen-thusiast and the fountain pen forums get plenty volatile sometimes with the same old brand wars. I suppose the easy thing there is it's less expensive to spread yourself around a bit, a first foray into Chinese made pens got me a nice little writer for £1.98 inc. delivery. Not so easy trying another camera brand...

Back on topic the only other 'photographer' I could name is Dr. Paul Koudounaris, but pretty much anything concerning death fascinates me anyway - unlike most I look forward to it - but I'm in no hurry to get there either! Only wish I'd had my K50 when I shot the attached, never did get a chance to go back and the ghosting bugs the hell out of me.
