It's a hobby for me too. I've always dreamed of owning a tilt shift lens. My other hobby is motorcycles and I was going to buy a dedicated track bike in addition to my street bike, but went a little bonkers for photography instead. I figure I can get the track bike in a few months but I can enjoy my new camera and lenses any time I want until then.
i started a year ago this month and i haven't kept records but just adding up what i can i've got a little over 12K in it right now. it's a terrible addiction, the car and deer season are the only things holding me back right now.
i was negotiating a trade with a guy for a 400 f/2.8 last week and i talked myself out of the deal. i started out with plans of shooting wildlife and i do at times but i don't need that lens.
i'm a little compulsive and impulsive when it comes to my hobbies. i don't always use good judgement.
