you slowly start buying gear and one day your gear is more expensive than your first car.
…and then one day, you buy a single lens that is more expsnsive than your first car.
I got a really, really good deal on my first car (a pre-owned Ford Escort), so I crossed that limit when I bought the 17-85mm IS USM for $ 325
To answer the OP:
5DIII- 2450 (actually paid)
24-70 II- 1550 (actually paid)
70-200 II- 1700 (actually paid)
35mm A- 700 (actually paid)
135mm L- 700 (refurb 20% disc)
17mm TS-E- 1600 (refurb 20% disc)
Gitzo 2541- 550 (actually paid)
Arca Swiss Z1- 300 (actually paid)
600EX-RT x 2- 700 (refurb 20% disc)
Overshoots by $ 250, but whatever.
This was a really good exercise, because I own most of these except the 17mm TS-E and the extra 600mm, which means I did use my money wisely so far. Lots of buying and selling on the way, and lots of lucky deals. But I am at a happy place
Also means I have $ 8K of equipment just for hobby. WTF!!!
