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.
My 5D III cost the same (number of dollars) as my first car. The camera $3500, the new 1964 Pontiac GTO convert. w/ 4 speed, tri-power, posi rear axle, power steering & brakes and lots of small add-on things was around $3475.
Just thinking what the 500 f/4L at about $6200 would have bought back then.
