^^ Yeah, the prime slide is nasty.
@OP - Glad you're happy. Bad news, now you're hooked.
Next, you will go look at the 200 f/2 thread, the 300 f/2.8 thread, and the 135 f/2, and the 85....
After that, you'll be calculating new credit card payments, or explaining why you didn't buy an RV instead.
And once you hit that level, you find these odd ideas, like manual focus primes by exotic names such as Zeiss, followed by something called a tilt-shift, like a 17 or a 90, by which time you want good lights, and something called a pocket wizard, right around the same time you find yourself thinking about which light (sabre) meter to buy.
Only then will you be a jedi.
And broke.
Congratulations on your first purchase on the road to enlightenment (sic).
