Interesting thoughts. The 3 primes (85, 100 and 135) did cross my mind several times. Perhaps its a good idea to buy used but in good condition and try them out, and sell it off later if not used much.
85L II + 70-200 f2.8 IS II are my fav for indoor portrait.
24-70 II + 135L is not a bad combo at all. Photo below was taken with 135L @ wide open.
Dylan, beautiful photo! I know you recently bought the 135, and you also have the 85. Right off the bat, what did you like most about the 135 over the 85?
The recent thread regarding the 14-24 and 16-50 lenses got me all excited, though it's still a rumor. I know I will definitely jump for the 16-50 (prefer non bulbous front element) if it's released and as stellar as the new 24-70 II or if it's mid frame is substantially better than the 16-35 II. Till then 16-35 II stays. Upgrading to 24-70 II just got more confusing if 16-50 is indeed in the works.
Upgrade the 24-70.
Give the 135L a try (I love mine....)
Are you a strobist? Take a look on a pair of 600rt's.
Choices. Have more fun than headache!
I am no strobist but I am trying to learn the art whenever I get the chance. Have not yet experimented with multiple flash.
