I've owned a 550D since its launch and I am beginning to get very serious about my photography. I'm looking to go from being a hobbyist to at least a part-time paid shooter. My main focus is landscape, portraits, events, and documentary film work. I don't shoot sports very often, but it's one of those things where when I do need good AF, I want it there.
My glass consists of a EF 50 1.4, EF 24-105, and a Tokina 11-16. My budget is 3.5k... the price of a MIII.
My question to you all is would it better to put all of my money towards the MIII, or a MII and a lens like the 70-200 2.8? I plan on selling my 550D+Grip to contribute towards this purchase. I feel like the MIII would be a better investment in the long run, but more glass is always nice.
I know there were a lot of words in there, but I appreciate any advice you can give a fellow photographer! If there is any other info you need about my needs/shooting style, let me know!
