Thank you, thank you, THANK you for this.
I've been debating for two months how to best improve my camera kit. I'm a self-taught photographer and professional environmental journalist, who's primarily focused on shooting animals and people in nature. After a year and a half spent cutting my teeth on a kit lens and Canon T3i (to ensure I spent my time honing my eye for composition and basic understandings of light and timing, instead of fretting about gear), I'm finally ready to shoot on a more advanced setup. Every professional photographer I ask about gear derides me for even bothering to think about gear, saying, "Only amateurs worry about gear," but I think exploring all my gear options is an essential part of learning how the components of cameras work together and why. I've been debating whether to get a 6D, simply invest in better glass and give my T3i its due, or chuck Canon altogether and go for a super expensive but portable Sony A7s (great for lowlight, but mirrorless, which can be an awkward transition—I feel more connected to the photo when I see it through the lensfinder). Your review makes me feel like I should really just shell out for the Mark III, but I'm worried that after dragging my feet for so long, I might be better off waiting until the next iteration of the camera comes out, so I miiiiiight be able to find Mark III's at better prices. But I won a scholarship to Santa Fe Photographic Workshops for a workshop in July, so I probably need a good one now (it's an action-oriented workshop).
Some photographers I've spoken with have been saying they think the 6D's sensor is better: would love to hear your comments on why that is/isn't true, and how.
Anyway, that's a lot of personal info but, TL;DR: THANK YOU.
