So, if you try something new, try it in your hands before you sell the old gear, at the least.
Yeah, actually I've been to my local Fry's and Best Buy to handle a lot of the NEX cameras. I knew that the C3 has been discontinued so the next best thing was the F3 and I actually liked the small format of the camera. It's smaller that I wished it was, but I liked the portability.
Yes ... You are crazy to sell your Canon gear ... Especially because two months back you were seeking advice as to how to improve your gear -
Give it 6 months and if you don't find yourself craving for the DSLR IQ, Sell your gear.
+1. Give it some time and live with your gear.
+1 Give you current gear at least 6-9 months before moving in a different direction. If you have only had your 5Dc for 2 months, that's not enough time for a real evaluation.
I have been using my 5Dc for a few months now. I love it and I don't think I will not let go of it, but I'm kind of tired of lugging a huge DSLR around everywhere. I'm not getting compensated in anyway for my photos,. But I understand that gear is just tools for photographers, and i think smaller gears will be better for now.
You did not mention the kind of photography you do.
Decision depends on that.
+1. If you like the creativity of thin DoF, stick with FF.
Sorry, I didn't realize I didn't include that: Landscapes, Still Life, Group Shots and Portraits (Candid Portraits)
