What keeps me in APS-C?
- The Sigma 18-35 lens is exceedingly good and convenient, and there is no affordable, high-IQ equivalent for FF (is there? I am pretty sure there ain't). There just isn't a convincing and relatively affordable 28-55 f/2.8, bitingly-sharp-and-contrasty-from-the-get-go-at-all-FL zoom for FF out there.
- My work takes me to several dicey locations. I can stand to lose the 650D due to theft or damage, but it would be a more bitter pill to swallow for the 6D.
