The Sigma 70mm macro and 50mm f/1.4 are compatible with FF. The 30mm f/1.4 is a DC lens, meaning APS-C only.

Given that, reducing your MP count at the same time as reducing or eliminating the 'crop factor' seems like a one-two punch on IQ.


I'd say your best bet would be a used 50D - you keep live view and AFMA, similar ergonomics, still 1.6x crop, APS-C-only lens compatibility, and only lose 3 MP.


Good luck!
