Shortly about to upgrade the 7D to a 5DIII and (probably because it's bundled with one) a 24-105 f4.
Will probably sell the 7D and 18-135, but will keep the 100-400L
Also looking at a Sigma 50mm f1.4
Anyone used these lenses on the 5DIII and can give feedback re usability, fit for purpose, quality etc?
Not doing much motorsport now so long reach and high frame rate not so necessary, more interested in FF and a nice 50mm for street stuff...
