>>3634311Reminder that that Sigma lens is slightly sharper at 500mm and f9-f11 than at full 600mm. Also, for some reason, the Contemporary version is minutely sharper than the Sport (which is also much heavier, but sturdier. And more expensive.)
I really do like mine, and it's a marvel how well it performs, especially as a big-zoom lens, when I compare proportions and weight to my 500mm prime.
