Sigma 500 f4 sports
After a bit of a lens conundrum I finally landed on a sigma 500 f4 sports lens. I have to say that this lens is sharp, easily sharper wide open than my canon 400 2.8 wide open, the canon stopped down and they are probably almost even giving a slight edge to the 400 which is impressive, really impressive as that canon could slice butter. It took me a few lenses to get here, canon 500 f4 IS and canon 600 f4 IS which I was totally underwhelmed by especially as all I read is how fantastic they are, both pretty poor wide open (Remember I’m comparing those both to the 400 2.8). For me a lens has to optically perform wide open or I may as-well get a zoom and save money. Then we get to the af performance, all three of the canons where poor with the older non IS 400 2.8 performing better than the two newer 500 and 600 IS models. The 500 and 600 where so bad I started to manual focus! The sigma with the sigma adapter for the Sony is such an improvement over the canon, even appears to track, no where near sony level.
