This is just a dream train I wonder if anybody else has thought of.
I have shot air shows, and among the male photographers anyway, there is quite a competition before the show when everyone is unpacking their gear. The sounds of ooo's and ahhh's as an even bigger lens comes out of a bag. The white canon L lenses of course draw the most attention. But when a sigma 50-500 comes out, even though it is bigger than most of the canons, there's not a peep. So I wonder if Sigma would as an optional extra paint a 50-500 white, just to stick it to the canon boys!
And what is it about male photographers and having to have the biggest lens??
