ok im very very jealous i only have a 200mm for the minolta and a 210mm for the pentax
I blew my bonus a couple of years ago on this, and a Canon F1-n to go with it. Had to convince you-know-who a bit, especially since this was the most expensive lens I've bought (so far). What I would really like is to be able to put it to good use.
Tamrac has some large backpacks with adjustable inserts as well as being comfortable. I have been very pleased with mine but use it for medium format equipment and it holds a lot and keeps them dry. They also ha add-on accessories. i would think they have a website that would give dimensions of their products.
