I'm not sniping, but I find the price quoted for the A a bit high end. It is a bits system, and finding the other bits is feasible as you go. I pick up an A filter or two as I find them at camera shows, a lot for the history perspective to educate those of the D age of how effects were achieved before PS came along.

There is a reason I put that there.
