I wish Canon would make one of these: a 400 F4 IS, not DO, designed for ASP-C. Hopefully it would be inexpensive (comparitively; I wouldn't mind 1,500-1,900). Though EF-S would probably make it incompatible with TC's, so hopefully they could make it ASP-C but not EF-S?
Is this a crazy idea? Or would others buy this too?
