A search revealed lots of informed speculation but not much experience from actual users. I have a new Ebony 45RW and am wonder what the lens limits are at both the short and long ends. The Ebony website gives "usable" ranges from 65 to 500mm, but this clearly isn't the case. I'd like to get an 80mm, but are there photographers out there who have actually used a lens shorter than 90 on this camera. Same question for the long end. I'd like to get out with a 400mm, but is this too long? Thanks.
