One, I would like to see either the diopter moved to under the focusing knob or I would like to see a locking mechanism placed on it where it is. I hear the ZRS is going to have a locking diopter so it should not be that much of an issue to see it on the ED as well.Two, though I believe the eyecups are an upgrade from the Promasters (shape and function) I would like to see them have that feel that only the Alphas do. I am not sur if that is because most of the Alphas utilize metal in their eycup design or if they just use tighter tolerances but either way I think it greatly adds to the perception and overall level of quality. There is nothing wrong with the eyecup design now as it is entirely functional but if I wanted to improve upon something then these would be my suggestions.</blockquote>
