I'm sitting here with a 17-40 and 85 1.8 as my normal combination. I've got a 24 2.8 as my mini walkaround lens. I've got a 70-200 4 as my long lens. All on a Rebel D. As the gap between 40 and 85 is a fairly significant one I'd like to fill it with a prime (no more zooms wanted at all).
I've previously had a 50 1.8 and was pretty bored with it and used the 85 instead. I'd like a little better low light ability (the 1.4) and also some macro ability (the 2.5). Can't make up my mind though to go for the fast 1.4 or the multipurpose 2.5. I'd like thoughts on either please, particularly the 2.5 as there isn't too much info out there on it.
And no, I really don't want another 50 1.8
Thanks in advance
