In reply to Robert Durran:
I have no aversion to zooming and agee that primes don't make you consider the shot more. I don't understand that ethos of getting the perfect shot from the camera either.
I do plenty of post-editing where it's worth while and crop anyway. So the suggestion of a 16mm (I own an 18mm) and an 80mm makes sense with two logical focal lengths. If I could afford a top tier zoom lens I would buy one, but with my budget and my interests in photography outside of climbing I'd much rather own two decent primes.
