It seems to me there's a certain sentiment that zooms are bad. I, and seemingly many people in this thread, disagree.
The difference between a good prime (not GREAT, which costs half your life savings) and a good zoom at the same settings is not very noticable. For most people you would be hard pressed to put two photos side by side and make a blind taste test (so to speak) and put your finger on which was the zoom and which the prime...
(by "good" I mean not the bottom of the barrel crap lenses that will always have problems, but nothing that breaks the bank either. Good middle range gear.)
IMO, and mind you I could be wrong but this is honestly what I feel, the one area where a prime will be better is under intense scrutiny, using much higher magnification than average. This is useful for primes where you have to then blow up your own prints to get the original framing you wanted. But.... a zoom removes that need (for the most part). With a zoom you can get the exact framing you need the first time. Your quality is still good enough to blow a photo up after the fact to make larger prints.
I have a decent 50mm (stock Canon, nothing bad, nothing great) that I used a lot. I have a 28mm I also used a lot. The problem is the framing of the shot I want. Having to choose the lesser of 2 undesirable shots to get what I want. I find my main choice these days is a Sigma 35-70mm f2.8 and it saves a lot of time I used to spend swapping out parts. Not the best, not the worst. Good mid-range quality glass. I'd challenge folks to find a flaw in the pictures taken with it -- a flaw that wasn't user error, mind you -- compared to my 50mm.
