What do people think about zoom lenses? I hate them and dont use them. My main reasons are not only the loss of quality compared to fixed focal lengths, but mainly because fixed focal lengths provide a better learning curve for appreciation of perspective control. Look at this HCB shot
and how by creating the right camera to subject distance he was able to match the angle of the line on the wall with the angle of the cart. However, I suppose if you use a zoom lens at specific focal lengths for what you are trying to achieve, it achieves what you have in mind.
Don't know if it's a fact, but when I was building my Canon 35mm system 25 years ago during Canon FD days, I was told that prime lenses are sharper than zoom lenses. I didn't own one FD zoom. I find today's zoom lenses are good as prime lenses. Does anybody know if I'm full of it?
While one can measure the difference in the laboratory, one would be very hard put to pick up a print or look at a slide and definitively say that it was taken with a prime lens or a zoom lens.

I think the quality of lens technology n glass has improved over the years so zooms aren't as bad as they once were.. altough still slower than primes.
I'd say you'd have trouble finding differences in picture quality.
New zooms are much better. Superzooms now will have some vignetting and pincushion at some lengths. Old zooms had more chromatic abberation than prime lenses. Most zooms made in the past ten years are pretty decent, except for some of the super zooms.
I mostly use prime lenses as I like the bigger apertures and can zoom with my feet just fine much of the time.
If someone is too much of a snob to use a Nikon EDIF 80-200/2.8 AFS or a 70-200/2.8 AFS or 70-300 ED, I'll take it off your hands so you can have your credibility back.
My thinking, usually, is that I'd rather spend money on optics than mechanics. Modern zoom lenses can be really, really good, but all other things being equal they tend to be more expensive than comparably good primes.
That said, I've got a Kiron zoom lens in FD mount that I just love. (On the other hand, I believe it cost me US$8.99, so it's a pretty clear exception to the rule above!)
I don't use them because they are too big. I had couple of nikkors (28-80, 80-200/4) - they were good optically, but the size is just too big, and with fix lens I get f2 or better and with zoom f4 or f5.6.
