As a former DSLR owner I generally used zooms. I'd use fast primes when f2.8 wasn't fast enough but preferred to use zooms because any time you change a lens on a DSLR is a chance for getting dust on the sensor. I have an 80-200 f2.8 Nikon and a Sigma 10-20 and (had) a Tokina 28-80 f2.8. All are great lenses, especially the Nikon and the Tokina (although the reviews here on it wouldn't lead you to believe it). The Sigma is no slouch either, and the image quality is very impressive for a 10-20mm lens that's as small and inexpensive as it is.

The only lens I had problems with on my DSLR was the Nikon 20-35 f2.8. That was a very expensive professional lens when it came out (but I got mine used). It never was as good with film as my 20mm f2.8 prime but still good enough that I sold the 20mm. On digital, the main problem of course was that it wasn't wide anymore but image quality just wasn't there either. The Sigma 10-20 took care of all of that. Fun lens!
