Adam Tow of COBA posted a good list of Canon lenses and notes Patrick Murphy’s comprehensive list and database.
for my nikon, i have a 50mm/f1.8, a 17-70/f4.5-5.5 and a sigma 70-300/f4-5.6. since i do a lot of concerts, what i really want is a 20-100/f 1.4. but i can’t imagine such a thing existing (or costing less than my camera). for compairson purposes, note the 28mm/f1.4 is $1700; the 35mm/f2 is only $300.
