I've been using 3 'L'-series Canon zoom lenses to cover 16mm to 400mm and been very pleased with their performance as an amateur landscape/wildlife photographer having come to grips with their cost and weight. I recently bought an new, inexpensive 50mm/f1.8 lens off E-bay and spent a day shooting flowers at a local municipal rose garden and had an absolute blast. When I loaded my images onto the computer and had my first real chance to review them, I was very impressed. They're tack sharp, great color balance, and absolutely no vignetting in the corners. It's a perfectly usable lens in the right circumstances and I'll find a place for it in my bag.
