I own this lens. It is a very sharp, compact, and well-built. It is excellent for low-light photography on CMOS-sized sensor cameras, like the Canon EOS 20D, EOS 30D, Canon EOS Rebel XTi, and others. It is sharp from edge to edge and perfect for low-light situations at all apertures.
I own this lens. It is one of my favorite lenses to use on Canon DSRLs, especially on CMOS-sized sensor cameras, like the Canon EOS 20D, EOS 30D, Canon EOS Rebel XTi, and others. It also performs well on the Canon EOS 5D DSLR and EOS 1Ds Mark II, but there is more distortion due to the full frame sensor.
