I have tried a lot of legacy primes and some modern zooms. This lens tops them all except the Canon fd 100th f2. But is so useful. I use it for macro and even at 1:3 it is excellent. The colors are gorgeous and it is sharp at every focus and every aperture. I never believed a zoom could be this good and the lack of auto focus is more than made up in the image quality. A top canon lens for all time.
