Replaced this with the Canon EF 28-135 due to softness all over and a general lack of contrast. The colors from this lens always looked washed out.reviewed January 5th, 2007
The close focusing distance was nice. This lens is nearly capable of macro work (albeit with a low magnification ratio)
One advantage is it is very light weight.
