What I like most about it is the aperture ratio and FR 17. The ultrasonic motor is still on my drum, like the name of the manufacturer. I am satisfied, but I don’t really understand yet why Canon is more expensive than Sigma and Tamrons. Probably, understanding will come with experience of use. The fact is that all this month I have been using the lens in the sunny south - so aperture was rarely needed.
