A killing 22

Amazon exceptional offer that allowed me to get the stone in 1300 instead of 2000, I still can not believe! :)
I currently use on an EOS 550D and clearly decreases the box rendering pictures that are so far unique in every respect.
The optical quality is to RDV, normal for a objo to 2000 you might say.
For the IS which is not present, I have currently had no complaints.
The sharpness is very good at full aperture and outstanding from f / 5.6.
The USM motor is very quiet, AF patina only in very exceptional cases.
The lock is very convenient for long walks headlong because it tends to quickly deploy.

Incidentally, if you have a doubler you keep the AF!
In short this goal delight your landscapes, portraits ... he's constantly on my case!
