- prone to collect dust inside
comment:I have bought the lens used but like new. Although I did not use it extensively, one annoying dust particle has appeared inside after a month of usage. Fortunately it does not seem to affect the image quality.

Now after a year and half or so, I have found myself to use it more as a portrait lens. The AF is surprisingly fast in this case. I have shot several landscapes as well and the sharpness is very good even when focused at infinity.

Compared to 100-200/4.5, it is sharper at 100/4.5 but seems to have a little less contrast. At F5.6, I would say, the contrast is equal, and the sharpness still a bit better.
