OS is very helpful for preventing camera shake.
Focusing is quick.
Reasonable price for lens of this range.
缺點:
Body material may not be as durable as that of the EX lenses.
Because of the large (86 mm) lens size, it is difficult to use common lens filters. Filters of this size are expensive.
Short minimum focusing distance at 2.2 m.
評價:
This lens is not for daily snap shots, but for birds, wild lives and distant objects, and other special purposes. I am quite happy with the images taken with this lens. It is a bit heavy when hand carried, so it should be loaded on a heavy duty tripod.
