優點:
1/ IS is very powerful, the picture image is still sharp when exposure time is as short as 1/5s
2/ Light weight
3/ Can take a picture in a very short distance, as close as 0.25M. Can be used as macro lens.
4/ Less expensive, you can find it around HKD700 in second hand market.
5/ Good picture quality in light condition.
缺點:
1/ Flare resistance is poor, a lot of bright spots appear on picture when camera faced to the light source.
2/ Small aperture, picture quality drop down dramatically in dim environment.
評價:
I bought it together with my 450D. Its performance largely exceed my expectation at such a low price value. It can give a very sharp picture from corner to corner when aperture set to f/8 to f/11. In addition, when you put a close up filter on the lens, its close up function perhaps can be comparable with the professional close up lens. Its light weight is one of best advantages, put together with 450D the total weight should be less than a kilogram . After all it is a very good walk around lens,
