Very light weight in terms of its range.
The picture quality is quite good under bright light conditions, actually the quality is much better than i expected when I bought it, I thought this price won't offer me much, however I really drop my glasses.
Very cheap price in terms of the quality it offered, esp it is build in with IS.
缺點:
The design is bad, very plastic, similar to kit lens.
When zoom, the lense will go inside and out and will trap dust easily.
In dim light, it's just normal performance on the contrast and colours.
評價:
Will definitely recommend beginners to buy this lense if they have limited budget for a tele lense, which was exactly my case at that time.
Of cos if you are willing to pay more and willing to put on more weight, i think little little white 70-200 F4 is a better choice. But this lense has its competitiveness on its weight. You don't want to carry a heavy lense around whole day during a trip, 55-250 IS is a better choice.
I considered sigma and this one and I chose this one at the end because the quality of the pictures i seen with this lense seems better. It is good quality for money, you will not be disappointed.
