seems like the capability is awesome. I personally like the compact size, hsm and weight.
i agree with the conclusion
End evaluation of this Sigma 24-70F2.8HSM lens, positioning it so that I can not help but the characteristics of association to the last evaluation before 50mmF1.4EX DG HSM Lens Sigma. 在适马镜头里，这两支镜头是少有的高画质高配置加高价格镜头。 At Sigma lens, the two lenses are rare high-definition heightening Price high to configure the camera. 相信这两支镜头的出现绝非偶然，在现在这个竞争激烈的商业社会里，产品精品化高价化、品牌高端化是很多企业品牌的终极目标。 I believe these two lenses do not emerge accidentally, at the current highly competitive commercial society, products of high quality and high-end brands are a lot of corporate brand of the ultimate goal. 因此，它们的出现让我们感觉到适马似乎正在调整自己的品牌定位，它们在告诉我们，适马希望摆脱“副”厂廉价路线，而在尝试走高品质高价格路线了。 As such, they let us feel the emergence of Sigma seems to adjust its own brand positioning, they told us that the Sigma is to escape this "vice" factory cheap route, and in trying to move up the quality of the high prices of the route. 如果真是这样，我们相信，在此之后，适马还会陆续推出类似定位的镜头。 If so, we believe, after which Sigma also launched a similar positioning of the lens. 也许，下一个就是16-35mm这类经典镜头。 May be, the next is such a classic 16-35mm lens. 对于消费者来说，付出比原厂镜头稍少的价钱，就能买到素质和原厂不相上下的产品，这，或许并不是个坏事情！ For the consumers, they pay slightly less than the original price of the lens, you can buy the same quality and original products, which, perhaps not a bad thing!
