It is listed at $399. Add it to your cart and it should be reduced to $299!
They are also including a couple of free "extras."
That is an incredibly good price for a high quality 2.8 DX zoom. Note the "
DX"- it is APS-C only.
It comes with Sigma's 4 year extended USA warranty. The best price I have
seen before was $269 for a grey market lens on eBay.
DxO rated the Sigma 17-50 2.8 as the sharpest standard zoom on the D7100 24
MP.APS-C sensor.

发帖数: 742 | 7 说起来有点奇葩，我之前是不会是摩托车的，买车也是很随便就买了，走进车行直

梁感虫同学提供的理论知识，还有感谢各位群友的参与讨论！让我学到了许多机车理论

发帖数: 15201 | 27 来自主题: PhotoForum版 - 南加的秋天 f3.5----f5.6的大变焦头啊，你不狗谁狗
品质一流的一般是定焦头，比如35mm,50mm,85mm那些。
略差点是变焦，但是能保持恒定光圈的。比如16-35 F2.8,17-55F28,24-70 F28之类的。
再次才是变焦头，不恒定光圈，基本就是成本低，用料省，光学质量一般。 |

D800出来后， 应该会升级。 |

发帖数: 5809 | 38 希望弱光下拍摄不错。一般夜晚如disneyland有月光就能拍的头。
现在有个ASP-C
50mm 1.4能勉强做到（4mp ISO<=1600 @ 1/40-1/60s)，画质可看
还有个11-16mm f28@11mm能做到（无防抖）
如果收个D800，分辨率用9MP,能有多少改善？(换头成14-24f28) |

m43photo.blogspot.com/2012/07/sigma-30mm-f28.html
photozone测了sigma这2个头在nex上的表现, 30确实比19要好一点
12-35比19好一点, 30也比19好一点, 所以12-35和30大概差不多. |

发帖数: 532 | 48 也是我的标配。
旅行加DA15，F28 2.8。可以Cover99% 场景，大小重量正合适。 |

发帖数: 532 | 49 旅游时大多数情况18-55WR够用， 偶尔用50-200WR拍远景。
要求高的话还需要一个大光圈定焦在室内，晚上光线不好时用，比如DA35 2.4。
我的K5配18-135加F28 2.8 旅游用。 |

发帖数: 532 | 50 这几天HIKING 时手拿K01加28MM 定焦, 单手握持还可以, 比K5 轻多了. K01 画质很好
. 不知用同样底的理光GR 配28MM 镜头画质会和我的K01+F28 2.8 一样吗. 要是那样的
话真是旅行利器啊. |
