请问GoGoGo:
just bought a Tamron 17-50 (A16, non VC version). after couple days of use, i found this lens has a back focus issue. (tested my other lenses on my A33, and they are fine. so the issue is the lens no the camera). My issue is pretty much similar to this: http://www.dcresource.com/forums/sho...50mm-SAL50-F14 Is that a big deal? Does your A16 have any front/back focus issue? Thanks in advance! |

我个人感觉啊: A33/A55的软件可能有自动纠正偏焦的功能, 你多拍一些, 看看两百张之后是不是就准了 |

我的A16貌似没有"腾龙黄"啊 这里的前三张就是我的A55机身+A16镜头: http://www.chinasmile.net/forums/sho...d.php?t=517339 我是直出JPG, 自动白平衡, 一般色彩都挺自然, 并不需要后期再校正白平衡 |

前段时间凑热闹也收了一只腾龙A016,刚刚卖掉了。 A016的锐度确实很好,全焦段2.8可用,F4就纤毫毕现了。据前用户说他拿去腾龙调了一次焦,可见部分产品是会跑焦的,个体差异是存在的。 腾龙的色彩不讨喜,这是我不喜欢的主要原因。户外自然光,A016的白平衡还算马马虎虎,但是和原厂镜以及我手头的几个Sigma头比起来欠油润;室内混合光或者弱光场景,A016的白平衡就死得很难看。即使前期拿白平衡盖矫正后拍摄,依然不是很理想,更不用说后期软件的矫正了。 另外,A016的广角畸变控制也比较一般。 不过,就A016的价格来说,是非常超值的,稍有改善的其它品牌都要超过50%以上的投资,更何况,锐度还不见得能与之匹敌。 |
