因为今天比较优闲(? 上周跟朋友借的蔡头也一直没空测试 想说今天趁着天气还OK 就带出去拍测试照片了 这次主要是测试每个镜头在F4.0以上的光圈值所拍出来的照片 机身:NIKON D7100，A模式 ISO:100 点测光，对焦点及测光点皆为照片正中央 1号镜头:蔡司 50F1.4，"只能"手动镜，http://i.imgur.com/Golty6e.jpg 2号镜头:NIKON 17-55F2.8，35端，http://i.imgur.com/7BT3qCw.jpg 3号镜头:NIKON 17-55F2.8，50端 4号镜头:NIKON 35F1.8G，http://i.imgur.com/StUPkoQ.jpg 5号镜头:NIKON 50F1.8D，http://i.imgur.com/e1zyfAY.jpg

5.http://www.flickr.com/photos/59429903@N03/9534565743/ 小结: NIKON的35F1.8G有很明显的色散问题，要一直缩光圈到F2.8之後， 头部色散的问题才有改善。除了蔡司之外，其余的镜头即使缩光圈到 F4.0，雕像的身体部分依然还是有色散问题存在。 ----------------------------------------------------------- flickr里面还有红色的脚踏车与远方的槟榔树两组测试照片 但是因为有点懒得打了 有兴趣的人可以点进去看 http://www.flickr.com/photos/59429903@N03/sets/72157635123129684/ ----------------------------------------------------------- 结论: 单就散景部分来讲 其实NIKON50F1.8D以及NIKON35F1.8G没有输给蔡头诶 http://i.imgur.com/UoLVc5o.jpg 手上这几颗NIKON的镜头都有不小的色散问题 即使是17-55 可能要N镜才有办法改善 扣除空间问题 定焦镜的CP值真的超高 http://i.imgur.com/M2yy9QW.jpg 右边是3000元的50F1.8D在F2.8时的照片 左边是二手价26000元的17-55在F2.8的照片 其实看起来根本没差多少...... 关於D7100的摩尔纹部分 http://www.flickr.com/photos/59429903@N03/9534596089/ 两周前买了D7100之後 拍到现在快2千张 其实看不太到 因此我个人觉得可以忽略这个问题 (还是说跟手气有关?) --
