因為今天比較優閒(? 上週跟朋友借的蔡頭也一直沒空測試 想說今天趁著天氣還OK 就帶出去拍測試照片了 這次主要是測試每個鏡頭在F4.0以上的光圈值所拍出來的照片 機身:NIKON D7100，A模式 ISO:100 點測光，對焦點及測光點皆為照片正中央 1號鏡頭:蔡司 50F1.4，"只能"手動鏡，http://i.imgur.com/Golty6e.jpg 2號鏡頭:NIKON 17-55F2.8，35端，http://i.imgur.com/7BT3qCw.jpg 3號鏡頭:NIKON 17-55F2.8，50端 4號鏡頭:NIKON 35F1.8G，http://i.imgur.com/StUPkoQ.jpg 5號鏡頭:NIKON 50F1.8D，http://i.imgur.com/e1zyfAY.jpg (蔡司的光圈只有F1.4，F2，F2.8，F4.0這幾個數值) ---------------------------------------------------- 地點:大安森林公園的某個椅子上 時間:上午約10點 與樹的距離:約3公尺 F1.4 1.http://www.flickr.com/photos/59429903@N03/9534628663/lightbox/ F1.8

5.http://www.flickr.com/photos/59429903@N03/9534565743/ 小結: NIKON的35F1.8G有很明顯的色散問題，要一直縮光圈到F2.8之後， 頭部色散的問題才有改善。除了蔡司之外，其餘的鏡頭即使縮光圈到 F4.0，雕像的身體部分依然還是有色散問題存在。 ----------------------------------------------------------- flickr裡面還有紅色的腳踏車與遠方的檳榔樹兩組測試照片 但是因為有點懶得打了 有興趣的人可以點進去看 http://www.flickr.com/photos/59429903@N03/sets/72157635123129684/ ----------------------------------------------------------- 結論: 單就散景部分來講 其實NIKON50F1.8D以及NIKON35F1.8G沒有輸給蔡頭诶 http://i.imgur.com/UoLVc5o.jpg 手上這幾顆NIKON的鏡頭都有不小的色散問題 即使是17-55 可能要N鏡才有辦法改善 扣除空間問題 定焦鏡的CP值真的超高 http://i.imgur.com/M2yy9QW.jpg 右邊是3000元的50F1.8D在F2.8時的照片 左邊是二手價26000元的17-55在F2.8的照片 其實看起來根本沒差多少...... 關於D7100的摩爾紋部分 http://www.flickr.com/photos/59429903@N03/9534596089/ 兩週前買了D7100之後 拍到現在快2千張 其實看不太到 因此我個人覺得可以忽略這個問題 (還是說跟手氣有關?) --
