[閒聊] 手邊幾個鏡頭比較
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)

D7100告訴我準焦了，但是蔡頭在F2.8之前，放大到1:1時，
樹皮紋路都沒有很清晰，F2.8時突然變的超清晰。

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?)
