那些打鳥的大砲, 普遍都是F4.0起跳的...
如果200mm F5.6不夠用的話, 拍鳥焦距通常在300mm以上,
而且鳥會在樹林裡的暗處, 那些F4.0不知怎麼應付毫無預警的鳥動作
因為沒拍過這種類型的照片, 缺少經驗 敬請賜教  |
好機身高ISO催快門。。。好鏡在曝光不足時，能保留的也比較多，所以也可以曝光不足來補速度。高速連拍，容易捕捉快門不需那快的畫面。還有每個鏡頭的F4.0效果也不盡一樣。本人蹲野柳的經驗是，通常這些大砲，在和我機身同ISO, 光圈F/5.6時，機身給的快門也比較快些, 這和焦距測光或鏡片的傳透性相關吧。每項累加的下場是，你1/250s按一堆廢圖，那些砲可以1/800-1/1000說它在試飛行版。
