Barn Swallow 家燕 再接再厲追飛燕

251 Barn Swallow 家燕
Fanling 粉嶺  
19/6/2004  
D100 + Sigma 120-300mm + 2x
 
(12/6-26/6 的追飛燕完整篇在這裡: http://nature.kl.edu.tw/showthread.php?s=&threadid=12579)
 
明知 F80 的對焦系統慢, 而且遇上不定的目標會十分容易迷焦, 但我都決定接受這挑戰!
 
之後一個星期, 曾翻看說明書, 加上自己對 D100 的經驗, 都沒有一個確實的方案....... 但我最後終於想到, 利用 AF-C 由近至遠的對焦特性! 先估計飛燕會飛過的地方, 再對焦在近一點的位置. 當有燕子飛過的時候便立即瞄準 (把鏡頭指向目標), 再半按快門對焦, 感覺合焦便立即把快門按下去! 雖然機會只有一次 (面對飛燕的速度, 一秒三格的連拍是沒有用的. 我要對焦快又準而且一秒八格的 D2H!!! ), 但總比一張都拍不到好的啦.
 
追到了! 可是對焦不夠準. (crop)

 
整天最佳的一張! 雖然把燕子和濺起的水花都拍下, 但是快門只有 1/500s, 拍不出清晰的翅膀.

For since the creation of the world God's invisible qualities--his eternal power and divine nature--have been clearly seen, being understood from what has been made, so that men are without excuse.

又過了一個星期, 再走同一路線. 但這天自己的狀態不及上一次, 可能是酷熱天氣加睡眠不足的關係吧..... 我不能被太陽曬太久的, 很容易會頭痛加眼花........
 
今天的飛燕都好像在避開我. 當我架好器材就不飛來.
 
但感謝神! 當我快要收拾器材回程之前, 牠飛來了! 而且不是一下子就走, 是來回飛了兩三圈才走. 終於被我拍下這一瞬! (crop)

雖然想繼續看黑翅長腳鷸, 彩鷸 (26/6 看到公鳥帶同三隻幼鳥出來覓食 ) 和家燕的成長狀況, 但是明天不是有雨, 便是酷熱. 並且多雲的天氣不適合追拍飛行快速的燕子, 看來明天都會是休息的了.
 
先在米埔「脫水」 (在觀鳥"蒸籠"內不斷流汗), 再到粉嶺「生曬」(背後的陽光無遮無掩的, 熱烈地照在身上), 這完全不是好受的.
