產品評論

I purchased this lens less than a month. I used it in Safari game shots. It comes in handy. The weight is appropriate for handheld shots. It is quick and responsive on my A1. I would recommend a built in 1.4x alternative for field shooting and , if possible, a camouflage color to avoid attractions and reflections while shooting through glasses. I am very satisfied with this lens overall.

全開成像都好銳利，對焦速度好快，加左1. 4完全沒有影響，加2.X後相對變慢左小小，同埋一定要用3腳架，因為震幅會變大，想手持快門要調得好快先得，同埋高光位要收細1，2格先可以無紫邊，整體來說，影暗位或動態大的一定唔可以加增距，最多只可以用1. 4，影水鳥或郁動幅度唔太大的可加2.x，另外枝鏡的手感真係好好，做到好平均，唔怕好似以前啲大鏡咁，頭重後輕， 另外分享2張相， 1張係大約2，3米左右影的，飛版係加2. X後的，都係直出版，因為買左枝鏡反來都係半個月左右，用得唔太好。

400mm/2.8係E mount鏡頭最重要嘅焦距之一，亦係運動項目攝影師最重要嘅利器，自A9面世後，一直期待這支鏡頭嘅出現！
