DxOMark於今日稍早刊出了他們對新舊兩款Nikon 80-400mm的評測。
其中新款的表現明顯優於舊款,當然價格也是有顯著的差距。
究竟這支相隔13年的後繼者有多麼強大?請參考以下譯文:

光學表現:

Optically the Nikon AF-S Nikkor 80-400 f4.5-5.6G ED VR is completely different from the previous model,
20 elements including 5 of ED (Extra-Low Dispersion) or Super ED Glass arranged in 12 groups (formerly the lens had 17 elements in 11 groups, with 3 of ED glass). The DxO Mark score of 22 makes this the best super-zoom yet tested: 4 points above its predecessor. The individual parts of the score are good for the new lens
too: sharpness at 14P-MPix is just one point behind the
Sigma 120-400 f4.5-5.6 DG APO OS HSM Nikon but
the Nikkor scores better overall and much better for chromatic aberration.


首先這支新鏡在光學設計上就完全不同,20枚12群的鏡片組中包含了5片ED鏡片及Super-ED鏡片。
(舊款為17枚11群,3ED鏡片)。
在DxOMark測試中得到了22分,使他成為有史以來表現最好的高倍率變焦鏡。比他的前任還高了4分。
而在各別項目中,新鏡的表現也相當優良:
銳利度為14P-MPix ,只比Sigma 120-400 f4.5-5.6 DG APO OS HSM 低了一分,
而且Nikon新鏡的整體表現較佳且變形控制更是好上許多。

There are other areas where the new Nikkor is better than the old, it utilises Nikon’s Nano-Coat Technology
for reducing flare and even more crucially the AF on the new lens is driven by a SWM drive which is pretty
quick, on the old lens AF was driven from the body, meaning that AF was not possible using some cheaper
Nikon cameras. On the down side it is heavier and bigger, but it is a 400mm lens and the extra weight seems to be justified by the extra quality.

其他的項目新鏡也比舊鏡表現較好,他利用了奈米鍍膜技術來降低耀光,更重要的是新鏡是由SWM來對焦,
因此相當的快速,而舊鏡則是由機身來驅動,代表著無法接上較便宜的Nikon機身來使用。
另一個缺點就是更大且更重,但他是支400mm鏡頭,而且多出來的重量似乎也換來了更好的成像品質。

結論:
So, is the new lens worth it? Yes, it is, this is a good lens. If you want to zoom from a short Tele right up to
400mm this is the best choice you have. However, before you spend your money do look at the quality
implications of getting a
Nikkor AF-S 70-200 f4G ED VR and a longer prime lens, maybe a 300mm f4.
The 70-200 has a DxO Mark score of 28 and sharpness of 21P-MPix, it and a 300mm f4 would still cost less than the 80-400 and might give you better results.


所以這顆新鏡頭值得他的價錢嗎?是的,他值得,這是一顆好鏡頭。
如果你想從短望遠直接變焦到400mm,這是最好的選擇。
然而,在你花大錢之前,不妨先看一下Nikkor AF-S 70-200 f4G ED VR和長焦定焦鏡的這個組合,
也許300mm f4吧。70-200在DxOMark得分為28且銳利度為21P-MPix,
他和300 f4加起來還是比新款的80-400便宜,而且可能成像品質更佳。
