AF VR ED 80-400mm f/4.5-5.6D搭配原廠加倍鏡皆無法自動但可測光(須稍事修改)，
可選副廠的PRO 300 1.4x鏡來搭配，可支援自動對焦、測光及VR，畫質上也不會損失太多。

榮泰有修水貨，只是不接受水貨商品之"保固期"且沒有打折優惠，
價格以實際維修內容收費，不會加收所謂的"檢測費"。

原廠加倍鏡前端是凸出來的小心撞屁股...

修改處是原廠加倍鏡的部份
需要磨掉一節插刀
基本上80-400強烈不建議用加倍鏡
RRO300是KENKO出的
原廠沒有可以用的,就連原廠的AF-S鏡也不是每隻都可以用原廠加倍鏡的
一般再保固期內很難壞,過了保固期都一樣沒折扣,保固期還要看損壞的地方像VR機構好像不在免費維修的項目理
D70用這隻..拍客機或大型不怕人的水鳥還可以啦不然用手轉還比AF快

用來拍飛機及水鳥

Go for 300mm af-s

This is much faster and sharper. I had 80-400 and sold it for 300mm AF-S



This guy hand held this lens at 1/40s. I have same experience. But don't expect to get consistent result at this shutter speed.

Besides you need high shutter speed for sports. So VR won't help much anyway. But the AF-S is a blessing.

Remember both of them have issues with tripod mount. If you want to use it at very low shutter speeds (say below 1/50) you may have to think about Kirk collar.

Good luck.

榮泰公司貨於保固期內,非人為損壞或是無法判斷為人為損壞是不收費的,
但需注意有些部份是不提供保固的,而過保的公司貨維修可憑保單打九折,
水貨則是一律依牌價收費,個人覺得以代理商而言,
榮泰的服務態度算是相當優秀的。

ps:用手機上網打字真累....

Ai AF-S VR Nikkor ED 300mm F4D（IF）即將出現，搭配 TC-14E II 將是完美的組合。
================================================================================

哇！ AFS 300/4 真的 要 VR 了！ 400/2.8 500/4 600/4 都還沒有出現 VR 版，這麼快輪到 300/4 了！ 不過 Nikon 真的不準備出 400/5.6 啦？

PS.希望搭配 TC-14EII 不會再發生 AF 失靈的問題 :)

放眼望去,除了EF 100-400mm F4.5-5.6L IS USM,其他原廠及副廠鏡頭都沒有出超音波馬達,
我用80-400用到"X"翻了
