when buying lens, will you bring your own DSLR body to test the lens? pls share.

我試過無帶相機去，買了之後非常不滿，兩日後蝕了一千元賣出，因此我以後都帶相機去買鏡頭。至於你會怎樣你自已決定。

bkfchung,
Thanks for your sharing. As I'm a new hand, I don't have much experience on that. By the way, if I bring my own camera body, what I suppose to test? focusing or the lens quality? some posts in this forum said that we need to look for any dust and scratches. So what exactly we are testing lens with the camera?
thanks for sharing.

michine,

我都係新手。檢查鏡頭方法都係從Nikon交流區各師兄提供的資料copy。希望幫到你

檢查鏡頭方法:
1, 看接環上有沒有磨痕(有的話代表有裝過)

2, 檢查光圈, G鏡因為沒有光圈環, 所以要用手壓鏡尾的光圈連動桿, 壓下時光圈應該會跟著打開, 試試順不順暢.

3, 跟住壓著光圈連動桿把光圈全開, 由鏡頭向鏡尾對光看 (用電筒照都得, 不過唔係間間鋪都俾咁做), 仔細檢查一層一層的鏡片是否有瑕疵, 有少量灰塵是正常的 (太多不行).
若是鏡片有油漬(霧霧的)或氣泡, 有內部的油漆剝落(會看到一塊大東西), 發
霉(新鏡頭是不容易有)就不要支鏡啦.

4, 檢查鏡頭與鏡尾的這兩片鏡片, 沿著光照一圈看是否有鍍膜瑕疵或刮
傷, 若果唔肯定係水漬或鍍膜瑕疵時, 請店員幫手擦掉, 若擦的掉就是水漬沒關係, 若擦不掉就是瑕疵, 千萬不要自己落手擦

5, 檢查電子功能啦, 接上機身後開P mode應該光圈快門讀值都有 (若是F--就是有問題了), 切到A mode 收小光圈值後壓景深預覽鈕, 從鏡頭看進去應該會看到光圈收縮, 試試開最大光圈同收到最小光圈, 以觀察其收縮的程度是否有差別.

6, 測試自動對焦,就試兩三次看會不會動就好了.

7, 測試VR, 這部分比較困難, VR因為完全沒有指示燈號, 只能夠憑感覺.
著左VR再半按快門後半秒應該會啟動, 此時若聽覺敏銳的話會聽到鏡頭有輕微的吱吱聲 (VR在動的聲音, 你可以先把AF切到M防止AF-S的聲音干擾), 放開快門製後很快會聽到鏡頭有一聲 "喀" 的VR關閉聲音(景觀窗有時也會感覺跳一下), 這樣就是VR功能有啟動.

最後, 把VR跟AF-S都開啟, 用不同的光圈值拍兩張, 若沒問題就可以上路了

thanks Perry.
happy shooting.

Thanks a lot for your info.

通常賣行貨如雙成/dcfever等地方都有機俾你試鏡的...
