小弟早幾日入左支小小白non is (一手), 完左幾日都冇事(或者因冇夜晚影所以唔覺有事)

今日加左個kenko pro 1 filter, 手痕痕夜晚走去影下野, 結果發現用大光圈會有光既殘影, 如果收細光圈反而唔見有, 之後試左同一角度同一光圈快門iso 用50 .8 影就冇殘影...

返黎先醒起會唔會關個filter 事....有冇Ching 知咩事?

usually, the bad quality of filter is most observed in telephoto lens (loss of sharpness) & in ultra wide (flare)

I usually don't use filter for non expensive lenses OR buy a good filter, e.g. CANON, B+W, Nikon, Sigma original brand & avoid Kexko, Hxya, Tokinx etc because there are many many fakes one of these brands

但係我枝小小白is都係用Kenko L37 UV, 但未試過有你呢個情況出現喎！

拆左塊filter試多次咪知~~~

[calwkf]

係喎~ ching快d去試試啦~

今日太陽下用冇咩問題.....有Ching 話係大霧/有煙霞就會咁, 下次夜拍再試拆filter

好明顯係內反射造成既重影，啲白點係大廈窗口四隻角既燈。

內反射呢家野, 拆filter有無得救ga?

[JSmith]

如果起因係來自filter，當然拆filter就可以解決，或者買過塊靚嘢
如果係來自鏡頭本身，當然係冇得救，或者買過支靚嘢
如果係來自sensor，當然亦係冇得救，可以買過部靚嘢

[amadeus_hk]

sensor 都會有內反射?
如果話係來自鏡頭本身? 咁唔通係小小白non is design 問題?

[JSmith]

數碼機sensor唔同菲林，菲林唔會反射，但sensor上面就有一層層layer，表面光滑，係會反射光線。新式鏡頭後組鏡coating就會特別設計for 數碼機，可以減低呢種內反射。
