>>我加咗個 Kenko L37 UV ，但喺影出黎D相好似唔加仲好 D
Yes, of course. Any glass put before your lens will degrade the quality of your pic to a certain extend.........depending on the quality of the glass you use

I use Kenko UV on my G2 but nothing really noticable on my pic so better check with the shop that the UV is a good one................

>>硬喺好似瘀瘀地咁
You mean the color or what.............can't understand what you mean............
If the UV even change the real color of your pic, exchange it immediately.......

>>又唔夠 Sharp wor
An UV will not have such a bad effect on your DC............may be something else is not working properly in your CP5700............may be it's time to use your warranty..........

I am using Kenko Super Multi-Coat UV, which costed me $150, i think it is better than 1B la. It claimed that 99.7% of light can pass through !
>>硬喺好似瘀瘀地咁 : i mean the colour of the picture.
>>又唔夠 Sharp wor : You are right, normally the UV filter should not have such effect, may be my 5700 has problem.
Anyway, i will try NOT to use that filter and then take some photos to compare again, if probem persist, i will ask Nikon HK.

Thanks DC&ME.

我不嬲都唔建議用UV做PROTECTOR, 尢其係DC的SENSOR根本唔會受UV影響, 但加了UV之後應該唔會顏色變瘀, 照計KENKO質素都唔會太差, 你試下加了UV之後PRESET WB試試有冇改善, 若效果不滿意的話, 放棄好了。

我自己就經常加塊HOYA SMC 1B做保護鏡, 1B本身有少少紅色, AUTO WB得出既效果輕微偏暖算幾悅目, 但用MANUAL WB時仍然可以得出準確色調。

我都係用 Kenko L37 UV 喎 + CP5700
但係無你講o個D問題！

[KennyLau]

Thanks Oldpear and Digcam, i will try to use WB Preset to see the effect.

I am still wondering why my 5700 has such problem, shall i not to use the UV is better in a not shiny day ? In another words, under what situation/condition shall i use/not to use the UV ?

[digcam]

我當塊Kenko UV 鏡做保護鏡，24小時都用。
我諗應該唔關塊UV鏡事，可能D setting 有問題。
你試下 Post 你D setting 出黎，睇下手有無咁既問題？
thanks

[KennyLau]

你D相無乜問題呀！係唔係影果日天陰呀？
唔知同大光圈有無關係？

[dianelo]

唔覺有問題喎, 好多時天陰我影出o黎d相都係o甘
我都係用5700+ hoya uv

[KennyLau]

哦，咁樣．．．
好，等我下次再試吓加 filter 同唔加 filter 黎影先．唔該咁多位嘅幫忙 :-)

I think that the problem of first pictures may because of the low shutter speed since it is only 1/112 with a focal length 71mm.

For the second one, I did not found any problem in color.

[KennyLau]

I understand that long zoom willl magnified hand-shake, so i am very careful to take photo at long zoom. May be you are right, i will try to use tripod to take long zoom photos to check it out.
Thanks patkwok :-)
