各位ching好

小妹已好幾年沒有用單鏡機了(因為DC太方便了...)，最近剛買了一部450d (以前用EOS 30的...==)，因為3月尾會去旅行，主要拍風景照，所以打算買一塊CPL，我上網搵資料時發現原來而家有專門俾DSLR用的CPL，請問同以往用的CPL有冇分別呢？因為價錢都差好遠...

請各位指教！

新舊作用無分別

你有就唔使買過(除非你$$多)

我用的是HOYA CPL, 在旺角x成買二百六 (即是被ching們圍X果間)

呢個牌子的filter唔錯, 買得過

>>>你有就唔使買過(除非你$$多)
對

明白了，即係即使我而家轉了用DSLR都仍然可以用番以前的CPL，影像都唔會有影響，咁又可以慳番了~ 謝謝各位！

用就一定用得，只係唔知新貨會唔會質素好啲

normal CPL:
* many of them do not have multilayer coating (MC) to avoid flare,
* some have just 1 or 2 layers of coating,
* some expensive one have MC on the FRONT surface of the glass but not on the BACK surface

* the rule is: cheap one have a higher chance to get flare BUT expensive one no necessary good.
* my advise: buy the most affordable one u can pay

--------------------------------------
DSLR用的CPL: (if it is surely for DSLR) should have have (MC) on BOTH side of the glass surface, they should be very expensive.

I don't have one, so cannot say anything about it.

* the rule is: if cheap one called itself "for DSLR", must be fake!

THX for yr information^^

dslr用唔到PL架..要用C-PL的.

[Louis @ Gooner]

試左先啦, 周街都有得賣, 唔得先買都未遲

Francisgamer is correct
PL for SLR is not suitable for your 450D
only CPL for DSLR can be used

if your old CPL is bought for DSLR,then no problem
if it is just a PL for SLR,then it cannot be used

btw.the best is B+W of course
can see you really love landscape,
buy 1 so you do not have to change in future

DSLR CAN still use PL in the following cases without autofocus error nor explosure error:

1. LIVEVIEW
2. focus point on nonreflecting surface such as rock, tree etc.
3. u are shooting the sky

I used a sunpak 72mm PL (bought ages ago) on Sony A100 without any error on explosure nor autofocus.

if u have old PL, don't give them up

I got a 62mm Kenko Circular PL filter from 鴨寮街 for my tele lens, cost me $248! I am wondering if the filter from 鴨寮街 is ok??

Bad news is, took some pics last week during a sunny hot day. I found a spot of flare in green color on many pics. Very strange. I am disappointed :-(

"我用的是HOYA CPL, 在旺角x成買二百六 (即是被ching們圍X果間)

我都係用 HOYA 77mm CPL, 但係 新x共 買了三百五. (俾人搵笨添 :p)

MULTI COAT 通常會貴d, 但 透光率 會好d, 色調偏差, 色度影響 會小d, 防污性 會高d.
