Very expensive lah. The marumi 62mm cpl rm240. Can die liao.

thickness is only part of the so called "quality" factor. what about the light transmissivity (ability of the glass to allow as much light to pass through as possible)? how about tint? does the glass have any undesirable tint? inferior glass is known to have bad tinting. another important factor is flare suppressing. good filters have good coating on top of the glass to minimize flaring which affects the image badly. another point to consider is the ease of cleaning. certain manufacturers includes a top coating layer to makes the filter easier to clean once it gets smudged with grease or oil (which it eventually will). you will be surprised to know that the original Hoya Pro1D (which this guy says has the same "quality") actually is one of the most difficult and annoying to wipe clean amongst all the top brands. I know because I had used it before.

are these important for cpl?

If i'm using cpl my uv will still be on ma. cleaning i agree.
But amt of light passing through is for uv only? No?

Ya...I m using a33, it work well for me, damn like it. I feel regret after few days why don't I buy canon n nikon instead of sony, bt nw I m fully satisfied wif my a33. Some more two lens in a price.
Buying 2k for a old technology rather ,spend 2k for sony to get a newer technology...although it not perfect but still consider very good d...haha

Eh..i notice something when using 50mm..i used local AF and focus on face, when it come out not well focused..how come??..(>.<)..i use MF is much sharper, but it could be slower..it is expected??

Brought A33 today. I wonder how long the battery need to charge for first time and how long after that? Do you guys have sony warranty in the box? I don't see mine, just have warranty registration card.

My winning shot from alphanatics January competition!

8 hour, no warranty card la....

congratulation!
so does that means u get another f42 flash?

Erm no... If you put cpl with your UV on, light transmission will be lowered as light has to travel through your CPL as well as your UV, to achieve the best results, you'll need to swap your cpl with your UV when you want to use your CPL.

so i have to online register? hmm

8 hours? how abt next charge?

not really true here, UV has minimal light lost, but CPL, is 2 or 3 stop light lost..
people swap UV and CPL is to avoid the vignetting
@newbieeeee
and CPL is not always-on filter, use when it need only, so, for me i think i'm a GWC, i wouldn't invest into an expensive stuff i don't really use often.. ordinary rm40~50 CPL filter works for me already
