guys...wanna buy a CPL....got 2 choice in my mind...
Hoya Pro 1 Digital Circular Polarizing CPL and  B+W 62mm Circular Polarizer (Slim) Multi-Resistant Coated (MRC) Glass Filter.....
which one better??

Holy f**k tat series of B+W cpl.
82mm can cost u Rm700+ 
wait what ? buy buy buy 

Soony: No, step up rings and bigger filters reduce vignetting! Of course, ultra-wide angle lenses are already using 77mm and 82mm filters.

if it was me, i plan properly, because, not all lens, given shooting situation, will need CPL or ND.

so, plan properly, which lens u REALLY REALLY will NEED in the future (not buy for fun to try for fun,...) then grab a CPL that making sure that lens, will follow u, and shoot most of the photo (like walkaround lens).

and, when u attacH* CPL, you Dont use Hood, coz u need to turn the CPL< with hood, u cant turn the cpl. LOL.

*edit: *#%^@ i always type attack instead of attacH* (u see, i type attack again *#^%&@)

Got ah stepup ring 62mm to 77mm ?

Soony: No, the hood will not fit.

Do not bother buying a CPL for an ultra-wide angle lens. You will never be able to tune the CPL evenly across the frame.

lwliam: cz16-80 can't use any filter, will cause vignetting. I've got pro1d CPL filter, also will cause vignetting. Anyway, for any CZ lens best to use without any filter. Putting a filter in front of the lens will lower down the quality of the pic unless ur using cz filter as well.

at 16mm? ehm...

i'm using the cipok nicna 62mm CPL pro1d slim...i do get vignetting at 16mm but not at 17mm...

looks like only the VERY expensive filter dun get vignetting at 16mm...

if you don't plan to sell SAL16105, i would advice you not to buy the tamron 1750, trust me, f2.8 is not gonna help much in low light if you don't use flash.
if i were you, i may consider getting sigma 30mm 1.4 for the huge aperture for lowlight and bokeh shots, that will make more sense.

i think what u mean is zooming in by 1-2mm?

0168257061: Some shop I know sells loads of Carl Zeiss T* MC protector filters to Nikon and Canon users. I have Zeiss, Hoya Pro1D and B+W filters and I can tell you that the Zeiss filters are every bit just as good, minus the scratch-proof claim that the B+W and Hoya HD filters have.

Soony: The Sigma 30mm F1.4 is sharp.

when the review says bad, mostly it was compare to a better lens, hence, there Are Another Better Lens to worth over that lens. when u get seriously good review, mean, it is on it's own top class with no much to compare. looking around, i think there are few more better choices of lens to fit ur sytle.

Next time need look for the carl zeiss filters.
u know who is selling ?
hard to find eh

wasnt that the point? when i say better mean, same range, but better after the comparison.

50mm and 30mm are totally diff, from the element curves. of coz the 50mm will be sharp all over compare to a wider like 30mm or 20mm. dont matter the lens are super G or normal lens, a good lens will always get better judgements.

nikon? aisks, when they do a review of "A" lens, the review doesnt apply to a "B" lens. u have to get (dig it) for a proper full review on the siggy. (like achew loves to say, dont compare an apple to and orange, now i say, dont take apple review to judge an orange)

i dont really bother with F1.4 lens nowadays, because on my A300, (assume applies to A330 too) the AF sensor arent the best, thus i get inconsistent focus accuracy with F1.4 DoF (or sharpness). thus end up i rather shoot at F2.8 above, hence i choose a zoom F2.8 then F1.4 lens.
