hmmm...
what's wrong with a Hoya UV?
we are just talking about a UV filter here aren't we?
i doubt anyone can see any difference between a picture taken using a B&W UV to one taken with a Hoya UV. otherwise, it is simply forking out more $$ in exchange for perhaps, a greater 'peace of mind'?
and pictures taken with HMC or non-HMC, really, who can tell the difference?
if u can afford the better goods in life, in this case a B&W or Nikon UV filter, and believe that they will improve ur photos more so than a normal UV filter, then go ahead and buy them. :thumbsup:

that's not the purpose of polarizers, to make pictures darker, no. and it is way too expensive and incomprehsible to be used as a 'protection' for ur even more expensive lens.
although it does add 2 stops and generally renders the whole picture to be a little darker...
polarizers are meant to be used to remove reflections caused by the sunlight that might not give the photographer a 'perfect' picture.
of course there are other uses for polarizers, i.e. getting a 'true-blue' sky, enhancing the colour balance and to take away unwanted stray reflections and etc.etc.
for more information on the use of filters, do find books to read up on.
The Photographers' Guide to Filters by Lee Frost is an excellent book and can be found in the National Library at Stamford Road.

Max, then u must offer advise objectively. If it is your personal preference, let it stand. However, a newbie asking this question might not like their pics to be dark.
And may I ask how you shoot in low light? Do you take out the polariser? And if you do, what, may I ask, protects your lens then?
Sounds moot dosen't it? :think:
Madmax said:
You wanted your pictures to look darker, you can always dial a stop under to achieve that. Why need that circular polarizer filter?
Really have doubt coz I never heard of ppl using a circular polarizer to have his/her pics slightly darker?! :think:
Any other you guys heard of that too? :what:

I think what he meant by "darker" means more saturated.
A polariser is a specialised filter and only works in certain situations. It should not be kept on the lens all the while for the reasons that have been mentioned. If you're on a budget, get a Hoya uv filter. If you have more to spend get their HMC or SHMC filters if you're using wide angle lenses.

Nobody asked you to shut up. Com'on we're all learning, CPL is used when you need saturated colours, Nikon DSLRs automatically avoids blown highlights (as others like to call it underexposure) there's really no need to affix on a CPL on all the time.Madmax said:
Imagine a 12-24DX 24-120VR, 70-200VR, you'll need 2 x 77 mm CPL, 1 x 72mm CPL. The cost is... :bigeyes: Just comment on the more common usages lah
normal UVs will do.Your lenses are up the K's, don't scrimp. Justify the protection & images with a B+W MRC anytime, anyday.Kit said:

Me? Soon be free leow...concuss said:hehe, yeah watcher, I guess we all guessed that by now! And might I add, I use hoya!! haha... no money
Hey, when u free? Wanna go bird shooting?
Weekend for now... Just finish shoots the past two days. Met (a very exhausted) Willy Foo too 
. Buzz me...I have been wanting to ask this question all along. As we know, films are sensitive to UV (the blue layer) and aren't that sensitive to IR. However, for sensors, they are sensitive to IR (which already has been taken care of by default) and not so sensitive to UV, if any at all.
So why buy UV? Can we buy a neutral filter but very high quality multicoated one? I apologise as i do not know much of the stuff out there in the market, so would be greatly if someone could steer me towards it.

why buy UV?
it is the cheapest and considered to be the most 'neutral' filters around(does not give u any additional stop like a neutral density filter and it renders colors that are more or less the same as u see them), that is afterall, a piece of normal glass. it is coated to defract/deflect or limit the amount of light-rays(or stray light-rays) into the lens and onto the film or sensor itself, thus, in the process, minimising flare, ghosting etc. etc.
anyway, most users jus chuck a UV filter into their front of their lens merely as a means of lens protection. i do that too. jus a normal UV filter. they are all the same to me.
HMC UV filters are mainly UV filters that are given that extra coat. but whether it does its part as opposed to a normal UV filter is highly opened to debate.
what can a multi coated 'neutral' glass do? what kind of coating? UV coating? or...?
i'm not sure if there's a 'neutral' filter around that is not UV, not Skylight or any other of that nature.
but i got a feeling u're referring to a normal glass piece with some form of coating on it. but, what type of coating then?
correct me if i'm wrong!

Nikon does make NC (neutral colour) filters. Think they've been pushing it over their UV filters cos film nowadays are not so senstive to UV, and with digital, UV protection is a moot point.
