will a quality UV filter cut any light? Anonymous
i'm looking to get a 77mm filter for my new lens and i was wondering if a clear, good quality glass UV filter would affect exposure at all?

>> B+W 77mm UV Haze 010 (MRC) Multi-Resistant Coating F-Pro Glass Filter

is the one i want

is it so negligible that the meter won't even see a difference?

It's always negligible, even cheap quantarays will do, you dont need to spend big bucks on a UV filter, even 10 dollar ones will do.

Even if it isn't multicoated, ghosting will seldom occur, and if it does, it's often because you're being stupid.

The real issue is vignetting caused by the filter's edges getting in the way of the visible field. B+W is clear as a bell, but the physical dimensions may cause light falloff on the edges of your photos.

what's the difference between these

>> B+W 77mm UV Haze 010 Glass Filter
$49.95
>> B+W 77mm UV Haze 010 (MRC) Multi-Resistant Coating F-Pro Glass Filter
$93.95
>> B+W 77mm #007 Protection Clear MRC (Multi-Coated) Glass Filter
$89.95

so i guess one is UV haze only, one is multi coated only and the most expensive one is UV haze AND multi coated

what are the numbers for? 007 and 010?

AFAIK UV and protection is same thing when put on dSLR camera. Film had some issues with UV light. B+W MRC is as far as I know the best filter, it has coating that's resistant to scratching, they claim it's more resistant than glass.

BTW, when you buy a 1500 USD lens, I think that it's bad idea to degrade it's quality just to save few bucks on filter. I use B+W, standard, not MRC, and it works very well. If you use wide angle lens, than slim version is a good choice, to prevent light-falloff. However, on my 10-22 I don't see any vignetting, unless I stack UV+CPL.

>> B+W 77mm UV Haze 010 Glass Filter
An UV filter with simple coating

>> B+W 77mm UV Haze 010 (MRC) Multi-Resistant Coating F-Pro Glass Filter
An UV filter with better coating which may or may not improve quality compared to the previous one

>> B+W 77mm #007 Protection Clear MRC (Multi-Coated) Glass Filter
Same as the above, but doesn't block ultraviolet light; though you won't see any difference with a DSLR which has an UV-blocking filter inside anyway

>what are the numbers for? 007 and 010?
B+W's codes for each filter type.

Also, these prices are outrageous. I bought my 72mm B+W 010 MRC for 30 bucks.

There are a lot of fake B+W filters around too. Be careful. If it is too good to be true then don't fall for it.

No such thing as a "quality" UV filter.

thanks for info, dude

dunno, those are the prices on B&H. maybe 77mm is exponentially more expensive?

1) Yes, the cost increases exponentially. I raged at the prices of polarizers when I switched from 58mm-thread kit lenses to 72mm pro ones.
2) B&H isn't exactly cheap when it comes to filters. I got mine through a shady local dealer, but it seems to be authentic.

buying a lens at the same time with them so i'll order the filter with them at the same time :/
