Filter Brand: Crystal Optics.

[Zephyrize]

Does anyone ever heard about them?
The reviews on the website look good, but so far, I only used Hoya Filters.

Crystal Optics sells a 3-kit 77mm filters (UV, PL, FLD) for only 45$...
I have some doubts;
Anyone can clear them out?

Here's the website for reference: http://www.overstock.com/Electronics/Crystal-Optics-77mm-3-Piece-Glass-Filter-Kit/2601761/product.html

Thanks!

For that price, they will suck

Do yourself a favor and save your money for some B+W filters or one of the other high end manufacturers. Nothing will degrade the quality of ANY lens faster than a cheap filter.

No mention of multicoating? A good brand (Hoya, Heliopan or B+W) single-coated 77 mm UV filter (just a single filter, not a set of 3) goes for $50, and based on experience we recommend you only consider multi-coated filters. They don't say, so it's probably a linear polarizer, which may cause problems for your AF mechanism. Circular polarizers are the recommendation there.

I too, have never heard of that brand of lens filter? B+W and Heliopan are considered very good filters...

Thanks guys for the quick response!

Well, looks like I'll just stick with Hoya.
For my other lens, I have a UV(0) from Hoya.

What about this one for my 77mm ? Is there a REAL difference of paying more 30$ for a multicoated?

Yes, there's a major difference. Check out the Protective Filter FAQ (http://photography-on-the.net/forum/showthread.php?t=368177) for more info. But, yes, it's worth it for a filter that's going to be on your lens essentially all the time.
