Hi Go.Fish,
We'd be happy to answer those questions for you. Circular polarizers are different from linear polarizers in that they can be rotated to increase or decrease the intensity of the polarization effect. Linear polarizers do not have this capability. Most of the polarizers we sell are of the circular variety, including the ND-PL hybrids present in some other sets.
The filters should not hinder the camera's ability to focus. If mounted properly the camera should ignore their presence for the purposes of focusing any shot. If you believe there is a focus issue of some kind that is only present with the filters, please reach out to support@polarpro.com and we'll be happy to help out.
The differently-colored bezels on the filters are there to denote which series the filter is a part of. The black filters are the Professional Series, while the bronze are the Cinema Series. The difference between the two series is the quality of the glass used. Cinema Series glass is of a higher quality than the glass in any other filters we make, and is coated multiple times for a boost in glare and lens flare resistance. These tend to be popular with professionals, and folks who just want the best possible image quality when shooting.
The filters will not produce any grain in the images. Grain is a digital artifact that is normally produced by camera sensors in low-light situations, or if the ISO is boosted past about 400. If you're seeing grain, we'd recommend taking a look at the camera settings to see what it's shooting with, especially so if you're shooting in auto.
Hopefully this information helps, but if you have any other questions please reach out to the email above and we'll be happy to continue helping out.
