Circular Polarizer Polarizing

Circular Polarizer Polarizing
I need help. 10 points. Difference between circular polarization and the camera polarizing filter.?

I have 2 used / refurbished lens filters I to sell. I need help identification. One is a filter Quantaray. Once you are in the camera can be rotated without coming off. The original box it has been polarized, but can be a circular polarizer, as it can rotate. It is 62 mm. It has a black tint to it. How much will this sold? The second filter I have is Kenya. This is a skylight (1B) 62 mm. I need some information. I do not know anything about it. Is it a polarizing filter? A UV filter? What? It is obvious and does not rotate the camera. How much will this sold? One more thing … Do you think $ 175 is the best price for a Nikon lens? Here is a link to it.

1) All rotating polarizing filters – that's how they work. "Regular" polarizing filters were designed before the days of auto-focus, and work very well on older systems manual focus. But whatever auto-focus through the lens (Almost all) requires a "circle" polarizing filter. Adjust confused auto-focus. circular polarizers cost more than regular ones, so if the polarizer is circular, it would make a big deal of it on the package, and probably also filter ring. There is no predicting what will sell. If you are a man eBay can do a search. 2) For all practical purposes, a skylight makes no filtering. It is slightly pink, and in the old days was used to heat a photo when the lighting of the sky was too blue (hence the name). This was a problem in early slide films, but since the days of movies print photo printer color can make things what they want anyway. It is usually used to protect the front surface of the lens from damage. Not worth punishment both for resale. As I write this the link for the Nikon lens on eBay does not work, so I have no idea … Hope that helps, and happy shooting!
