Very poor polarization characteristics. I regret having bought Osaka CPL and recommend people stay away from it and buy pricier but better specced CPL filters. If I seller accepts returns, I would return the product immediately. Because it has poor polarizing characteristics I will not use it. The color shading changes as one rotates the filter but polarizing effect does not show the variation it should. A waste of money.

Good for the price

Delivered wrong size filter.

Seller dont even seen the size &shipped.

Poor service.

Worthy product

Worth the price
