Need a new circular polarizer filter is there specific features to look for or avoid? Better brand than another?
There are a lot of good brands. Some things to consider:
- Is there a color cast. Most good brands don't have a color cast.
- If you shoot wide angle, will it vignette. Some polarizers are thinner than others. If you shoot really wide, you may want to get a larger filter size.
- Will you be swapping between different lenses with possibly different filter sizes. You could get separate filters, buy the largest that you need and use step up rings, or consider a magnetic system for easy swaps.
- Are you going to combine the polarizer with other filters (e.g., a neutral density filter). If so, you will probably want to get a magnetic system for ease of use.
- Are you going to add graduated neutral density filters. If so, there are several systems that allow you to do that.
