B+W Circular Polarizer
Polarizers look similar to neutral density filters, and they will typically block a few stops of light, but they're fundamentally different: a polarizing filter rotates in its mount to selectively block glare and reflection, which gives you a great deal of control over image contrast and tone, while a neutral density filter evenly reduces exposure without affecting the image balance. Fun fact: a polarizing filter is one of the very few optical filters whose effect can't be replicated digitally. Circular polarizers will work on autofocus and manual focus cameras.
These B+W circular polarizers are high quality, German-made filters with excellent glass and solid all-metal construction. Choose a size from the drop-down menu below.
