Circular polarizing filter (CPL)
A rotating filter that screws onto your camera lens to cut glare and reflections from glass, water, and shiny surfaces while deepening sky blues. Essential for shooting through windows or capturing architecture where reflections hide details.
What to look for
- 1Match the thread size to your lens diameter (check lens barrel for number like 52mm, 58mm, 67mm, 77mm)
- 2Multi-coating to reduce internal reflections and maintain sharpness
- 3Slim profile frame if using wide-angle lenses (thick frames cause edge darkening)
- 4Rotating outer ring that turns smoothly without too much resistance
Skip
- Filters marketed as "UV + CPL combo" (the UV layer adds nothing but reflections)
- Ultra-cheap uncoated filters that degrade image sharpness noticeably
- Buying before measuring your lens (mis-sized filters require expensive step-up rings)
Used for: shooting through glass storefronts or windows without reflections · making skies darker for dramatic building contrast · reducing glare on wet brick or painted surfaces · capturing details in reflective modern facades
