A 52mm circular polarising filter in a phone clip mount

K&F CONCEPT 52mm Clip-on CPL Phone Camera Lens Filter Kit

SKU CH-916A-MHDYZ

Clip-on 52mm CPL filter kit with 18-layer coated glass reduces glare and boosts colour for phones and DSLR lenses

  • Size52mm
  • Cuts glare on water and glass with 18-layer coated AGC glass
  • Boosts sky contrast and colour saturation at 90° to the sun
  • Clips onto phones and fits 52mm DSLR threads for versatile use
  • Reduces reflections best at 30–40° angle to non-metallic surfaces
  • Lowers exposure by 1–2 stops, ideal for bright outdoor shooting

52mm Clip-on CPL Filter Kit

The kit pairs a K&F CONCEPT Nano-K series circular polariser with a universal clip, letting smartphone photographers add DSLR-style glare control to travel, landscape and street shots. It works with iPhone models 11 through 17 and threads onto any camera lens with a 52mm filter ring.

18-layer MRC coating and AGC glass

Japanese-imported AGC glass and an 18-layer multi-resistant coating cut reflections without shifting colour balance, so skies stay blue and clouds stay white. The clip holds the 52mm filter securely on most phone bodies, while the same filter can be screwed directly onto a compatible DSLR lens.

Bright-light polarisation with 1–2 stop loss

The filter darkens the scene by roughly one to two stops, making it ideal for sunny outdoor work where reflections on water or glass need taming. It cannot erase metallic or mirror reflections, and low-light indoor use will require exposure compensation or a brighter setting.

Questions about this item

How often will the 18-layer MRC coating on the Nano-K CPL filter need cleaning or replacement?

The 18-layer MRC coating resists reflection and glare; clean only when fingerprints or dust appear using a microfibre cloth and lens fluid — no scheduled replacement is required.

What is the first optical limit reached when shooting continuously with the 52 mm CPL filter in bright daylight?

The filter reduces light by roughly 1–2 stops, so the phone’s shutter speed drops first; increase exposure compensation or ISO to maintain the desired brightness.

Does the clip-on CPL kit add noticeable heat or battery drain during all-day time-lapse sessions?

The glass filter itself generates no heat and draws no power; only the phone’s screen and processor affect temperature and battery life during extended capture.
