49mm filters: which lenses, which filters
70 lenses in our catalogue take 49mm screw-in filters, plus 1 fixed-lens camera. A 49mm filter fits any of them. Below: the circular polariser, 10-stop ND and variable ND to buy at three price points, with the price at each UK shop.
The 49mm filters to buy
Budget, mid-range and premium are the 25th, 50th and 75th price percentile among the 49mm filters of each kind we list, so the picks hold steady as stock changes.
Circular polariser (CPL)
Cuts reflections off water, glass and foliage and deepens a blue sky. The one filter most people should own.
10-stop ND (ND1000)
A 10-stop neutral density filter for long exposures in daylight: smoothed water, streaked clouds, empty streets.
Variable ND
A twist-to-set ND, typically 2–5 or 1–9 stops, for holding a cinematic shutter speed in bright light when shooting video.

Tip: if your lenses use several sizes, buy filters for the largest and use step-up rings for the rest. Prices are new-condition prices from UK retailers we track; GearFrame may earn a commission when you buy through a shop link. All filter sizes
