At a glance: The Urth 37mm Circular Polariser cuts glare and reflections from water, glass and foliage, and deepens colour, on lenses with a 37mm thread.
About this accessory
The Urth 37mm Circular Polariser is a rotating CPL filter in Urth's Standard tier. It uses Japanese AGC optical glass with a multi-layer nano-coating in an ultra-slim aluminium frame, and screws onto lenses with a 37mm filter thread.
It suits shooters who want a polariser without paying for the higher tiers. Because it is circular, autofocus and metering work normally, and some exposure compensation through shutter or ISO is needed as it absorbs light. Plus+ and Pro are the upgrades.

Works with
- Lenses with a 37mm filter thread
Best for
A practical first polariser for hillwalkers and outdoor photographers who want deeper colour and less glare. It works on still and moving subjects. A 37mm thread is a small one, so check the ø mark on your lens to be sure.
Frequently asked questions
Will the 37mm Circular Polariser fit my lens?
It fits lenses with a 37mm front filter thread. Check the ø figure marked on the front of your lens or on its cap. A lens marked ø37 takes this filter directly, and the lens manual lists the thread size too.
How do I get the best effect from a CPL?
Screw it on, then rotate the front ring while looking through the viewfinder or at the screen until reflections fade or the sky deepens. The effect is strongest at roughly 90 degrees to the sun.
How much light does a polariser lose?
A polariser absorbs some light, so expect a slower shutter speed or higher ISO. Cameras with through-the-lens metering will usually adjust for you.
Does a 37mm filter work on a small or compact lens?
This size is made for lenses with a small 37mm front thread. The ultra-slim frame keeps the added length down, which matters on compact lenses.
Why buy from Bass & Bligh
Bought from a real shop, not a warehouse.
Dispatched on the Monday… great service
Ordered a Panasonic four thirds lens dispatched on the Monday after purchase and delivered on the following Tuesday great service. Tried on the camera and initial thoughts are wow pin sharp and clear photos. Thank you
George P.Ordered a lens onlineA proper little treasure trove
3rd time I've been to this shop to treat myself to some new kit. Always very friendly and knowledgeable. Fairly priced too. I would highly recommend a visit if your nearby and looking for camera gear. I'd say if they don't have what your looking for, it's probably not possible to find anywhere. It's a proper little treasure trove.
Philip B.Third visit to the shopBrilliant advice with awesome customer service
Sure you can buy online and possibly save a few pounds.. but if you require and appreciate knowledge and brilliant advice with awesome customer service then it's a no brainer...This is a real camera shop like it used to be back int day..
