At a glance: The Urth 77mm Circular Polariser Pro is Urth's top-grade polariser for 77mm lens threads, with SCHOTT B270 glass and a 34-layer coating.
About this accessory
The Urth 77mm Circular Polariser Pro is the top tier of Urth's polarisers. It uses SCHOTT B270 glass with a CoraNano Max 34-layer coating on both sides, and Urth states reflectance of 0.5% or less. The frame is warp-resistant, aerospace-grade aluminium.
It is built for strong glare and reflection removal while keeping colour transmission neutral, with a slim frame designed to avoid vignetting. Choose it over the Standard or Plus+ polarisers if you shoot on a large 77mm lens and want the best coating Urth offers.

Frequently asked questions
What lenses take the 77mm Circular Polariser Pro?
It fits lenses with a 77mm front filter thread. Check the ø figure marked on the front of your lens or on its cap. A lens marked ø77 takes this filter directly, and the lens manual lists the thread size too.
How is the Pro polariser different from Standard and Plus+?
Pro uses SCHOTT B270 glass with a 34-layer CoraNano Max coating and a stated reflectance of 0.5% or less. Plus+ uses a 20-layer coating, and Standard uses Japanese AGC glass with a multi-layer coating.
Will a polariser darken my images?
Yes, a polariser absorbs some light, so expect a slower shutter speed or higher ISO. Modern cameras with through-the-lens metering normally account for it.
Can I use the 77mm size on smaller lenses?
Yes. A step-up ring from the smaller lens thread to 77mm lets you share one larger filter across several lenses, which is often cheaper than buying one filter per lens. Wide-angle lenses may show vignetting with a ring fitted.
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..
