K&F Concept 67MM Polarising Filter Circular Polarizing CPL, Ultra Slim, Japan Optics, Multi Coated, with Cleaning Cloth (Nano-K Series)

I'm very impressed with this filter - it may be Chinese made, but the optical quality is excellent (I look at the refraction as I hold the filter and turn it from side to side - any movement in the image will effect the optical quality, especially on wide angle lenses)The mount (for a 39mm filter) is quite chunky, but is screws on to the lens just fine and does what polarising filters are supposed to do.Although not a problem with this one, if you ever have difficulty removing a filter from your lens, put a rubber band around the circumference and this will enable you go grip the filter and unscrew it without squeezing and distorting it, which makes it tighter.Heartily recommended, and I will be buying more K&F filters in future now that Hoya are so expensive!

It's been my 1st CPL so was not 100% what to expect. Looking through the filter or with the filter attached to the lens it's not clear which is the polarised part of the fliter. However attaching and looking through the view finder whilst rotating, particularly when directed at the sky or water, it becomes clear when those parts are being 'polarised'. Definitely reduces the glare of water reflections and adds saturation to blue skies.I have no idea if the more expensive CPLs on the market will provide a better end result as this is the only one I've ever used. But so far it's delivering the results I was after.

excelllent build quality and great price

Seems to work as expected. Excellent value

This was bought for my Panasonic DC-FZ82D camera. It fits nicely and works well insofar as it reduces reflections.However, it also significantly reduces the transmission of light through the lens. This is a problem when trying to photograph pictures and items in galleries and museums which are behind reflective glass; there is little enough light in those situations.It's a long time since I last used a polarising filter and I don't recall the loss of light being so great in the past. Maybe a more expensive filter would allow more light through while still effectively blocking reflections?

Filter can't hold the fuji cap. Only tested on 72 as don't want to open the other unnecessarily. It seems there's just not enough space on front thread for the cap to latch onto. It is also a bit dark and definitely not colour neutral (warmish) Shame, as otherwise appears well built.Edit: upgrading to 4* as un the meantime bought several other products I'm happy with and also got offered free replacement filter, which is working very well.

Great fit, perfect for taking the reflections of surfaces, works perfect with my other filters

Great item
