This was an emergency buy and for once my emergency buy did notcome to haunt me.It feel quite sturdy and has a smooth ring, the filter does not make any noise for once as Ihave had previous filters that made some noise.It did not get 5 stars unfortunately as the lens hood did not fit when the filer is added.A nice feature that this has is that it is threaded on both sides.

"VIDEO TESTED with Osmo X5" For the price its a great deal! But dont expect miracles! Its good but dont set it to the max because you will see ugly weird vignetting. I find it very useful for fine tuning your exposure so for me its great because i dont have to remove the filter and swap it you just adjust it to your liking but you cannot set it to max cuz the image quality is greatly affected. tested one day only but i will be using it for the week to come in different environments.

An acceptable compromise for separate dedicated ND & Circular Polarising filters . Interference pattern & colour cast (warm red) about two stops from full polarisation . The 46 mm dia filter supplied in a large 95mm square plastic box, you need large coat or camera bag pockets for this box.On the plus side a slim filter so no obvious vignetting & functions well until you approach near the maximum setting ; despatched from Japan so it took 14 days to arrive (advised delivery up to 28 days) not a problem for me but possibly for others who need it now .
