This is high quality ND filter. And it's package like Giorgio Armani products ;-)

Merci reçue et satisfaite!

These are not cheap but comapred to Lee Filters a bargain. The filter holder is excellent, and is supplied with multiple adapter rings, which are £26 each from Lee. I can see no significant colour cast. So if you want to experiment with proper filters without breaking the bank these are a good buy. The filter cases are beautiful and the whole product presentation/packaging oozes quality.

Tried the filter a few times with landscape shots. Worked really well. Not affecting image quality or producing colour cast. Very happy with the product and purchase.

Excellent with little colour shift which isn't really relevant with post processing. Found it a fraction out in real world testing in stops and no great loss in sharpness but I'm just nick picking. Do your own tests to find the perfect settings. At the price it's good enough for most photographers.

Bought this for my wife as I also have the same filter. Found hardly any colour cast & very clear.

not very easy to put the adapter into the filter holder. and when it is in, the rotating is not smooth. i tried two adapters, the same.

Excellent filter and quaility

I haven't had the change to do real world testing yet but I've taken a few test shots in my garden to check for loss of sharpness and color casting. I used a macro lens for checking fine detail and wide angle to see if its consistent across the frame. I also checked it against my Lee Filters big stopper.I couldn't find any percievable loss of sharpness across the entire frame with the macro or wide angle.There is a bit of a color cast to it from looking at the exif data but shooting in raw the camera adjusted it out for the most part and can be edited out manually if required. Importantly though it seems to be consistent across the entire frame, even at 10mm on my apsc sensor.I did experience vinetting on the wide angle (both 10mm and 22mm) but again it can be edited out very quickly in lightroom.It would have been nice if it came with a light gasket supplied with it but for the massive price difference compared to the bigger brands I can forgive them for that. They can be purchased online elsewhere if required which is what I'll be doing.Overall I'm pretty happy with it, which is just as well really as it managed the slip through my Lee Filters folder when I wasn't paying attention and drop onto the paving slabs in my garden, which chipped the corners of the glass. That's my own fault though as it's a known issue I have with the holder, I experience the same problem with my Nisi filters in my holder so I think it's a bit worn out.
