I was always hesitant to use these and usually just relied on ramming my shutter speed through the roof. I'm pleased to say that I'm very happy with this item and its results. The clarity appears to be the same as without it. There's a slight color cast to the image but with digital this doesn't matter.

The first thing I checked was the colour cast that this filter might impart and any effect on resolution. The lens used was a Sony 24-70mm f/2.8 GM, a very sharp lens at 24mm. I found practically no colour cast and no resolution loss, keeping in mind that the sensor itself undergoes some reciprocity failure during long exposures (it's worse with film).

I'm very impressed with this filter. I just picked it up and wanted to compare it to my B+W 10 stop...the difference is huge ! The B+W leaves a heavy purple cast that is not very easily correctable in post. This one leave a slight one but very easily correctable...and at a fraction of the price !Money well spent I would say

slim line does not vignette on my 24mm zoom no artifact and allowed an 8 second exposure at ISO 100 f 8 on a clear sunny day. in addition the super fast delivery made it possible to start using it right away

I have had this filter for about 5 months and i love it. I prefer the screw on filter to the filter inserts, personally. I mainly use it to create motion during day time photos. Either clouds or water from the ocean. I feel that for the price is this a great option and a great competitor to some of the other brands that 4 times the price.

Beware of use with step rings. It is extremely difficult to remove if over tighten on to a step ring.
