Used with the Leica M8 this filter works excellent! At a fraction of what the Leica filters cost. The build quality is also great.

I bought this filter in two sizes to use in my Fuji IS-Pro just to have more versatility. So I can get natural visible light results with that camera as well as I can capture infra-red images with no filter or using special IR filters.
The fact that the filter cuts the unwanted UV and IR lights by interference, rather than by absorption sounds like magic or trick. Amazingly, it really works! Pictures taken with this filter show no trace of the effect of infrared light. So, a light and thin coated glass can do the job., but…
The problem comes from the same properties of interference given by the coatings: the interference varies with the angle of incidence of the light on the glass. This renders this filter unusable with wide-angle and even normal focal lenses, resulting in a greenish gradient from the center to the corners. The center may be neutral, according to the proper white balance, but the green color cast is clearly perceptible around it, the wider the angle. My careful tests have shown that only lenses longer than 50mm (short telefoto) may give acceptable results.
That throws away the versatility that I expected from that camera and so I just carry it when I plan to do IR images. So this expensive filter has turned practically useless for me.

This is a nice, high quality filter.

I've been buying B+W filters for years. My recent purchase of a Leica M8.2 necessitated the need for a CUT UV/IR Filter to counteract the magenta cast because the M8-M8.2 is lacking the equivalent in front of its sensor.The camera came with the proper Leica CUT UV/IR filters, but they just felt 'cheap'. They were probably fine, but I'm told that they were made in Japan to Leica's standards, possibly by Hoya.Since I was familiar with B+W's quality brass mounts and German Schott Glass, I sold the Leica filters to buy the ones from B+W.I have not regretted this decision. [...]I highly recommend B+W filters as well as B+H Photo.

I bought this UV/IR filter to cut the magenta cast I was getting on my Epson R-D1. What more can I say? It works and it's wonderfully well built. And with the MRC coating, I can leave it on all the time to protect my lens.

I am using this filter on a Zeiss 35mm Biogon lens when attached to my M8.2. This filter blocks IR radiation which might yield to color shifts on black fabrics due to the very thin filter in front of the camera's sensor. This thin filter on the other hand results in excellent detail rendition compared to solutions being implemented in most DSLRs. This B+W filter is very well made and fits firmly, as usual with B+W products.
