Reflection/ghosting with B&W UV filter
I recently switched from an uncoated Tiffen to a coated B&W UV filter for protection on a 16-50mm Tokina lens.
The filter is: B&W 77 010 UV-Haze 1x MRC
And guess what? with direct light streaming into the lens I'm still getting green ghosting from the B&W filter. I was under the assumption that B&W filters are so superior that this should not happen. Perhaps it's because this particular lens design makes it hard to prevent ghosting...I don't know. Anyone have similar experience with B&W filters?

Any filter increases the likelihood of flare no matter how well coated. While the B+W is a far better filter than the uncoated Tiffen, you are still better off following Nikon's recommendation and removing the filter when shooting towards a bright light source.
In my experience the MRC coating is no better than that on Nikon filters or the higher-end Hoya filters. Nor have I seen any tests showing a significant advantage in flare resistance for the B+W.
I own B+W 010 MRC's, and like the brand due to the brass filter rings and ease of cleaning. If I was in the market today, I wouldn't buy the 010, but I'd take a hard look at the 007 clear protector and the Nikon NC. Neither standard Nikon dSLR's nor your 17-50mm lens benefit from additional UV filtration.

Flat filters, no matter how well coated, have limitations shooting the way you want to shoot.
The likely source of the problem is the extremely shiny surface of the sensor reflecting some of the direct light streaming into the sensor.
Flat filters tend to reflect more light back into the lens than the more expensive curved glass on the front of the big lenses; or the curved front element of a lens with no filter attached.
If the light is strong enough you can get this type of problem without a filter, especially with a wide angle zoom.
If you do some control tests with and without filter you can learn when you get the problem - even with no filter
Digressing Nikon's 14-24 can suffer this type of problem - it is not designed to take a front filter.
Photography is a bit like archery. A technically better camera, lens or arrow may not hit the target as often as it could if the photographer or archer does not practice enough.
