I recently got the 82mm 10 stop from Haida. Got to know about this little gem from Dustin here in CR. It uses the same Schott glass B+W uses in their filters. The Haida filter is known to produce a slight blue cast, which I have not seen that much in hundreds of photos I had taken just a couple of weeks back. Here is a photo I took with the Haida filter on it, straight out of camera. The only thing I did was change the profile to 'Landscape'. I did not bother to play with the WB at the time of uploading this. Also, I could auto focus with the filter on with no problem.
However after taking nearly hundreds of photos with the filter on my recent trip, I did realize one thing. It often became annoying to take off the filter to take normal shots, and only finding yourself putting it back on for long exposure shots time and again (I was not carrying a second body). The filter only cost me $80, and it's MRC (Multi Resistant Coating). I did not notice any loss in detail or clarity. I too was waiting for Lee back then before getting this. Frame's quality - I felt B+W's brass frame is better, and noticeably heavier than Haida's one. I often stored the Haida filter in my jeans/jacket's pocket. It got knocked around or the glass got hit by something or the other quite a bit and did not get scratched once...yet. Overall I am pretty happy. I checked out some reviews of in a flickr group discussion thread before diving in. You could get some more insights regarding this in that group if you are interested.Twilight and Tranquility II
