I always have B+W UV filter on my lenses to protect my lens, however, with the 85L F1.2, is that also recommended or just something you'd not want to put a filter in front of that lens? Can you see any image degradation with a high quality like these filters in front of it?
I think the difference is for pixel peepers who think that if they get that one pixel a little sharper then their photograph will suddenly have meaning. Just slap the cheaper one on there and happy shooting!

I would get the second one mf# 66-1066124 as that is the new and better model with Nano coating. The new B+W filters come in black boxes as opposed to sky blue/grey. This filter has a much thinner ring than most and you won't notice any vignetting that might be seen with wider shots with other filters. I'd use it over any other in the market.
You could also grab it from Adorama directly for 87.50.
