A good test, but its ranking is not relevant to digital use. Lenstip evaluates and ranks those filters for their original purpose of cutting out UV. But digital sensors aren't sensitive to UV, so you only care about transmission in the visible light range. If you look at that, then the top filter in the lenstip results, Hoya HMC UV(0) is actually looking a bit worse than the B+W UV-Haze MRC, because it has a more irregular transmission curve for the visible spectrum, while the B+W has a smoother curve.

Check out Marumi Super DHC multicoated filters. I have both 49mm UV and CPL filters. I got mine on Ebay from oeccamera. Here's the link:

I would not bother with a filter for normal use of the DA 40mm, but if you insist you can get a 30.5mm filter and screw it on the inside of the hood.
