I have just bought a
Tamron SP 300mm f2.8 LD IF and while searching for sites with more
info about it I came across a lens test with a remarkable
finding...As you probably know, Tamron used to offer an optional
112mm "normal" filter for the front of the lens. I dont know what a
"normal" filter is but apparently the tester has found his Tamron
300/2.8 to be considerably sharper with this filter on the lens than
without it!!!

I had a similar experience with Canon 1D MkII and long lenses. A UV
filter improved AF performance of the camera.

That may or not may not be the case with AF lenses but it should'nt effect the focussing accuracy of manual focus lenses at all, and the Tamron SP 300mm f2.8 LD IF in question, is a manual focus lens.
