Thanks for sharing the results of your hard work, and likewise to Gary
Reese.
The optical standards Gary uses to rate lens performance and the effect of
filters I think are far more demanding and objective than my own and I
suspect, that of many others.
I generally remove UV/Skylight filters when shooting with the Sun within or
close to the frame, shooting high mag. macro and when I am striving for
maximum contrast and sharpness. Having said that, shots where I've left the
filter on do not appear to be significantly lacking in the contrast and
sharpness department.
>From my perspective, if I find my images consistently compare well,
projected on screen or under the loupe, to what fellow shutterbugs are
producing, then I consider myself on the right track and look to other areas
where I might improve my photography first, rather than change the optical
hardware I'm using.
At present, I reckon I can improve my photos more readily by working on my
subject selection, framing, DOF control and focussing, use of light and
polarising/color correction filters etc, rather than having a UV or Skylight
filter up front or not IMHO.
