The manual for the A*300/2.8 doesn't say that it requires a filter in
there. I imagine if a place holder was required by the A*300, it would
have been supplied along with the lens.
I have a Sigma 300/2.8 that came with a "filter" in there. Also came
with a polarizer that fit in there & a pocket in the case to hold
whichever wasn't in the slot in the lens.

My A*300/2.8 has a filter drawer but has never had a filter in
there, will my images magically improve if I put one in? :)

Interestingly, along a similar lines, my 600 (and other Pentax
lenses with drop in filters) requires a filter in place for optimum
performance although I've never tested to see effects without a
filter.

Yup he lists exactly the situation I said you would see effects
in. Other than that has any one actually done any side by side
testing to see if they see any differences? Or is it just more
fun to argue without being hampered by facts?
And I mean test with one filter, not ten stacked up.
