Hi Stefan,
Well if you really NEED IS then the answer is not going to be easy. The
70-200 4L is a much sharper lens with better contrast. Even used wide open
the 70-200 4L will meet or beat the 75-300 IS used at its best apertures.
So the effect is that if you really do shoot in the dark you will only have
a good 1 stop advantage with the 75-300 IS at medium to long focal lengths.
Of course you will pay for IS on EVERY image you shoot with the 75-300 IS in
terms of softer images and slower apertures. This cost is on every image
even when you don't use IS so consider carefully if the 75-300 IS lenses
weaknesses are overcome by the value of IS.
Images that are not enlarged past 4x6 or so won't really show much
difference even with excellent processing. BUT if you print larger than
this or project slides the IS lens' shortcomings will become clearly
visible.
If you would only use a monopod the question would be much easier and the
70-200 4L would be the easy choice.
Something else to consider is that the 70-200 4L is also a much better
design mechanically and has "L" class lens construction. Compare it to the
75-300 IS with its pure polycarbonate structure and there really is no
comparison.
Cheers/Chip
