Hi

I'm looking for a great zoom for my 50D.
I know the 70-200 f/4 L IS USM is great.


What about the 70-300 DO IS it seems very nice.
Nice size.

Is the range from 200 to 300 usefull.
What about the IQ.
Is the IS working good in the 200-300 range.

It's for outdoor use.
Travel, a trip in the forrest, sightseeing...
I don't do sport shooting.


Just a footnote:
I have the ef-s 17-85mm. I'm 90% happy with the IQ. Maybe upgrade to the new 15-85.
Testet the 24-70mm f/2.8 L. Didn't like it. IQ was about the same, but IS is missing. I need IS as I will never use a tripod.
