for Kumbnutz......here is the side by side comparison
DSC_7967.jpg
As you can see , the difference is substantial.
- 1.6kgs Vs 2.3kgs
- one is significantly wide and longer (particularly when you remember to add about 80mm to the length of the 200-500 when fully extended to 500mm (see image #5 above) whereas the 70-200mm does not change length when zooming)
- both are reasonably well balanced but the 70-200 holds its balance well at all focal lengths whereas the 200-500mm is likely to change a little when fully extended
- they are quite different lenses for different purposes and have their own character and handling characteristics.
