I own a G9II and am thinking of buying either the Lumix 40-200 Mega OIS for $193.00 or the second version with Power OIS for $300. My reason for buying is to fill in the focal lenggth gap between the 35-100 and 100-400. Is it worth spending the extra $100.00 I would be using it as a walk around lens. My other lenses (all Panasonic) are:
20mm f/1.7
7-14mm f/4
12-35mm f/2.8
35-100mm f/2.08 Power
100-400 VII f/4-6.3
