I use a 12-60 and a 100-400, both Panasonic/Leica lenses on a Panasonic G9. As its 4/3 format the lenses work as 24-120 and 200-800 when compared to 35mm/full frame. What really helps on the long shots is the double image stabilisation, both in body and in the lens working together.What lens on your camera Farmystu?
