as I stated earlier I have been using a canon 1d3 and a sigma 150-600 sport for a few years now ,but age (galloping towards 73) and general aches and pains have slowed me down to the point of not even attempting long walks etc ,even mounting the camera and lens on a tripod and gimbal became to much to even shoulder mount . my initial plan was to go for a sigma contemporary lens to lighten down the load ,but the salesman in the shop said why not look at micro two thirds as things have progressed in the last couple of years .
I put the question up on the u.k based talk photography forum " does any one use Panasonic or Olympus for wildlife" and was inundated with replies and links .to be honest I was blown away with some of the i.q I was seeing . myself and my son then took a trip to our local retailer who knows us both so allows us to take cameras and lenses out around the city centre for trial shots ,using our own cards .after putting them on the i.mac I went back the following day and bought the g80 ( the g9 is far to pricey in the u.k but one day) its the g85 stateside and the leica 100-400 this is a dream combo and all up weight is less than 3lbs ,it also gives more reach than the sigma sport and focusses down to just over 4 feet . to
you also have to take that sublime 2 x crop factor into account so effectively your getting 200-800mm focal length . I was warned that there might be noise issues with the smaller sensor but the latest sensor technology seems to have subdued that to a manageable level .have I made the right move probably yes for me on a personal level as I tend to like to go walkabout and just take wildlife as I see it appear ,the rig is certainly fast enough to focus and the evf keeps up with birds in flight easily .time will tell so keep watching this thread for updates .
and as a bonus I might not have people coming up to me going thats a big lens ,is it expensive etc etc etc
