Farnborough 2010
This is one lousy lens when it come to photographing aircraft. It's resolution at the top end is pretty poor and focusing speed quite slow.
The workaround is to use my GF-1 not G1 as focussing seems quicker , never use less than 1/600 and try f8 if possible while adjusting the ISO.
Sports mode seems good for this sort of thing although the camera is usually left in shutter mode.
Photobucket processing doesn't do these images any favours but I can't wait to see if the new 100-300mm lens is sharper
