7 d focus
May 18, 2012

Hello i have just purchased a secondhand 7D, shutter count 4000 according to dealer ,with 6mths G/tee .it seems to focus fine in normal use ,but I want to use it for bird photography and have been testing it out on the small birds at the hanging feeders in the back garden ,using a Canon F4 300 mm is lens at a distance of 10 ft,shooting at 1/500 with 800 iso, resting the camera/ lens on a bean bag .the 7d would not produce in focus photos ,I then stopped the feeder from moving about ( due to wind bird moving etc) and the focus improved (see sample ) am I expecting to much from the 7D for it to be able to focus on a small bird swinging about on a bird feeder ? ,Also does the sample look sharp enough or is it below par on focus ,i know it appears to dark now uploaded and the composition is not great but Im only interested in the focus issues at the moment any feedback gratefully received,
peter
