Hi,
I am new to digital photography having started this year really when I purchased a
Canon EOS 450D and as I am interested mainly in wildlife photography recently invested in a Sigma 150 - 500mm F5 - 6.3 APO DG OS lens.
I am trying to remember everything I am reading and to put it into practise in the attempt to get clear shots but I am finding a lot of the pictures I take are out of focus especially at the high end of the telephoto range even using the OS and a fast shutter speed.
I tend to shoot on AV mode using evaluative metering and the lowest ISO I can without losing shutter speed.
Also i notice I am getting what I call 'ghosting' around the subject when shooting white birds on water such as Egrets and Swans etc.
I would really appreciate any pointers anyone can give me even if it just reassures me that I am on the right path to a clearer result.
Many thanks.
John
