ROZAC:..,
first pic was
1/500s
f/6.3 (widest f-stop @ full-zoom)
ISO 200
BTW, those are the first set of nature shots off my new XSI
shot with Sigma 18-200 OS lens.
Second pic was
1/500s
f/5.6
ISO 800 (hence grainy looking)
(why? because i have problems holding my hand steady at almost full zoom, even with the OS on, plus it was an object in motion and the other shots with lower ISO were too dark and longer exposure made the subject blurry. Would like to do the shot over with a tripod)
3rd pic:
1/500s
f/6.3
ISO 400
Maserati, I do believe it's a Snakebird. I've seen it in the Wild Fowl Trust already. He may have hopped across the trees, and was sitting there from the time i arrived to the time i left, about 3mins.
