Back in June I chased a little beetle around with the macro lens for about an hour and never got a tack sharp image. This little guy didn't move at all so it was pretty easy to get a nice clear macro shot. The macro lens has an extremely short depth of field so capturing the sharpness at the point of interest can be challenging. Canon 40D, 1/400 sec @ f/5.0, ISO 800, 50mm macro lens.
From 365 Project The Air Force Memorial in glows against low hanging clouds and mist. Located on a promontory in Arlington, Virginia, overlooking the Pentagon and adjacent to Arlington Cemetery, the memorial's three 270 feet tall stainless arcs evoke the spirit of flight. Taken with a Canon 40D, 5.0s exposure at f/8.0, ISO 200, 28mm equivalent focal length, mounted on a tripod.
