Mayna ~ Another Test Shot with Sigma 18-200mm

Another test shot taken using the new Sigma 18-200mm OS HSM & Nikon D40. Its been just a couple of days and I'm yet to get a hang on this lens. I'm still unsure of its "Sweet Spot" ~ the aperture & shutter setting wherein the picture is pin sharp & at its best.

Most of the times, I just forget using the OS button while trying to go shake-free and as you can see in this picture, its not as sharp as it could have been. Need to find more time to play around with this lens and get a real hands on to ensure that the viewers and myself get to view some great pictures.
