I took this shot of my lens cap with my New Sigma 50mm Macro. Its really a happy accident as I was just looking around the house for items to shoot and the lighting was just too low to shoot much so I put the lens cap under a lamp and shot and It was the only shot I took of the cap.
if you were wanting to use this say as a promotional shot or something then you'd want the entire lettering in focus..but if that's not what you want then never mind!
And it's just the corner that needs to go.
Nice color, too.
