I just purchased the lens used, and used it in the shot. Its a Sigma 24-60mm EX DG F/2.8. I was afraid of the comments I've read regarding Sigma Lens. I was happy to see that this Lens was in Great Condition.
I have to replace the Clear Lens filter that I have in it do to some cleaning scratches. Its a 77mm Filter so the $$$ is a little more than my previous 62mm... All in all Im happy with the quality this lens provides.
I took this into Lightroom tweaked the levels a bit. I also used the Localized Adjustment Brush and masked out the Flag with the Saturation brush. .
F/2.8 @ 1/200
