Sigma 24-70mm EX DG f/2.8 Macro - examples, p.2

I'm really liking this Sigma 24-70mm EX DG f/2.8 Macro lens. It has very high image quality, even wide open. Attached to the K-x it fits beautifully in the LowePro TopLoader Zoom 50 AW bag. Just thought I'd mention that if you are in the market for one.

f/5.6 @ 34mm



f/6.7 @ 24mm



f/6.7 @ 43mm

What shutter speeds were these shot at? There seems to be a little bit of distortion around the trees in the distance, and I'm wondering if it's due to motion blur, overexposure, or simply being outside the DOF.

1/1000, 1/250 and 1/180 respectively. I think it's mainly due to the fstop, depth of field isn't as great and may be causing the blur somewhat. I'm trying to remember if it was a windy day... short memory ;-). Might be a combination of both? As for the distortion I was quite a bit lower than the building therefore it bowed the trees slightly. I'll get better examples soon!
