Sigma 18-250mm f3.5-6.3 OS HSM Sample Photos

Here's a couple from Bailey Yard, North Platte, Nebraska. The largest switch yard in the world.
The first one is at 250mm, the second is a 100% crop of that. The 3rd one is at 28mm

Hi Parallax! Which OS did you turn off, cameras or lens? I love this lens but every think over about 200 kinda softish... K5@F8 min, monopod. BTW i used to do long haul, pick up couple of loads from that yard.

F8. I just realize that auto horizon correction can give me that soft focus...and my hand not as steady as they used to be... Some time monopod just gets on my way and i'm basically caring all handheld, monopod included... Magnificent photos, Liukaitc! Any plans for World Pentax day?
