Shot with the D800 & Sigma 150 F/2.8

Focused manualy using liveview, it doesn't flip the mirror anymore (my D300 does) so it can be used without introducing camera blur
I did a focus stack , 15 image or so, all images 1/6 sec f/5.6 ISO 100
Wireless trigger

here is the full image


here is crop of the center of the flower


I'll say this lens works well with the D800

sorry for the showoff
