This is Angela, a petite freelancer model in Malaysia. I shot this using the Sigma SD15, unfortunately i got the usb dock 1 day late and it seems some of the images are front focusing. But i did manage to get some usable and nice ones and edited it.
The 18-35 1.8 ART is an amazing lens with ONE big con…it has not image stability. The lens is heavy though, so you will need to support it to counter the shakes.
