Steiner Predator Pro 10x40 Binoculars
 

Has anyone used these Steiners? I like their autofocus feature in the Steiners. Additionally, they're slightly cheaper than the Nikon Monarchs..

I also like Steiner 8x30 Safari binoculars because of their auto focus feature. However, I've been reading in the forums that 10x42 is a preferrable size. Additionally, the predator series has an additonal coating that claims to pop out the browns in a green background.

Any advice?
