Hi Mike, I've frequented Ken's website over the years to. Right now I have a Nikon D300s and a 16-85dx lens and a Tokina DX 11-16mm lens. The Tokina is pretty nice...it's what I took my whole room pic with on my system page.
I might have to try the 50mm lens...I've been also wondering about upgrading to the D600 and the FX format...Thanks for the info
