Nikon 16-35mm f4 G AF-S ED VR Lens. This lens is PURE AWESOME!!! After studying the metadata with my 24-70 lens, I realized that I constantly shoot at 24-35mm. Hence this 16-35 is a suitable replacement for my Sigma 24-70 (*Sold) that SUCKS at 2.8 anyways. I can get perfectly usable handheld images (with proper technique) as low as 1/16 with the VR turned on. *UPDATE...since purchasing my Sigma 35 Art I really only use this lens for super wide shots or hella close-ups.
