Forget silly reviews. best way tho judge gear is to try it out. weekend shoot at NYC with the D800 coming up so I'll get to test it some more with lots of diverse conditions. Looking forward to night shooting and using a 2x TC on a 300 f4 and some other glass. I'm hoping the touted ability to focus with f8 effective apertures works to my expectations. I'm meeting a lucky MK3 owner to compare notes and test the others gear. Maybe I'll convert him
