10 out of 10 points and recommendedIt takes sharp images really fast!Well glass is heavy!
Well, I must start by sayingt hat this lens is amazing. I havent had the chance to compare it to the newer mark II but it takes really good images. I use it on a H sensor camera and the speed and lens combo is perfect. I get the 390mm at f 2.8 and there is no reason to use a higher f stop number. It is havy and i use it as a carry arowned lens for sports and wildlife. it works fine for me beeing an x triathlete but it gets to the heavy point at some times. I woudlent recomed that you walk further than 10 miles with it on your shoulder. The foces is really fast and the abilaty to take shots ad 1/400 of a sec in dusk is pretty awsome. I would higley recomend this lens.reviewed May 21st, 2012 (purchased for $4,000)
