I received my D7000 with the zoom kit (18-105mm) and took it to my kids' soccer games this past weekend. Didn't take long for me to realize I need a higher zoom lens.... but don't want to spend too much money on lenses (at least not yet) nor lug around something too big. Another factor to be considered is taking it on vacations and fitting it into the LowePro Slingshot 202AW bag that I just purchased. I've narrowed my choice down to either a refurbished 70-300mm VR or the new 55-300mm VR. I read a ton of fantastic reviews on the 70-300mm but haven't seen much on the 55-300m. B&H has a refurbished 70-300mm for $400 and a new 55-300mm for $360, so not much price factor. The 70-300mm is slightly bigger by .1x.8in (Diameter x Length) and weighs 7.6oz more than the 55-300mm, which I feel is negligible. The 70-300mm has a bigger lens at 67mm than the 55-300mm with a 58mm lens, but not sure if this will impact picture quality. So the question is, should I go with the new 55-300mm or go with the refurbished 70-300mm that seems to have been a proven performer for the past few years?
