Fully & completely. When I ordered my camera almost 2 years ago, I tried to order the kit lens with it. Thankfully, my dealer did not have in stock & couldn't get. I've rented & used the kit lens exactly once in two years. And while I know the Sony wins in pricing... the $ I saved in not buying that kits lens has definitely gone into better things. I'm thinking same may be true for this better focal range one. I try to take the long view now in glass buying decisions. Can I use on multiple cam systems? Will it hopefully retain most of it's value over years of use?I would certainly want to try it side to side with the 18-105.
