I’ve been practicing with an Olympus E-500 for over a year now and would like to upgrade to a better camera sometime next year. I would like to upgrade from the Olympus 40 - 150 lens at this time that I received with the camera to an Olympus 50 - 200. I have an opportunity to purchase a seldom used .. non-SWD lens .. at a very low price from a friend.
My question is … Is there that big a difference between the SWD lens and the non-SWD lens to justify paying twice the price?
