Misha, that bit of info helps clear the fog...salesmen who do not have the "digital" version in stock claim no difference..that is why I asked. I hope to see on the shoot experience and not believe all the hype, either way! Then again, if I am not shooting film( or plan to with the particular lens) the digital version may be the best way. I am wanting a nice telephoto zoom and that is pricy. And like all of us, do not want to be disappointed with the lens. Thanks for the imput. This does help! Tom. PS the part of light orientation is new to me. Thanks for that and light is something I do understand.
