Well, here I go again. Damn lens lust, it's incurable I'm afraid. Here goes. I have the 18-70 that came with the D70 and like it very much. I have the opportunity to pick up a 35-70 2.8 at an incredible price from someone I know. I can't find a single review on it except Ken Rockwell, and he was not helpful. He's never even used it. Here's the dilemma :?: , I know I'll lose on the wide angle end, but what about quality? I love that 2.8. Opinions/comments greatly needed & appreciated. Thanks!!!
