Hi all -- yes, I'm a noob to the world of interchangeable lenses, so please be kind. I bought my lil refurbished ELP-1 a couple of months ago to help me learn how to take good photos for my work (I work for a nonprofit and we never have decent photos for our newsletter). Anyway. Enough about me; let's talk about you. What it is that you like about the Olympus 17mm f2.8, besides how small and unobtrusive it is? In what situations would you choose to use it over the 14-42 IIR zoom? And why? Thanks for all your help! You're helping a noob become less so. A.
