Hello, my budget for a lens is around $180. I will be purchasing the GF1 body only and need a lens. Which one out of these would be best bet in this price range; any other lenses out there? 1. Olympus ED 14-42mm f/3.5-5.6 Lens - $149 Used 2. Panasonic 14-42mm - $179 New 3. Olympus ZUIKO DIGITAL 25mm f/2.8 Pancake Prime Lens - $175 Used 4. SLR Magic 35mm f/1.7 MC lens - $100 New Do any of the above need any type of an adapter to work on GF1 (other than the Pany lens)?
