I am a casual photographer moving up from a point and shoot to a digital SLR and trying to decide between these two cameras. Does anyone have a comparison between the two? I am also interested in expanding my basic skills, esp. in the area of closeup photos of flowers, etc. and realize I will need various extra lenses but my concern is budget. Will the Evolt accept Sigma lenses? I've heard the Sigma 50 mmEX macro lens works well in general photography and it also fits better into my price range, but will it fit an Olympus Evolt? I've been leaning toward the Evolt because I can get one for less than $1000 with both a 40-150 mm and a 14 - 45 lens. Thanks for any help you can give this newbie.
