I have the olympus sp550uz ... Archived Products > SP-550 UZ and i would really like to get something a little better. dont get me wrong, this camera takes great pics but i do a lot of cropping and its only 7mp so i am looking for 10mp and up. i have several questions: 1: Canon or Nikon? 2: i love the 18x optical zoom on my camera...how can i get even better with a digital SLR w/o spending thousands of dollars on lenses? 3: is that what a telephoto...zoom lense does...lets you zoom far away like the optical zoom? I will only go as far as the optical zoom will let me as i hate the results from digital zoom. 4: some of the cameras i am looking at only have 3x optical but come with 18-55mm Kit + 55-200mm VR Image Stabilization Zoom Lens....is that a good lens? 5: will a nikon lens work on a canon dslr? 6:here are some that im looking at...remember, im still new to this and dont want something high end..just a minor upgrade.... A: Walmart.com: Save money. Live better. B: Walmart.com: Save money. Live better. or just the canon eos digital rebel Xs Ultimately, should i just hang on to my camera and maybe get some lenses for it?
