I want to use my older Olympus Zuiko lenses from my OM/2 on a digital camera and am currently investigating what to buy. I've looked at the Olympus E-PL1 and it looks very nice , small and light just like the OM/2. I've read that using the older Zuiko lenses doesn't preserve the original focal length of the lenses. From what I hear its about a 2:1 ... a 50mm Zuiko will be like a 100mm on the E-PL1. Is this focal length change specific to 4/3 digital cameras ? Or would this also be the case when using the Zuiko lenses on other digital cameras or SLR's like the Canon Rebel XS etc. ?
