I'm still looking for my next digicam (meanwhile still shooting my very old\none... depressing !).\n\nI went to a store and compared the Oly E-500 with the Pentax K100D. Not really\nany difference in size ; so since I think the K100D is a better camera, it\nwould win. Now where it really opened my eyes, is that I think the size of\nthe bodies is about right, the problem is the size of the lenses....\n\nPentax has a few pancake lenses that are very promissing, unfortunately\nnot really any small zoom. Is there any such thin lens in the 4/3 world ?\n\nWill there be ?\n\nIs it physically possible to make a, say, 18-55mm zoom (or 14-50mm in the 4/3\nworld) zoom that would be no thicker than 2 or 3 cm ?
