PMA 2003, 08:00 PST, 07:00 PST: Olympus has today announced that it will be exhibitting its first 4/3 rds digital SLR prototype at PMA 2003. As well as the prototype SLR (about which we know very little) there are also four lenses, two of which are primes, and two zooms. Olympus has made available images of these products including the lenses. As we can see the new 'E System' digital SLR looks very similar to the previous E-10 and E-20.
