In reply to rockwing:
Hi, do you mean SLR or DSLR? The OM1 is an SLR i.e. not digital....
The trend is away from DSLR's to mirrorless cameras which offer similar performance in a smaller package
If you're looking for a compact interchangeable lens camera ILC... you'll find lots of recommendations for mirrorless Olympus & Panasonic hereabouts these being compact ILC's with a micro four thirds size sensor. Fuji and Sony (and Canon & Nikon) also do compact ILC's with a larger sensor.
Much depends on expected use, price and what you like the feel/look of. If you plan to get additional lenses it is also a good idea to check out the available lens range. This is currently a weakness for Canon and Nikon.
