Ye, there is adaptor for the E-1 and E-300 which allows manual use of
these lenses on the DSLR body.

I received a "free" OM adapter when I bought my first Olympus E-1.
The second body I bought did not include the adapter, but they can be
purchased separately.  Having said that, I have only seen the adapters
sold separately in the USA.

The lenses effectively double in focal length because of the small
size of the sensor.  For example, a 50mm f/1.8 becomes the equivalent
of a 100mm f/1.8 because of the smaller angle of view.

I have to say that I have been disappointed with the results, and I
only use Zuiko Digital lenses on my E-1s.

The E-1 is a 5 megapixel DSLR with a rugged body and excellent
weatherproofing.  For amateur use, Olympus are about to release the
E-300 which has more than 8 megapixels but it is not built for hard
use.  However, I guess that it will be more than good enough for most
amateurs and the price is likely to be very attractive.

Hi John,

The short answer is no.

Before digital, as you will be aware, Olympus had not made a new slr body
for say, 10yrs, though that's a guess.

Anyway, their new crop of digital bodies are based on the digital 4/3rds
system as Olympus have basically started a whole new body mount from scratch
and have around 15 lenses available now.

Their lenses are designed for the chip inside the camera, unlike on other
makes where adding a 35mm lens to a Canon/Nikon/Fuji/Sigma, etc... adds
around a 1.5x magnification due to the chip being smaller than 35mm.

Hope this helps and if you still want great images from your lenses, stick
with your 35mm and get a dedicated film scanner for these lovely dark winter
nights.

Cheers,
Stephen
