ASTRO: Mars & M-35 and Co.
4 X 45 sec taken with my Canon XTi with a Olympus 300mm f/4.5 (5.6) from my
backyard. I live in the burbs and the skies arn't dark at all. On a good night you can barely see the Milkway in Cygnus...this was not one of those nights. Joe |

Color contrast makes a great shot! How do you mate an Olympus lens to a Canon camera? Rick -- Correct domain name is arvig and it is net not com. Prefix is correct.

When I tried adapters on my old film SLR they pushed infinity beyond reach. Some truth to that but it's nice when an astro lens can achieve it anyway. I'd have to take the lens apart and reset the infinity stop which screwed it for for use on the original camera. They must make them better now. I gather that puts you in full manual mode which is no problem for astro work of course. Rick |

The Canon DSLR body has a shorter focusing distance between the lens mount
and the chip than the old film body Olympus. The adapter/spacer takes up the slack and focus is still at infinity...a perfect fit. Joe "Rick Johnson" wrote in message ...
