Thanks. I planned to start with wide angle anyway. 14 mm Samyang f/2.8, 20 mm Vivitar f/3.8 M42 legacy with M42 to EOS adapter, a slower zoom 15-85mm f/3.5- f/5.6, then 55 mm f/1.4 legacy Mamiya M42 with M42 to EOS adapter are the realistic choices. These combos could range from 0.9 to 1.5 kg including the EOS 60D.

Hi Nancy,

It sounds like you've got a good plan. I've been real pleased with my Samyang 8mm f/2.8 fisheye. And that M42 Mamiya 55mm f/1.4 is also a great little lens. It's best stopped down to f/2.8. Here's an example piggyback on a Celestron-8, Kodak PJ400, ISO 400 film, full frame, 17 minute exposure.

North American Nebula in Cygnus

Best Regards,
Russ
