Cheap adaptors fine for astrophotography
Aaron,
A while ago I bought a Canon DSLR for astrophotography, with just the standard 18-55mm zoom lens. Whilst this was OK for general nightscape shots, I wondered if there was some way to use various Olympus/Zuiko lenses I had from a 40 year old SLR, which were optically superior, eg F1.4.
From internet searches, I sourced adaptors from the US, which cost less than $30 posted and work fine. Of course, they are only mechanical adaptors and you can't use the automatic electronic functions of the EOS, such as auto-focus, auto-exposure, etc. But for astro work you focus manually and set the f-stop and exposure manually, so this is not a problem. I understand you can pay a lot more (>$100) and get adaptors which adapt mechanically and electronically, if you wanted to use the DSLR for full automatic daylight photography. The ones I got were "Fotodiox" brand, which have been trouble free. Worth a try! And will save a lot of money, compared to buying equivalent Canon lenses.
