Also separately a lens for astro.
Your Pentax 67 - I am interested in the same 55mm F4 and also a 200mm F4 or perhaps a 165mm F2.8. How do you rate them?

I picked up off EBAY a very nice Sigma 50-150 f2.8 APO for Canon EF not so long ago , not had it on the stars much yet,but a few test images I took with it on the 40D were very nice. Pinpoint sharp stars everywhere.
I'm also darned impressed with some test images I took with another EBAYed lens I picked up not long after , a Tamron AD2all SP 300mm f2.8 LD with a custom made AD2all-EF adapter. Again very sharp stars everywhere in my test images.
Another nice lens that is worth looking for is a Soligor 135 f2 , if you can find one with either an OM PK, or Nikon mount even better (no lens in the EF adapter), I've one that I found on EBAY that has an FD mount so my adapter has a lens in it, but it is still a very nice astrolens (works out about 200mm f3 with the adapter) and while it's not LD or APO or L class, it still process nice focus on stars with very little aberation.
I been told by some folks in the USA that their old Nikon manual focus f2.8 zooms are great performers on a Canon DSLR.
Not all of us have the money to spend thousands on Canon Prime Lens and L type Zooms. And they ARE PRICEY , even more so here with usual distributor ripoff margins that are customary here.
