Hi All,
I too have just upgraded from my Pentax to the new Canon 40D DSLR.
The L series lenses are way out of my budget right now so I hope some IIS members can advise on the best
non-L lenses to use for astrophotography.
The 50mm f1.8 seems a no brainer for the price. But, I'm wondering about the CA in the the 85mm f1.8 and 100mm f2 lenses.
Any information appreciated.
Cheers
Doug
