Re: [APML] CANON LENSES FOR ASTROPHOTOGRAPHY

["DEREK BAKER" <derekb@sympatico.ca>]

Oh OH!

Have I started one of those Pepsi vs Coke or Chevy vs Ford wars? ' hope not!

Thanks for your feedback.

A question for you though.....Does Canon still separate their "L" series
lenses from their 'regular' ones? I don't recall seeing that designation for
their new EF series of lenses, which (for better or worse) are the only ones
that I can use, I believe.

What lenses did you find especially useful for astrophotography.

Your expertise is greatly appreciated!
