Re: [APML]: Best lens manufacturers

["John Petrush" <jpetrush@flosc.net>]

All the major camera makers offer fine optics today.  The resolution of 35mm
lenses it truly amazing.  Third party makers also offer excellent products.
I have personally used Tokina (300mm f2.8) and find it excellent.  My own
experience with Vivitar (non-Series 1) and Tamron were less than favorable.
That said, Tamron has made great strides in recent years.  I can't speak to
their latest offerings.

I would advise against a teleconverter if at all possible.  They tend to
yield mushy images and aggrevate any imperfections of the prime lens.  They
also cost you 1 or 2 stops in lens speed.  Yes, I have one and I do use it
from time to time for wildlife photography, but for astro work - never.
