Help! I shoot weddings with my trusty A2E bodies and L lenses. I use both black & white (60-70%) and color film. My questions are: (a) How much better are the EOS3 and EOS 1V than the A2/A2E/EOS5? What would I gain by upgrading? (b)For the cost of the EOS IV, should I consider the 10D instead? Remember, many of my subjects are PEOPLE. I see beautiful product & scenic (non-skintones) images taken digitally, but less digital people photos that are at least as good as film. THANKS.
