I use a Canon EOS500 with three lenses;
Canon 35 - 80
Canon 70 - 210
Cosima 100 - 400
My experience is however that most of the time it is the scanner that makes the work worth it to added.
Till may this year I'm used the HP 5200C with gives me at the end (Not speaking at a year ago) a success of 80% added to the database. I bought a new scanner in june, the HP photosmart S20 and guess what, I have now 99% accepted to the database and most (95%) without warnings. On this moment I have 2.300 photos at A.N.
p.s. Thx all to use this forum, I'm learning every day from you.
