Free Technical Help
Nikon and Canon have excellent live telephone support; they aren't like calling for help with a Windows PC!
Digital: (800) NIKON-UX, 24/7/365.
Nikon Film Cameras: (800) NIKON-US.
Nikon is excellent: they'll help you, regardless of the age of your camera, lens or scanner. They know better than I if your particular camera is defective or what accessory or lens works with what. They've helped me a lot over the decades. Have a problem with setting your D100 from 2002 or a Coolpix 900 from 1999 at 2AM? Just call.
For Nikon camera questions also try the Nikon Compendium.
(800) OK-CANON (except Sunday and late nights). Canon is also excellent - I also call them when I get stuck myself.
99% of the "What camera should I buy" and other technical requests I get can be answered by searching my site:
If on a budget, I always prefer used Nikon or Canon lenses to anything from Tamron or Sigma. Off-brands look good on paper, but the real measure of a lens are the subtle details inside that you can't see online or at a store. I've not found discount-brand lenses to be bargains, although the better Tokina lenses seem very well made.
If you still can't find the answer or have something interesting to everyone, please let me know, but remember, I can't possibly respond personally. I get hundreds of people emailing me every day, and I'm just one person who only gets to open his email about twice a month.
MANY, MANY THANKS !!!
