I was probably a little hard on Nikon.
Nikon has been very good to me over the years and I certainly appreciate everything they have done, but there have been times that I have not even been able to get them to answer my correspondences.
I purchased a Nikon Field Microscope
http://nikon.com/products/sportoptics/lineup/fmicroscope/fieldmicroscope/index.htm , which was in their North America Sport Optic catalog for a year or two, for my kids and have been trying for years to purchase the accessories that were shown in the Sport Optic catalog. I presented this Field Microscope to my daughter on her fifth birthday and she will be seven in less than two months.
WTF, if you go to the page linked above the accessories are clearly shown but by God as my witness I have spent at least twenty hours on the phone and have sent dozens and dozens of emails to Nikon trying to purchase these accessories and finally just gave up.
I bought this for my kids to use with the hope being that owning this optical instrument will help to start them on a life of inquiry into the natural world around them. My kids get a pair of good binoculars when they turn three, 6x30 Leupold Yosemite, and are encouraged to use everything we own, and we don't have junk. It just frustrates the living hell out of me that Nikon has been so damnably unconcerned that I cannot purchase the accessories for this instrument.
