Hi,
Thanks to all who responded. I apologize for my absence during the discussion. After posting my question, I had the great idea to upgrade my operating system and took my iMac to the Apple store. It was upgraded in less than 2 hours. When I got home and turned on the computer, the system was totally dissimilar to my Snow Leopard. I spent hours trying to familiarize myself with the new system and finally gave up. I took the iMac back and asked them to re-install Snow Leopard. There were problems and instead of 2 hours, it took 2 days. Then I developed a bad case of sinusitis which laid me up for several days and now, here I am.
O Scale Trains is right. I am not a camera guy, at least not now. Forty years ago, I purchased a Nikon with a f1.4 lens and a telephoto lens. I shot many rolls of film and was a pretty decent photographer. But now, I consider myself a newbie. My first choice was the Nikon D7100 but it didn't fit my wife's hands. This was to be a family camera so there were some considerations to be observed. After much discussion with the clerk at a good camera shop, we decided on a Nikon Coolpix P610. The clerk was quite knowledgeable and demonstrated the camera. It can focus down to 6", maybe a bit less and then a 60X zoom, also. A nice combination and compromise.
Thanks again,
Ed Kelly
