Pat, the article states the second place camera is the SX 40. We have one. A friend, we bird with, takes pictures every day and sends them in an e-mail has one. He just upgraded to the SX50 and says it is a much better camera.
He is a retired optical engineer who took up digiscoping as a hobby. Photographing birds became his main endeavor. We have known him for about 8 years. We started with a Panasonic FZ10 with a 1.7 teleconverter. It was about 700 mm.
He was digiscoping with a minimum of 2000 mm for perching birds. He held the same camera behind his 7 X binoculars, about 700 mm, for flying birds. After seeing the pictures he was taking, we baught a scope and he helped us learn to digiscope.
We bought several Panasonic over the years. Mike had a couple along with other manufactures' super-zoom cameras. He had a FZ28 before he bought a SX 30, the SX 40 and now the SX50.
Mike takes pictures rain or shine. We live near Seattle. This time of year we are really light challenged as you know. Image quality is his main concern but focusing in low light is a close second. He says that is much better with the SX50.
Mike has a web site that he updates every Saturday with that week's pictures. This is not a best of, it is the best of the variety of birds from each day. You can view this week here;http://www.mikehamilton.biz/
At the top of the page he explains his equipment. Sometimes he will tell which camera he is using for each shot. This week he has not. Most of the pictures of Eagles and hawks are more than likely through the scope because of distance. All flying birds and landscapes will be with the SX50. Small birds could be either way.
We usually meet him weekly at Black River. The heron and most of the waterfowl are more than likely digiscoped because they are on the far shore.
Hope this is of help, BnB
