I chose not to reward Nikon's marketing strategy by not buying a newer camera from Nikon, but gave my money to Keh camera. I purchased a used Nikon D300s with a larger buffer, better AF module and not crippled like the D 600 or D 7100 cameras. I took a picture of the sky at f/22 and looked on my 25 inch computer monitor and only found two small dust spots. The camera already had about 67,000 shutter actuations out of an estimated 150,000 life. I figure that I may add another 10,000 actuations in the next 6 or 8 years at which point I may buy a used D 400. I paid just under $ 900 for this used D 300s and have been amazed at how much more capable it is than my D 80 that I have had for about 5 years.
