Howdy all, I have been into photography for a few years now, shooting mostly with my K100d and have been looking as of late to "Upgrade" to a new camera. To give you some background on what I shoot, it varies from Pics of my dogs in the backyard, to portrait shots up in hunt camp to long range wildlife. I also volunteer to take pics at some motor sports events. So its a pretty wide range that I am doing. So here it is, I have narrowed it down to three options, Canon 50D Nikon D90 Nikon D300 I know they all have their ups and downs, but what I am looking for here is your opinions on WHICH you think is better, and WHY you think its better. Thanks Guys and Gals.
