Anything I take is for the web so I don't worry too much about how many megazillion pixels it is. I run an old D50 Nikon that has the motor drive in the body - that way I have far more lenses to chose from. Just bought a Sigma 150-500 that I will play around with and see how I like the longer lens. Have been using a 300 fixed for years but want just a little more reach.
I look at cameras for moto photography as needing to be reasonably inexpensive as over the years I have had a couple fail and both times the photo shop reported to the insurance company that as they had dust in places there should not be dust it must be considered that they were not being used in an appropriate manner
