Dude!! Great choice for a camera body. D300 is an excellent pro body camera, but very long in the tooth at this point, so moving up to something more current opens up a lot of capability for you, and not just in pixels. Congratulations!Bought my own gift. Needed a higher megapixel camera for my bee work. Old D-300 just wasn't making it. Been saving up my credit card points for 20 years or so. Points payed for it. D-810. OMG, the resolution is blowing me away. Fun!
