I'm really beginning to regret going with Nikon these days, for two main reasons. One is that Canon's offerings in the form of the 40/50D are priced lower than the D300 while offering real world performance that's pretty close, and also because Canon lens selection is wider and also tends to be less expensive. I could deal with that if my D300 just worked as it was supposed to. Unfortunately, despite having already been back to Cameta/Nikon for servicing, I think they just put it in a circular file and returned it to me after a month, having done nothing to fix it. Just today, I was taking some sports pictures, and my lenses kept backfocusing and sometimes not even focusing at all in the actual image, despite the camera being focused in terms of what I saw through the viewfinder (i.e. person in focus in viewfinder, person out of focus on the display after the shot). I took several shots in a row of someone in the outfield that was standing completely still in bright sunlight (i.e. fast shutter speed) and the camera repeatedly gave me out of focus images. I couldn't post them even if I still had them because the subjects are minors, but I hope you can take my word for it. Other shots gave me similar results. I used both C and S focus modes, and fiddled around in general, but the results were always inconsistent at best. Frustratingly, sometimes my D300 works as it's supposed to. I feel like I'm good enough to know when it's me and when it's the camera, and I'm almost certain it's the camera, particularly as it's already been found in need of service once before by a professional and sent back to Nikon. At any rate, I love the D300 for what it can be, but I'm not too fond of my actual D300 these days. It has around 14,000 clicks on it now, and given that I can't actually be sure if it's in good technical condition, I don't even know if I could sell it. Anyone willing/able to talk me off a ledge here?
