has anyone owned a d300? I'm thinking and wondering if it's worth to getting one for $500 to try out Nikon. I've been using a d60 and love the files but the body is very limited.
was very close to getting it today off someone but it's too late to meet at this time.
D300 is a good sturdy camera, with the major advantage of what was then (D3, D700) Nikon's top end AF system. Image quality is generally good, low light performance is about 1 stop worse than D700. I think the body will be around the same size as your 50D, maybe just a bit bigger?
If camera size and top end AF are not so important, the Nikon D90 pretty much matches D300 for image quality and low-light performance, and adds one of Nikon's first attempts at DSLR video function - back in 2008/2009 we were using 2x D700, 1x D300, and 1x D90, but found ourselves only needing 3 camera bodies, and we sold the D300 but kept the D90.
Just before we switched to Nikon, we were using 2x 5D, 1x 1Dsmk1, 1x 40D.
