nikon d7000 and D300S?
looking to upgrade to another DX format camera, but not sure what to go to the new D7000 D300S or tried and tested. changes apart from the obvious features (more MP sensor, new, full high-definition video) doesn't not seem to be a big difference (apart from The D300S is heavier and faster 1fps) which has full HD doesn't really bother me, as a wildlife photographer I work alive and could do with the fps D300S extra that has to offer and D300S seems a bit more robust and made a bit more robust. As more MP in the D7000, I guess their hands, but rarely id want to print anything above A3 size. but that is the camera to go? (And Ive canon isn't a purchase option in Nikon brand and I'm not changing unless I touch the lottery, ha, ha) oh is worth mentioning that I'm just a little girl, so they carry a heavy camera around can be a problem and is lighter D7000 the 300
In laboratory tests, the D7000 comes in at number ten against the full-frame cameras. The D300 is excellent on the job number twenty-eight. These ratings are out of a field of 123 different cameras. If you look at the rating on this site, you will find that the D7000 the ranks of full-frame Canon 5D Mark II. That's pretty amazing, but when you look beyond its ranks over the H3DII Hassleblad sensor 50. http://dxomark.com/index.php/en/Camera-Sensor/Sensor-rankings As you can see, much has happened in the past five years since it became more technologically advanced dSLR
