The D300s has a DX-format CMOS Image Sensor which means that the lens focal length is subject to the FX/DX 1.5x crop factor. On DX format cameras, the AF-S Zoom-Nikkor 17-35mm f/2.8D IF-ED has a focal length equivalent to 25.5-52.5mm on an FX format camera.
The lens aperture is not affected. For more information on DX vs. FX please see: http://www.nikonusa.com/en/Learn-An...
Please see the lens simulator for examples of DX/FX: http://static.nikonusa.com/Lens-Sim...
