Nikon's D300 DX-format digital single-lens reflex camera is likely to appeal to novices and professionals alike. Advanced features start with the 12.3-megapixel image sensor, which produces natural-looking images with fine detail and sharp resolution. The 'picture control system' helps adjust images according to the user's requirements. The camera's magnesium-alloy chassis is lightweight but solid while the body features an enhanced sealing system to help protect against moisture and dust. This is Nikon's first D-SLR camera to have a self-cleaning sensor unit, which uses different resonance frequencies to shake particles free from the image sensor's filter. The Retouch Menu provides handy access to filter effects, trimming, red-eye correction, image overlay and other in-camera editing functions. The Nikon D300 costs HK$13,980.
