The A700 is engineered to meet the needs of discerning photo enthusiasts who demand unfaltering performance. Tough, durable magnesium alloy body panels are complemented by a reinforced aluminium alloy chassis.
Weather-resistant silicon seals protect buttons and media card slots against dust and moisture. The precision high-speed shutter unit offers outstanding durability. Proven to approximately 100 000 cycles, it’s tough enough to cope with the challenging demands of serious photographers.
New Sensor: Exmor CMOS sensor
The all-new Sony-developed 12.2 effective megapixel “Exmor„ CMOS sensor delivers extraordinary levels of detailing with clear, lifelike colours.
A 3-layer optical low-pass filter on the sensor’s surface reduces moiré effects for even higher picture quality with smooth, natural textures.
For the first time, A/D conversion and initial noise reduction is performed on the sensor itself. This ensures that digitised signals are passed to the new-generation BIONZ processing engine with immunity from external noise.
Responsive, high speed autofocus is a ‘must have’ for anyone who’s serious about their photography.
With 11 focus points and 11 lines, the new double-cross sensor enhances AF performance under a wide range of real-world shooting conditions.
There’s also a powerful new AF drive motor that reduces noise and vibration while focusing, enhancing the ‘pro’ feel of the A700.
For macro shooting and other critical applications there’s a F2.8 AF sensor that doubles AF accuracy when used with wide-aperture lenses as bright as F2.8 or brighter while improving distance metering accuracy.
The AF illuminator assists with fast, accurate autofocus in low light or with low contrast subjects.The handy AF/MF button allows instant switchover between auto and manual focus modes.

Image above is 100% cropped of the photo’s focus area. Details seems to be slightly washed out and wordings are not as sharp. This may be due to handshake but a further processing should solve this issue easily.
The same image but USM and processed with Noise Ninja in Photoshop CS3. Wordings are clearer now. At ISO6400, this amount of noise is acceptable and until I get to hands on a D300, I would say that it is fairly usable.
Noise is visible at area that is not focused. F2.8 is used to capture this photo, handheld i assume. Color look a bit washed out once again.
I hope that the above sample and cropped images serves as your current guide for D300 ISO6400 comparison with other camera model. Only full review in the future when the camera is available can accurately justify the ISO performance of Nikon D300 and also D3.
