Rugged, magnesium-alloy body for reliability and durability
The bodies of the α900 and α700 reflect the same high quality and attention to detail as the images it delivers. Ruggedly constructed for years of dependable service, it features a front, back, and top made of strong, durable magnesium alloy, an interior chassis made of high-tensile aluminum, and a mirror box made of high-rigidity polycarbonate resin reinforced with carbon fibers. Balance and handling are superb, and the design and finish of the exceptionally easy-to-hold grip reflect Sony's long experience in developing broadcast-use video cameras and camcorders.
Anti-dust sensor protection for cleaner images
To protect the camera's sensor from dust contamination that can occur when changing lenses, an anti-dust mechanism vibrates the sensor at high speed every time the camera is switched off. In addition, the low-pass filter in front of the sensor is protected by a special anti-static coating to help prevent dust adherence.
High-endurance shutter unit for trouble-free shooting
Long-term reliability is also assured by a high-precision shutter unit that offers outstanding durability under heavy use. With a standalone unit service life of 100,000 shutter release cycles (approx.), it's built to withstand the performance demands of 1/8000 sec. shutter speeds and 5 fps continuous shooting with a 35mm full-frame sensor.
Dust and moisture protection for worry-free outdoor shooting
To allow worry-free shooting in adverse environmental conditions,* the α900's controls, terminals, view-finder, and other sensitive components are protected from dust and moisture by rubber seals. * Not waterproof or splashproof.
