Even the lower end of the specified range of effectiveness means a pretty significant improvement in one's ability to hand-hold long exposures. A 3.5-stop improvement would mean you could shoot as slow as 1/11 second and get the same results (blur-wise) as when shooting at 1/120 second unaided. Translating that into real-world shutter speeds, a two-stop improvement means that a shutter speed of 1/30 second would give you the same resistance to blur from camera shake that a speed of 1/120 would without anti-shake. Sony claims that the Super SteadyShot anti-shake system in the A350 provides a 2.5 to 3.5-stop reduction in the blurring produced by camera shake. (Theoretically, a faster CPU could let the system respond to and compensate for higher-frequency vibrations.) This body-based anti-shake approach is based on technology Sony acquired from Konica Minolta, but Sony claims that a more powerful processor in the A350 increases the system's effectiveness beyond that of similar systems in previous Konica Minolta SLR models. The Sony A350 also employs Sony's Super SteadyShot anti-shake technology, which uses a highly sensitive angular rotation sensor and Smooth Impact Drive Mechanism (SIDM) to move the CCD assembly itself to counteract camera movement, rather than the more common approach of moving an optical element inside the lens. (But don't forget to switch back to AF mode for the rest of your shooting!) Sony A350 Anti-Shake Stow the flash head, and then take your picture. Then switch the focus mode to manual focus, being careful not to touch the focus ring on the lens. (Although its low-light focusing ability is much better than average.) If the camera is fixed on a tripod, you can work around this limitation, but it's somewhat awkward: With the flash head up, half-press the shutter button to make the camera focus. This is a real limitation for available-light photography, as the camera can expose at light levels below those it can focus at. This has the advantage that the light from the flash is very bright, but the downside is that you can only get AF assist when the flash head is raised. The Sony A350 uses its built-in flash head as a very bright AF-assist light for better focusing in dim lighting. The active AF area is briefly illuminated in the viewfinder. The Local setting is Sony's terminology for a manual AF area selection, and lets you manually set the main AF point by using the Multi-controller to highlight one of the nine AF points. Spot mode bases its focus on the very center of the frame, where the square target resides. Wide AF bases its focus on the most prominent subject detail in the portion of the image that falls within the AF brackets. You can override the chosen AF mode by pressing the Spot AF / OK button in the center of the Multi-controller, which defaults to the more accurate center AF point (the latter indicated by a target box in the center of the viewfinder). The default option is a nine-point Wide Focus area, indicated by an array of dashes inset within four widely-spaced brackets in the viewfinder image. The Automatic setting will lock focus on a still subject or continually adjust focus on a moving subject, for as long as the Shutter button is halfway pressed.Īutofocus Area also has three options available through the Function menu: Wide, Spot, and Local (manual setting). Single-shot sets focus with each half-press of the Shutter button, while Continuous mode is constantly adjusts the focus whether the Shutter button is pressed or not. The Autofocus Mode option under the Function menu offers Single-shot AF, Automatic AF and Continuous AF settings. The Function button provides access to additional AF Area and focus mode options. You can select between Auto and Manual focus modes. The Sony A350 provides both manual and automatic focus control modes, set by the Focus Mode switch on the left side of the camera. (Thus, a 50mm lens will provide about the same view as a 75mm lens on a 35mm camera.) To find the approximate 35mm equivalent focal length, multiply the focal length of the lens by 1.5. The Sony A350's CCD is smaller than a 35mm frame, so the angle of view at any given focal length will not be the same as on a 35mm camera. A small button on the front of the camera releases the lens from its mount, so it can be turned and removed. The Sony A350 is sold body-only, but there are two kits, one that comes with a Sony 18-70mm f/3.5 kit lens, and another that comes with both the 18-70 and a 55-200mm f/4-5.6 telephoto zoom lens. The Sony A350 features a bayonet lens mount, which accommodates a range of Sony and Konica Minolta lenses. The Sony A350's Alpha lens mount is compatible with the full array of Alpha lenses, both screw-drive and electronic autofocus models.
