Sony: Two live view Alpha-series DSLRs By
Michael R. Tomkins, The Imaging Resource
(Wednesday, January 30, 2008 - 15:01 EST)Sony has today announced two new single-lens reflex digital cameras that implement live view functionality.
The Sony Alpha DSLR-A350 and Sony Alpha DSLR-A300 are very closely related designs, sharing basically the same body which features a tilting 2.7" LCD display to take advantage of the live view mode. As you'd expect, the design also includes a Sony Alpha lens mount, and there's a CompactFlash Type-I or Type-II storage slot which is also compatible with Microdrives. Power comes from a proprietary NP-FM500H Lithium Ion rechargeable battery. Where the cameras differ is in their choice of image sensors (and of course, in their pricetags). The Sony Alpha A350 is the more expensive model and includes an APS-C sized 14.2 megapixel CCD image sensor. The Sony Alpha A300 meanwhile keeps the cost down just slightly with a 10.2 megapixel CCD image sensor which is also an APS-C type. One further difference most likely relates to the difference in imagers - with more data to throw around, the Sony A350 is limited to a burst rate of two frames per second, whereas the lower-res Sony A300 can manage a useful three frames per second.
The most interesting feature of both cameras is Sony's new Live View mode. Implemented in a manner reminiscent of early Olympus EVOLT digital SLRs, Sony has chosen to use a second sensor in the viewfinder's optical path, allowing the cameras' phase detection autofocus systems to function normally during live view mode. A tilting mirror in the viewfinder path directs light to either the optical viewfinder or the secondary live view image sensor. Sony has provided us with diagrams and some neat cutaways demonstrating this:

Sony Introduces Two Mainstream DSLR Cameras With Unique “Quick AF Live” View System
SAN DIEGO, Jan. 30, 2008 – Sony is bringing live-view shooting to its digital SLR camera line with today’s introduction of a 14.2-megapixel α (alpha) DSLR-A350 camera and 10.2-megapixel α (alpha) DSLR-A300 model. Both cameras feature new technologies that make picture taking faster, easier, and more familiar for first-time DSLR users.
Quick AF Live View System They both offer Sony’s new “Quick AF Live View” technology so you can frame photos on the camera’s LCD without sacrificing auto-focusing speed common to other live-view systems.
Sony’s innovative Pentamirror Tilt mechanism directs light to a dedicated live view image sensor, enabling fast and responsive TTL phase-detection auto-focusing, even during live view.
Eliminating the focus delay of other systems, the new models are equally responsive whether using live view or optical viewfinder.
With its two sensor design, Quick AF Live View can even continuously focus-track the subject and provide live view during burst shooting, helping you capture that special moment.
Taking further advantage of Quick AF Live View is the models’ variable angle 2.7-inch Clear Photo LCD ™ screen. This makes it easy to frame scenes from high or low positions difficult to reach when using an eye-level viewfinder.
With Live View and an adjustable LCD, the cameras do not need to be in front of the user’s face, allowing parents, for example, to maintain eye-contact when photographing their children.
“Mainstream users stepping up to DSLRs are looking for a similar experience to their point and shoot cameras, but without compromise in speed or performance” said Phil Lubell, director of marketing for digital cameras at Sony Electronics. “Quick AF Live View gives these new models a familiar shooting style without compromising speed – ideal for the growing market of first-time SLR users.”
Exceptional Image Quality The new models produce images with fine detail, rich tonality and vibrant color due to their APS-C CCD image sensors and BIONZ® processing engine. To aid shooting in low light, Super SteadyShot® image stabilization enables shutter speeds 2.5 to 3.5 steps slower than otherwise possible, with every compatible Minolta Maxxum® and Sony a (alpha) lens (sold separately) attached to the camera.
High sensitivity operation at ISO 1600 and 3200 and very low noise are made possible by the user-selectable high-ISO noise reduction features. Sony’s D-Range Optimizer delivers suitable tonality and exposures with rich shadow and highlight detail, even under high contrast situations.
Powerful Performance, Easy to Use The DSLR-A300 model can shoot about three continuous frames per second and the DSLR-A350 model can shoot up to two-and-a-half continuous frames per second, when using the optical viewfinder. Both are powered by the Bionz processing engine and supplied InfoLITHIUMTM battery for fast start-up times, quick response and long battery life – up to 730 shots per full charge when using the optical viewfinder and up to 410 shots per full charge in live-view mode.
Both models feature lighter, slimmer bodies for easy handling; an improved user interface; an automatic pop-up flash; a comfortable camera grip with an easily accessible mode dial; an anti-dust system to keep the CCD image sensor clean for spot-free pictures; and JPEG and RAW file format support. Both have a slot for CompactFlash™ Type I/II media cards.
An adaptor for Memory Stick Duo™ media cards is also available for the cameras and sold separately.
The new DSLR-A300 and DSLR-A350 cameras are compatible with a range of accessories, including the ergonomic Sony VG-B30AM vertical grip. Also available as an option is the new Sony HVL-F42AM flash unit. It offers advanced features such as automatic white balance adjustment with color temperature information, adjustable bounce angles, ADI metering and wireless remote operation to suit the needs of most photographers.
Price and Availability The DSLR-A300 kit with a DT 18-70mm f3.5-5.6 standard zoom lens will ship in April for about $800. The DSLR-A350 camera body will be available in March for about $800, and the DSLR-A350 kit with a DT 18-70mm f3.5-5.6 3.9x zoom lens will be available for about $900 at the same time. Both models will be available at sonystyle.com, Sony Style® retail stores (www.sonystyle.com/retail), military base exchanges, and authorized dealers nationwide. Pre-orders begin online today at www.sonystyle.com/dslr.
