Since it happens in the normal SLR pathway, the normal autofocus system is not interrupted as it is on Live View systems that use the main capture sensor, so there's no blackout, and autofocus is as fast as the system can produce regardless of the viewfinder mode. The beauty of the system is that the Sony A300 and A350 only use the secondary sensor to get a live image to the LCD, not for autofocus. (Other manufacturers have this as an optional separate step, which I think is a mistake, because it's too easy to forget to close the shutter.) Finally, it turns on the Live View sensor and the LCD to give you a real-world live image that's in-keeping with the spirit of the SLR. Second, the same motion closes a shutter inside the optical viewfinder to prevent stray light from entering and affecting either the Live View image or the exposure. First, it moves the mirror to reflect the light to the secondary sensor inside the pentamirror housing. Sliding that Live View switch forward does several things at once.

When compared to the Sony A100, the Sony A350 has a new ISO button, and the mode dial has moved to where the Function dial used to be. This switch engages the Live View mode and may even move the front element of the Pentamirror forward. This LCD also swivels out away from the body to tilt down or up for easier overhead or low-angle shooting.Įssentially identical to the Sony A200, the top deck of the Sony A300 and A350 have one unique feature: the Live View/OVF (Optical ViewFinder) switch.
Note the new battery indicator icon with the numerical percent-remaining display. The LCD is a little wider to match the 3:2 aspect ratio of the Sony A300 and A350's sensor. The button does nothing else in regular Record mode or Playback mode. Essentially, on the A350 it's cropping the image from a 14.2-megapixel image down to a 7.1-megapixel and 3.8-megapixel image, respectively without incurring the blur normally associated with digital zoom. According to Sony literature this gives the camera's 70mm kit lens the equivalent of a 200mm zoom. Active only in Live View mode, pressing this button first zooms the live view by approximately 1.4x, then to 2x. Anti-dust is also built in, with a static-free coating on the CCD's filter that is shaken each time the camera is powered off.Īnother new button on both the Sony A350 and A300 is the Smart Teleconverter 2x zoom button. Sony claims up to 3.5 stops of extra exposure with their body-based image stabilization system. Super SteadyShot stabilizes images with any lens mounted. Sony's new vertical battery grip (VG-B30AM) already announced for the Sony A200 also works with the new digital SLR cameras, duplicating many of the controls necessary for vertical shooting, and holds two InfoLITHIUM batteries, making all three cameras capable of shooting up to 1,500 shots.Įye-start Autofocus, also from the A100, starts up the autofocus system so the camera's ready before you even match your eye up to the viewfinder in most cases. It now reads "100%," in addition to displaying four bars to indicate battery status. The old battery icon has been augmented with a "percent remaining" indicator on the Sony A300 and A350. Like most other digital SLRs, the user deploys the flash with a button on the left side of the lens mount housing, by the big orange Alpha logo. Now these consumer cameras can deploy the flash in auto modes when necessary. The Sony A300 and A350 also have a new pop-up flash, rather than the old "pull-up" type. The same LCD-based function menu that appeared on the A200 earlier this year replaces the old dial-based function menu on the Sony A100, and many of the menu items and systems from the Sony A700 have made their way into the Sony A300 and A350. Shaped to better match the sensor's 3:2 aspect ratio, the Sony A200's 2.7-inch "Clear Photo" LCD has an anti-reflective coating for easy viewing in the sun, and 230,000 pixels, but the version on the A300 and A350 tilts up and down for easier viewing while shooting low or overhead. Autofocus in Live View is also as fast as it is in optical viewfinder mode, a major breakthrough among digital SLRs. Like the A200, Sony says that improvements to the A300 and A350's AF have made focus acquisition 1.7 times faster, thanks to the high-torque AF motor and improved AF sequence borrowed from the A700.
