In normal conditions, LV brightness will show any degree of underexposure down to black, but is capped for overexposure probably to prevent damage to the CCD or screen. The longer exposure time given also reduces the frame rate (frequency) and causes lag and smear effects when recomposing shots in poor light levels.

In low light you get a grainy LV just like a noisy low-light camcorder image, in good light you get a cleaner image, but it does not matter whether you set ISO 100 or 3200. The LV CCD sensitivity is linked to the camera ISO setting and metering, though it actually appears to have a regular auto-gain function reflected in the quality of image.

It does not work with purely manual lenses however, and a test with T-mount bellows showed that auto gain then compensates over a wide range (you can get within two stops, but no more accurate). You can set manual exposures visually, without any reference to this scale, by judging the LV. It is a delight to set manual, and watch the small -2 to +2 exposure indicator hit zero at exactly the point where the viewing screen looks perfect. LV reflects both WB and +/- over-ride or manual exposure adjustments. One display mode for LV shows a small semi-transparent mono histogram in the lower left corner of the 2.7 inch screen, and a few tests proved that it does match a final JPEG histogram accurately enough to fine-tune exposure on screen. Although the video sensor is not the actual CCD used to take the picture, it offers a reasonable analysis of the scene. The other big benefits of LV are greatly improved exposure and white balance accuracy. You can still press the joypad to select centre spot focus or move the focus point round, depending on the AF mode used. The Live View adds to the focus-point highlighting of the finder screen an electronic overlay which identifies not just the main focus point, but all the sensors active during Wide Area focus. Because the image is just a video view of the focusing screen, the 9-point AF sensor as used for regular autofocus remains active. This, of course, is what Sony claims with multiple labels attached to new cameras proclaiming ‘Quick AF Live View’ as the unique selling point for this and the sister 10 megapixel Alpha 300. Overall, the operation of the Alpha 350 is slick and responsive and gives the impression of ‘real time’ without delays for the Live View image to build or react to light levels and white balance. These timings are all comparable to similar DSLRs, such as the Nikon D60 with its start-up time of 0.19 seconds and no Live View. The screen blacks out for just 0.1 seconds between the end of review, and the return of a Live View image the same delay occurs when you interrupt Live View by first pressure on the shutter release.
If you enable Review, there is a blackout delay of exactly one second before the image just shot appears on screen, and according to your preferences, it will be displayed for 2, 5 or 10 seconds. If you switch ‘Auto Review’ (chimping mode!) off, LV returns in under 0.2 seconds. Making the exposure blanks out the Live View because the mirror has lifted.

When you do switch on, a live viewfinder image appears in 0.2 seconds reaching full brightness at 0.25 seconds – by this time the camera has also checked its CF card, executed autofocus and exposure setting, and is ready to shoot if you already have your finger on the shutter. The Smart Teleconverter button (see later comments) is seen on the right hand extreme of the upper back, for thumb use. The LV/OVF switch has a very light action and is mechanical – it works when the camera is switched off. The A350 does not have to be switched on to make the change. The entire operation is purely mechanical and involves hardly any pressure on the small Live View/OVF switch next to the prism on the right hand top plate of the camera. At the same time, the lower front face of the mirror prism shifts its angle and position slightly this diverts the view of the focusing screen to a CCD and lens assembly positioned to the left of the eyepiece, via a 45° mirror prism placed above it. The difference between the Olympus method and Sony’s system is that no light is lost from the A350 optical finder, as a physical switch changes the lightpath instead, blocking off the viewfinder with a shutter. The shooting settings and EV scale remain present permanently. The standard default Live View image – by pressing DISPLAY when LV is active, the screen cycles from this to a display with a small histogram in the bottom left corner and no image settings information, then to one with no histogram or information at all on the image, then back. The Sony Alpha 350 14.2 megapixel DSLR pioneers a new type of Live View, related to Olympus’s original Mode A of the E-330 where a beamsplitting arrangement allowed a video CCD to view the actual focusing screen of the SLR system.
