Burst shooting somewhat harder to use than would otherwise be the case. Instead, the A33 shows the previously captured image. The Continuous Advance Lo mode, which shoots at around 2. Image sensor and processor. Of course, the image sensor and processor are also an important part of the speed and image quality of the Sony A33. Zte axon 7 cheap The Sony SLT-A33 has a newly developed Exmor APS HD CMOS sensor, which has a total resolution of 14. It also includes the same on-chip analog and digital noise reduction that featured previously in the Sony A900. The Sony A33 also sports an updated BIONZ image processor, with reworked algorithms to allow its signature high-speed burst shooting, plus digital compositing and Full HD movie recording. The Sony Alpha A33 offers sensitivities ranging from ISO 100 to 12,800 equivalents, and can automatically select an ISO sensitivity between ISO 100 and 1,600 equivalents. The Sony A33 accepts Alpha-mount lenses from Sony, and is backward-compatible with older Minolta or Konica Minolta A-mount lenses, allowing use of a huge range of both current and historic glass. While Alpha-mount lenses can be used on NEX cameras through a mount adapter, they lose their in-body SteadyShot capabilities, whereas the Sony A33 retains this capability with the same lenses.

The drawback to using the pellicle mirror to provide a viewfinder as past cameras did is that with most of the light being transmitted to the imaging plane, the optical viewfinder is necessarily very dim. This directs the light path for the AF sensor not only upward, but also slightly forward, allowing optimal placement to keep body size to a minimum. When compared to standard LCD electronic viewfinders, ferroelectric types bring both advantages and disadvantages.

On the positive side, though, since each pixel provides full color, ferroelectric LCDs tend to look much smoother and more detailed than their traditional LCD siblings, with less obvious pixel structure. They also tend to have higher refresh rates, and indeed Sony specs the EVF used in the A33 as offering a 60Hz refresh rate. The slight distraction caused by the "rainbow" effect is relatively easy to ignore most of the time. Sony specs the EVF as having 1,440,000 dots, of which 1,152,000 are effective in the viewfinder display.

We believe that the company is following precedent here, by reporting a dot count as if each pixel constituted three separate color dots, rather than being time-multiplexed. This is likely done both to match the rear-panel LCD display aspect, and also because even with this crop, the EVF already has a generous 1. As noted previously, adopting a translucent mirror design has allowed Sony important benefits in terms of autofocus, burst shooting, and body size, and conceivably the removal of one more mechanical component could improve camera reliability, as well. Perhaps most significantly, light entering the lens is shared between the autofocus and image sensors at a fixed ratio. With a traditional SLR, all the incoming light arrives at the image sensor once the mirror is raised, and the same is true of an SLD camera whenever its shutter is open. With less light arriving at the sensor for an equivalent aperture, a translucent mirror camera must either lower its shutter speed, raise its sensitivity (and along with this, the levels of noise, or the amount processing to mitigate it), or some combination of both. An increase in sensor gain to compensate for the loss may explain why we see slightly higher noise levels from the A33 versus the A560, which share the same sensor.

While manual sensor cleaning will now be a familiar process for photographers used to shooting with a digital SLR, cleaning the pellicle mirror is a total unknown. The Sony A33 offers a selection of exposure modes commonplace on any DSLR, as well as several more unusual modes. Continuous Advance Priority AE increases the maximum burst shooting speed as compared to the standard Continuous Advance modes, but does so by requiring the aperture be fixed near its open position.

The Sony A33 uses the image sensor itself when metering, and considers the overall image as 1,200 separate zones in performing metering calculations. An autoexposure lock button is provided, allowing metering to be locked from a specific portion of the subject, then the overall image reframed as desired.

White balance options include auto, six presets (Daylight, Shade, Cloudy, Incandescent, Fluorescent, and Flash), plus both custom and direct color temperature (2,500 to 9,900K) options. The Sony A33 includes an auto-popup flash strobe with a guide number of 10 meters at ISO 100, as well as a proprietary flash hot shoe. The built-in flash has 18mm coverage, and a recycle time of four seconds.

Flash metering modes include ADI and pre-flash TTL. External strobes including the HVL-F36AM, HVL-F42AM, HVL-F56AM, and HVL-F58AM support high-speed sync and wireless shooting. The Sony A33 offers high definition interlaced video capture at up to 1,920 x 1,080 pixel resolution, commonly known as "Full HD" or "1080i. Using the non-standard 1,440 x 1,080 and standard definition VGA 640 x 480 pixel modes, progressive scan videos are created, matching the same actual sensor frame rates. Maximum video length is 29 minutes or two gigabytes per clip, whichever limit is reached first -- although if SteadyShot is enabled, this limit is slashed to just nine minutes per clip, likely due to sensor heating issues when using the sensor-shift stabilization mechanism.

Full HD videos are recorded using 17Mbps AVCHD compression, while the lower resolutions are saved with MP4 compression, at a bitrate of 12Mbps for 1,440 x 1,080 pixel video, or 3Mbps for VGA video. Movie capture is started and stopped with a dedicated Movie button located just to the right of the electronic viewfinder, within easy reach of a thumb press. The Sony A33 can continue to use phase detection autofocusing during movie recording, allowing swift adjustments to focus as your subject moves. Since standard Alpha-mount lenses are used, this focusing action is accompanied by significant levels of AF drive noise, which is clearly picked up by the camera in recorded videos. For consumers, this is likely a relatively small price to pay for sharply focused video, however, given that manually pulling focus during video capture is a difficult art to learn. However, if autofocus is used, lens aperture must be controlled automatically by the camera, regardless of AF servo mode. When using manual focus, the A33 allows manual control of aperture before video capture commences.

In all cases, shutter speed and ISO sensitivity of videos is controlled automatically. It can also accept external stereo microphones, courtesy of a 3. Alternatively, sound recording in videos can be disabled, if preferred.

Dust is reduced via a protective film (1) and shaken free by the sensor-shift mechanism (2). The Sony A33 has a dust abatement and removal system. A charge-protection coating on the low-pass filter aims to prevent dust adhering in the first place. The sensor shift mechanism used to provide SteadyShot image stabilization also doubles as a shake mechanism to try and free stubborn dust particles that settle on the low-pass filter, although at much lower frequencies than the vibration induced by cameras using a piezoelectric element.

From what we can tell, there is no strategy for keeping dust off the translucent mirror, except to blow the surface gently with air; it cannot be cleaned, and should never be touched. A fingerprint would require replacement at a service center.

The Sony A33 includes a dual-axis level gauge, which helps ensure level horizons and prevent converging verticals in photos. A clever way around it, though, is to set one viewer to the level gauge, and the other to a more informative display, since by default you can set the display modes independently.

The gauge is displayed in a style reminiscent of an aircraft attitude indicato
