Review – Sony DSLR A550

Sony DSLR A550

Sony DSLR A550

Sony announces the Alpha DSLR-A500 and DSLR-A550 this morning sporting the latest generation of CMOS sensors. Coupled with their BIONZ image processor, the A500 and A550 are optimized for low-light performance and boast a range of up to 12800 ISO.

The Alpha A500 weighs in with a 12.3 megapixel CMOS sensor and the Alpha A550 with 14.2 megapixels. Their differentiated model numbers also denote a difference in LCD resolution. The A500 features a 3.0 inch 230k monitor and the A550 features a higher-res 921k Xtra Fine LCD of the same physical size. The LCDs of both models will Tilt up or down at angles of 90 degrees.

Sony’s approach to the DSLR market has been an interesting one to watch – the first generation of the A2XX/3XX family was a three-camera assault on a market that most manufacturers had tried to address with a single model. Sony instead created three cameras that placed greater emphasis on attracting new users across from compact cameras (whether that be through price or what was, at the time, the most seamless, compact-like live view system on the market), rather than simply stripping down their higher-end models. With the recent refresh of that range, its cameras have moved even further towards a compact-user friendly interpretation of what an entry-level offering should look like – with the predictable result that the A230, A330 and A380 have prompted disappointment and even derision from the company’s DSLR fanbase.

However, the launch of the A500 and A550 make it clear not only that Sony wasn’t aiming for existing DSLR users with its 2XX / 3XX series but also that it intends to break the entry level market down into more segments than any other manufacturer has before tried. So now, in the sub $900 market, Sony offers five DSLRs – the price conscious A230, the simplified A330 and A380 live view cameras and the A500 /A550 for the more experienced DSLR user.

As such the A5XX series cameras regain a couple of the features lost from the most recent 2 and 3-series models – so the ‘fives’ feature the larger 11.8Wh FM500H batteries used in previous Alphas and include Auto Exposure Lock buttons. There is also a wider selection of external buttons for giving fast access to a variety of shooting settings such as drive mode, ISO and D-Range, freeing up the four-way controller for AF-point selection.
The return of two-mode live view

The most notable feature of the new cameras, however, is the inclusion of a second live view mode – so the A500 and A550 still sport a small secondary sensor in their viewfinders to provide live view with fast phase-detection AF, but can also utilize the slower but higher-resolution main-sensor live view system used by all other manufacturers. This two-mode solution is one we’ve not seen since the Olympus E-330 which, at the time, prompted the suggestion that live view was a problem looking for a solution. Since then, live view has become a highly prevalent feature but still one whose purpose isn’t always clear. Interestingly, Sony offers a little guidance, dubbing its new imaging sensor live view mode ‘Manual Focus Check Live View.

The other changes are also quite striking – the 3.0 inch LCDs (in a lovely high resolution incarnation on the A550), are better articulated than on the A330 and A380 and both 5-series cameras are based around CMOS, rather than the CCD technology of the 330 and 380.
Key features

The A550 and A500 represent a new category of camera for Sony and the specification makes it look like the company is aiming fairly squarely for Canon’s 500D and Nikon’s D5000, pitching a little above both in terms of most specifications.

* 12.3 and 14.2 mp CMOS Exmor sensors
* Manual Focus Check Live View using the main imaging sensor
* 5fps in optical viewfinder mode (7fps with focus and exposure locked on A550)
* New user interface
* HDR mode that combines multiple exposures
* 5-level manually selectable Dynamic Range Optimization
* Screen articulates up or down by 90 degrees
* Increased battery life (1,000 shots when using the viewfinder on the A500

Sadly, the much asked-for depth-of-field preview and mirror lock-up options have not returned. In both live view modes, the lens aperture is kept wide-open until the shot is taken, giving no representation of depth-of-field. And, although the mirror could theoretically be kept in the ‘up’ position, the new MF Check live view system still flips the mirror down and up again just as the shot is being taken, even when combined with self-timer. Whether this lack of mirror lock-up will make any difference to images won’t become apparent until we’ve tested the camera.

Pricing and availability
Look for the Sony Alpha DSLR-A500 and Sony Alpha DSLR-A550 in retail stores starting October. The A500 will start at $750 body only or $850 with 18-55mm kit lens. The A550 starts at $950 and will be available with the same lens for $1050.
