The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Sony A68 was launched in the US market at a price of $699. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison with a 35mm slide
The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.
The Sony A68 features an APS-C sensor and has a format factor (sometimes also referred to as "crop factor") of 1.5. Within the spectrum of camera sensors, this places the Sony A68 among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.
For most cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The A68 indeed provides movie recording capabilities. The highest resolution format that the A68 can use is 1080/60i.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A68 has an electronic viewfinder with a resolution of 1440k dots. The viewfinder offers a field of view of 100% and a magnification of 0.57x. The following tables report on some other key feature differences and similarities of the Sony A68 and comparable cameras.

One convenient feature of the A68 is the presence of an on-board flash. While this built-in flash is not very powerful, it can at times be useful as a fill-in light to brighten deep shadow areas.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Sony Alpha SLT-A68 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A68 has a microphone port. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
While the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the A68. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is why expert reviews are important. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
Sony A68 FAQ
Below are some additional questions and answers concerning some particular features of the A68.
What technology is the imaging sensor in the A68 based on?
The camera is build around a CMOS (Complementary Metal–Oxide–Semiconductor) sensor.
Which image processing chip is used to convert the raw signal into an image file and perform noise reduction and image sharpening?
Sony equipped the A68 with the BIONZ X image processor.
What is the ISO sensitivity range of the A68?
The camera has a native sensitivity range from ISO 100 to ISO 25600.
What is the life expectancy of the shutter in the Sony Alpha SLT-A68?
Sony mentions a shutter rating of 100 000 actuations for the A68. This number represents a Mean Time before Failure, that is an average value. The shutter might fail earlier, or it might last longer. Anyway, in order to exhaust the expected shutter life of the A68 over, say, three years, one would have to take about 100 pictures each and every day.
Is it difficult to use manual focus lenses with the Sony A68?
The A68 offers focus peaking as a manual focus aid. This feature works by placing a colored highlight on in-focus zones within the image.
Does the Sony A68 feature an autofocus assist light?
Yes, the camera has a lamp built-in that can illuminate the subject and improve autofocus in low-light settings.
What is the fastest shutter speed that can be used with flash?
The A68's flash sync speed is 1/160 sec.
Does the Sony A68 support the Ultra High Speed (UHS) bus interface for SD cards?
Yes, the camera can indeed use UHS-I cards (data transfer speed of up to 104 MB/s).
Which battery does the A68 use?
The camera gets its power from the NP-FM500H (here at amazon), which is a rechargeable Lithium-Ion power pack.
Is there a vertical grip available for the A68?
Sony does not offer an optional battery grip, but third party suppliers do (see here on eBay).
