Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha SLT-A58 and the Sony Alpha SLT-A68? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

An illustration of the physical size and weight of the Sony A58 and the Sony A68 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.

Size Sony A58 vs Sony A68
Compare A58 versus A68 top
Comparison A58 or A68 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A68 is notably larger (21 percent) than the Sony A58. Moreover, the A68 is markedly heavier (24 percent) than the A58. In this context, it is worth noting that neither the A58 nor the A68 are weather-sealed.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The A58 was launched at a somewhat lower price (by 14 percent) than the A68, which makes it more attractive for photographers on a tight budget. 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

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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an APS-C sensor and have a format factor (sometimes also referred to as "crop factor") of 1.5. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the A68 uses a more advanced image processing engine (BIONZ X) than the A58 (BIONZ), with benefits for noise reduction, color accuracy, and processing speed.

Sony A58 and Sony A68 sensor measures

While the two cameras under review share the same sensor size, the A68 offers a higher resolution of 24 megapixels, compared with 19.8 MP of the A58. This megapixels advantage translates into a 10 percent gain in linear resolution. On the other hand, these sensor specs imply that the A68 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.91μm versus 4.31μm for the A58). However, it should be noted that the A68 is much more recent (by 2 years and 8 months) than the A58, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

The resolution advantage of the Sony A68 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A68 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Sony A58 are 27.3 x 18.2 inches or 69.3 x 46.1 cm for good quality, 21.8 x 14.5 inches or 55.4 x 36.9 cm for very good quality, and 18.2 x 12.1 inches or 46.2 x 30.8 cm for excellent quality prints.

The Sony Alpha SLT-A58 has a native sensitivity range from ISO 100 to ISO 16000, which can be extended to ISO 100-25600. The corresponding ISO settings for the Sony Alpha SLT-A68 are ISO 100 to ISO 25600 (no boost).

A58 versus A68 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under consideration, the A68 has a markedly higher DXO score than the A58 (overall score 5 points higher), which will translate into better image quality. The advantage is based on 0.8 bits higher color depth, 1 EV in additional dynamic range, and 0.1 stops of reduced low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Note: DXO values in italics represent estimates based on sensor size and age.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60i).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The A58 and the A68 are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 1440k dots. The adjacent table lists some of the other core features of the Sony A58 and Sony A68 along with similar information for a selection of comparators.

One feature that is present on the A68, but is missing on the A58 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

Concerning the storage of imaging data, both the A58 and the A68 write their files to SDXC or Memory Stick PRO Duo cards. The A68 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the A58 cannot take advantage of Ultra High Speed SD cards.

Connectivity comparison

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-A58 and Sony Alpha SLT-A68 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the A58 and the A68 have been discontinued, but can regularly be found used on eBay. The A58 was replaced by the Sony A68, while the A68 does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Sony website.

Review summary

So how do things add up? Which of the two cameras – the Sony A58 or the Sony A68 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Sony Alpha SLT-A58:

  • More compact: Is smaller (129x95mm vs 143x104mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 118g or 19 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (690 versus 540) on a single battery charge.
  • More affordable: Was introduced into a lower priced segment (14 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in February 2013).


Advantages of the Sony Alpha SLT-A68:

  • More detail: Has more megapixels (24 vs 19.8MP), which boosts linear resolution by 10%.
  • Better image quality: Scores markedly higher (5 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (1 EV of extra DR).
  • Better jpgs: Has a more modern image processing engine (BIONZ X vs BIONZ).
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Faster burst: Shoots at higher frequency (8 vs 5 flaps/sec) to capture the decisive moment.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Reflects 2 years and 8 months of technical progress since the A58 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the A68 emerges as the winner of the match-up (8 : 5 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

A58 05:08 A68

How about other alternatives? Do the specifications of the Sony A58 and the Sony A68 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the A58 and the A68 in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
