Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha SLT-A68 and the Sony Alpha NEX-C3? 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 A68 and the Sony NEX-C3 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.

The NEX-C3 can be obtained in three different colors (black, silver, pink), while the A68 is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony NEX-C3 is considerably smaller (56 percent) than the Sony A68. Moreover, the NEX-C3 is substantially lighter (63 percent) than the A68. In this context, it is worth noting that neither the A68 nor the NEX-C3 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.

Concerning battery life, the A68 gets 540 shots out of its Sony NP-FM500H battery, while the NEX-C3 can take 400 images on a single charge of its Sony NP-FW50 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The NEX-C3 was launched at a somewhat lower price (by 14 percent) than the A68, which makes it more attractive for photographers on a tight budget. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the NEX-C3 is 1 percent smaller. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

In terms of chip-set technology, the A68 uses a more advanced image processing engine (BIONZ X) than the NEX-C3 (BIONZ), with benefits for noise reduction, color accuracy, and processing speed.

With 24MP, the A68 offers a higher resolution than the NEX-C3 (16MP), but the A68 has smaller individual pixels (pixel pitch of 3.91μm versus 4.78μm for the NEX-C3). However, the A68 is a much more recent model (by 4 years and 4 months) than the NEX-C3, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

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 NEX-C3 are 24.6 x 16.3 inches or 62.4 x 41.5 cm for good quality, 19.6 x 13.1 inches or 49.9 x 33.2 cm for very good quality, and 16.4 x 10.9 inches or 41.6 x 27.6 cm for excellent quality prints.

The Sony Alpha SLT-A68 has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Sony Alpha NEX-C3 are ISO 100 to ISO 12800 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

For many 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. Of the two cameras under review, the A68 has a notably higher overall DXO score than the NEX-C3 (overall score 6 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.4 bits higher color depth, 1.3 EV in additional dynamic range, and 0.6 stops of reduced low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A68 provides a higher video resolution than the NEX-C3. It can shoot video footage at 1080/60i, while the NEX-C3 is limited to 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A68 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the NEX-C3 relies on live view and the rear LCD for framing. That said, the NEX-C3 can be equipped with an optional viewfinder – the FDA-SV1. The table below summarizes some of the other core capabilities of the Sony A68 and Sony NEX-C3 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The A68 has one, while the NEX-C3 does not. While the built-in flash of the A68 is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the A68 and the NEX-C3 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 NEX-C3 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-A68 and Sony Alpha NEX-C3 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, which is missing on the NEX-C3. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Both the A68 and the NEX-C3 have been discontinued, but can regularly be found used on ebay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Sony. Further information on the features and operation of the A68 and NEX-C3 can be found, respectively, in the Sony A68 Manual (free pdf) or the online Sony NEX-C3 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Sony A68 or the Sony NEX-C3 – 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.

Reasons to prefer the Sony Alpha SLT-A68:

• More detail: Offers more megapixels (24 vs 16MP) with a 22% higher linear resolution.
• Better image quality: Scores markedly higher (6 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (1.4 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (1.3 EV of extra DR).
• Better jpgs: Has a more modern image processing engine (BIONZ X vs BIONZ).
• Better video: Provides higher definition movie capture (1080/60i vs 720/30p).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Faster burst: Shoots at higher frequency (8 vs 5.5 flaps/sec) to capture the decisive moment.
• Longer lasting: Can take more shots (540 versus 400) on a single battery charge.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 4 years and 4 months of technical progress since the NEX-C3 launch.

Advantages of the Sony Alpha NEX-C3:

• Better low-light sensitivity: Can shoot in dim conditions (0.6 stops ISO advantage).
• Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (920k vs 460k dots).
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• More compact: Is smaller (110x60mm vs 143x104mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 385g or 63 percent) and is thus easier to take along.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• More affordable: Was released into a lower priced segment (14 percent cheaper at launch).
• More heavily discounted: Has been around for much longer (launched in June 2011).

If the count of relative strengths (bullet points above) is taken as a measure, the A68 is the clear winner of the match-up (15 : 9 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Sony A68 and the Sony NEX-C3 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the A68 and the NEX-C3 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 why expert reviews are important. 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
