Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha A5100 and the Canon PowerShot G16? 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

The physical size and weight of the Sony A5100 and the Canon G16 are illustrated 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 dimensions are rounded to the nearest millimeter.

The A5100 can be obtained in two different colors (black, white), while the G16 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 Canon G16 is notably larger (20 percent) than the Sony A5100. In this context, it is worth noting that neither the A5100 nor the G16 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G16 has a lens built in, whereas the A5100 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the A5100 and their specifications in the Sony E-Mount Lens Catalog.

Concerning battery life, the A5100 gets 400 shots out of its Sony NP-FW50 battery, while the G16 can take 360 images on a single charge of its Canon NB-10L power pack. The power pack in the A5100 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

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

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. 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Sony A5100 features an APS-C sensor and the Canon G16 a 1/1.7-inch sensor. The sensor area in the G16 is 89 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 4.65. The sensor in the A5100 has a native 3:2 aspect ratio, while the one in the G16 offers a 4:3 aspect.

With 24MP, the A5100 offers a higher resolution than the G16 (12MP), but the A5100 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 1.87μm for the G16) due to its larger sensor. Moreover, the A5100 is a somewhat more recent model (by 11 months) than the G16, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Sony A5100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A5100 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 Canon G16 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The A5100 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Sony Alpha A5100 has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Canon PowerShot G16 are ISO 80 to ISO 12800 (no boost).

In terms of underlying technology, the A5100 is build around a CMOS sensor, while the G16 uses a BSI-CMOS imager. 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 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 review, the A5100 provides substantially higher image quality than the G16, with an overall score that is 26 points higher. This advantage is based on 2.8 bits higher color depth, 1 EV in additional dynamic range, and 2.6 stops in additional 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.

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, and both provide the same movie specifications (1080/60p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G16 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the A5100 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Sony A5100, the Canon G16, and comparable cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The A5100 has a touchscreen, while the G16 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Canon G16 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The A5100 writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the G16 uses SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

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 A5100 and Canon PowerShot G16 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G16 has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The A5100 does not feature such an accessory-socket.

Both the A5100 and the G16 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 and Canon. Further information on the features and operation of the A5100 and G16 can be found, respectively, in the Sony A5100 Manual (free pdf) or the online Canon G16 Manual.

Review summary

So how do things add up? Is the Sony A5100 better than the Canon G16 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Sony Alpha A5100:

• More detail: Offers more megapixels (24 vs 12MP) with a 44% higher linear resolution.
• Better image quality: Scores substantially higher (26 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (2.8 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (1 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (2.6 stops ISO advantage).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (6 vs 2.2 flaps/sec) to capture the decisive moment.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• More compact: Is smaller (110x63mm vs 109x76mm) and thus needs less room in the bag.
• Longer lasting: Can take more shots (400 versus 360) on a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More modern: Is somewhat more recent (announced 11 months after the G16).

Arguments in favor of the Canon PowerShot G16:

• Easier framing: Has an optical viewfinder for image composition and settings control.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Has an integrated lens, whereas the A5100 necessitates an extra lens.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been on the market for longer (launched in August 2013).

If the number of relative strengths (bullet points above) is taken as a guide, the A5100 is the clear winner of the match-up (16 : 6 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 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 A5100 and the Canon G16 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Travel-Zoom Camera listings 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the A5100 or the G16. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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.

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

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
