Canon SX620 vs Sony NEX-3N
The Canon PowerShot SX620 HS and the Sony Alpha NEX-3N are two digital cameras that were announced, respectively, in May 2016 and February 2013. The SX620 is a fixed lens compact, while the NEX-3N is a mirrorless interchangeable lens camera. The cameras are based on a 1/2.3-inch (SX620) and an APS-C (NEX-3N) sensor. The Canon has a resolution of 20.2 megapixels, whereas the Sony provides 16 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX620 HS and the Sony Alpha NEX-3N? 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.
The physical size and weight of the Canon SX620 and the Sony NEX-3N 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 size dimensions are rounded to the nearest millimeter.
The SX620 can be obtained in three different colors (black, silver, red), while the NEX-3N is available in two color-versions (black, white).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony NEX-3N is notably larger (23 percent) than the Canon SX620. In this context, it is worth noting that neither the SX620 nor the NEX-3N are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX620 has a lens built in, whereas the NEX-3N 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 NEX-3N and their specifications in the Sony E-Mount Lens Catalog.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 SX620 was launched at a lower price than the NEX-3N, despite having a lens built in. 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.
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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon SX620 features a 1/2.3-inch sensor and the Sony NEX-3N an APS-C sensor. The sensor area in the NEX-3N is 1204 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.5. The sensor in the SX620 has a native 4:3 aspect ratio, while the one in the NEX-3N offers a 3:2 aspect.
Despite having a smaller sensor, the Canon SX620 offers a higher resolution of 20.2 megapixels, compared with 16 MP of the Sony NEX-3N. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.18μm versus 4.78μm for the NEX-3N). However, it should be noted that the SX620 is much more recent (by 3 years and 2 months) than the NEX-3N, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the SX620 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon SX620 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX620 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Sony NEX-3N 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 Canon PowerShot SX620 HS has a native sensitivity range from ISO 80 to ISO 3200. The corresponding ISO settings for the Sony Alpha NEX-3N are ISO 200 to ISO 16000 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the NEX-3N provides a faster frame rate than the SX620. It can shoot movie footage at 1080/60i, while the Canon is limited to 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The SX620 and the NEX-3N are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. That said, the NEX-3N can be equipped with an optional viewfinder – the FDA-SV1. The adjacent table lists some of the other core features of the Canon SX620 and Sony NEX-3N along with similar information for a selection of comparators.

The SX620 writes its imaging data to SDXC cards, while the NEX-3N uses SDXC or Memory Stick PRO Duo cards.
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 Canon PowerShot SX620 HS and Sony Alpha NEX-3N and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX620 offers wifi support, while the NEX-3N does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
The SX620 is a recent model that features in the current product line-up of Canon. In contrast, the NEX-3N has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the NEX-3N was succeeded by the Sony A5000. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Sony websites.
So what is the bottom line? Is the Canon SX620 better than the Sony NEX-3N or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon PowerShot SX620 HS:
- More detail: Offers more megapixels (20.2 vs 16MP) with a 10% higher linear resolution.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- More detailed LCD: Has a higher resolution rear screen (922k vs 460k dots).
- Ready to shoot: Has a lens built-in, whereas the NEX-3N requires a separate lens.
- More compact: Is smaller (97x57mm vs 110x62mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the NEX-3N).
- Sharper images: Has hand-shake reducing image stabilization built-in.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.

- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Reflects 3 years and 2 months of technical progress since the NEX-3N launch.
Arguments in favor of the Sony Alpha NEX-3N:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
- Richer colors: The pixel size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
- Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
- More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- Faster burst: Shoots at higher frequency (4 vs 2.5 flaps/sec) to capture the decisive moment.
- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- Longer lasting: Gets more shots (480 versus 295) out of a single battery charge.
- More heavily discounted: Has been around for much longer (launched in February 2013).
If the count of individual advantages (bullet points above) is taken as a guide, the NEX-3N emerges as the winner of the match-up (14 : 11 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 Canon SX620 and the Sony NEX-3N place the cameras among the top in their class? Find out in the latest Best Superzoom 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 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 SX620 and the NEX-3N in practical situations. 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 hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], 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.

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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
