Panasonic ZS70 vs Sony NEX-3

The Panasonic Lumix DC-ZS70 (called Panasonic TZ90 in some regions) and the Sony Alpha NEX-3 are two digital cameras that were announced, respectively, in April 2017 and May 2010. The ZS70 is a fixed lens compact, while the NEX-3 is a mirrorless interchangeable lens camera. The cameras are based on a 1/2.3-inch (ZS70) and an APS-C (NEX-3) sensor. The Panasonic has a resolution of 20.2 megapixels, whereas the Sony provides 14 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

An illustration of the physical size and weight of the Panasonic ZS70 and the Sony NEX-3 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The ZS70 can be obtained in two different colors (black, silver), while the NEX-3 is available in three color-versions (black, silver, red).

Compare ZS70 versus NEX-3 top
Comparison ZS70 or NEX-3 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony NEX-3 is somewhat smaller (3 percent) than the Panasonic ZS70. In this context, it is worth noting that neither the ZS70 nor the NEX-3 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the ZS70 has a lens built in, whereas the NEX-3 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-3 and their specifications in the Sony E-Mount Lens Catalog.

Concerning battery life, the ZS70 gets 380 shots out of its Panasonic DMW-BLG10 battery, while the NEX-3 can take 330 images on a single charge of its Sony NP-FW50 power pack. The power pack in the ZS70 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

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

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The ZS70 was launched at a lower price than the NEX-3, 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.

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 Panasonic ZS70 features a 1/2.3-inch sensor and the Sony NEX-3 an APS-C sensor. The sensor area in the NEX-3 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 ZS70 has a native 4:3 aspect ratio, while the one in the NEX-3 offers a 3:2 aspect.

Panasonic ZS70 and Sony NEX-3 sensor measures

Despite having a smaller sensor, the Panasonic ZS70 offers a higher resolution of 20.2 megapixels, compared with 14 MP of the Sony NEX-3. 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 5.11μm for the NEX-3). However, it should be noted that the ZS70 is much more recent (by 6 years and 11 months) than the NEX-3, 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 ZS70 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Panasonic ZS70 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the ZS70 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-3 are 23 x 15.3 inches or 58.3 x 38.8 cm for good quality, 18.4 x 12.2 inches or 46.7 x 31 cm for very good quality, and 15.3 x 10.2 inches or 38.9 x 25.9 cm for excellent quality prints.

The Panasonic Lumix DC-ZS70 has a native sensitivity range from ISO 80 to ISO 3200, which can be extended to ISO 80-6400. The corresponding ISO settings for the Sony Alpha NEX-3 are ISO 200 to ISO 12800 (no boost).

In terms of underlying technology, the ZS70 is build around a BSI-CMOS sensor, while the NEX-3 uses a 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.

ZS70 versus NEX-3 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 consideration, the NEX-3 offers substantially better image quality than the ZS70 (overall score 32 points higher). The advantage is based on 3 bits higher color depth, 1.4 EV in additional dynamic range, and 3 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the ZS70 has an electronic viewfinder (1166k dots), which can be very helpful when shooting in bright sunlight. In contrast, the NEX-3 relies on live view and the rear LCD for framing. That said, the NEX-3 can be equipped with an optional viewfinder – the FDA-SV1. The table below summarizes some of the other core capabilities of the Panasonic ZS70 and Sony NEX-3 in connection with corresponding information for a sample of similar cameras.

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

One difference between the cameras concerns the presence of an on-board flash. The ZS70 has one, while the NEX-3 does not. While the built-in flash of the ZS70 is not very powerful, it can at times be useful as a fill-in light.

Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the ZS70 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The ZS70 writes its imaging data to SDXC cards, while the NEX-3 uses SDXC or Memory Stick PRO Duo cards. The ZS70 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the NEX-3 cannot take advantage of Ultra High Speed SD cards.

It is notable that the ZS70 offers wifi support, while the NEX-3 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the ZS70 and the NEX-3 have been discontinued, but can regularly be found used on ebay. The NEX-3 was replaced by the Sony NEX-3N, while the ZS70 was followed by the Panasonic ZS80. Further information on the features and operation of the ZS70 and NEX-3 can be found, respectively, in the Panasonic ZS70 Manual (free pdf) or the online Sony NEX-3 Manual.

Review summary

So how do things add up? Is the Panasonic ZS70 better than the Sony NEX-3 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the Panasonic Lumix DC-ZS70:

  • More detail: Offers more megapixels (20.2 vs 14MP) with a 17% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better video: Provides higher definition movie capture (4K/30p vs 720/30p).
  • Easier framing: Has an electronic viewfinder for image composition and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster burst: Shoots at higher frequency (10 vs 7 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Ready to shoot: Has a lens built-in, whereas the NEX-3 requires a separate lens.
  • Longer lasting: Can take more shots (380 versus 330) on a single battery charge.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • 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.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Reflects 6 years and 11 months of technical progress since the NEX-3 launch.

ilogo

Arguments in favor of the Sony Alpha NEX-3:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Scores substantially higher (32 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (3 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.4 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (3 stops ISO advantage).
  • Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • More heavily discounted: Has been around for much longer (launched in May 2010).

If the number of relative strengths (bullet points above) is taken as a guide, the ZS70 is the clear winner of the match-up (17 : 9 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

ZS70 17:09 NEX-3

How about other alternatives? Do the specifications of the Panasonic ZS70 and the Sony NEX-3 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the ZS70 and the NEX-3 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 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], 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.
