Panasonic TZ100 vs Sony NEX-7
The Panasonic Lumix DMC-TZ100 (called Panasonic ZS100 in some regions) and the Sony Alpha NEX-7 are two digital cameras that were officially introduced, respectively, in January 2016 and August 2011. The TZ100 is a fixed lens compact, while the NEX-7 is a mirrorless interchangeable lens camera. The cameras are based on an one-inch (TZ100) and an APS-C (NEX-7) sensor. The Panasonic has a resolution of 20 megapixels, whereas the Sony provides 24 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 Panasonic Lumix DMC-TZ100 and the Sony Alpha NEX-7? 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.
An illustration of the physical size and weight of the Panasonic TZ100 and the Sony NEX-7 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 dimensions are rounded to the nearest millimeter.
The TZ100 can be obtained in two different colors (black, silver), while the NEX-7 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-7 is notably larger (11 percent) than the Panasonic TZ100. In this context, it is worth noting that neither the TZ100 nor the NEX-7 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the TZ100 has a lens built in, whereas the NEX-7 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-7 and their specifications in the Sony E-Mount Lens Catalog.
Concerning battery life, the TZ100 gets 300 shots out of its DMW-BLG10 battery, while the NEX-7 can take 430 images on a single charge of its NP-FW50 power pack. The power pack in the TZ100 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

Any camera decision will naturally be influenced heavily by the price. 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 TZ100 was launched at a lower price than the NEX-7, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Panasonic TZ100 features an one-inch sensor and the Sony NEX-7 an APS-C sensor. The sensor area in the NEX-7 is 215 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 24MP, the NEX-7 offers a higher resolution than the TZ100 (20MP), but the NEX-7 nevertheless has larger individual pixels (pixel pitch of 3.90μm versus 2.41μm for the TZ100) due to its larger sensor. However, the TZ100 is a much more recent model (by 4 years and 4 months) than the NEX-7, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Sony NEX-7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NEX-7 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 Panasonic TZ100 are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.
The Panasonic Lumix DMC-TZ100 has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 80-25600. The corresponding ISO settings for the Sony Alpha NEX-7 are ISO 100 to ISO 16000 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the NEX-7 offers substantially better image quality than the TZ100 (overall score 11 points higher). The advantage is based on 1.3 bits higher color depth, 0.9 EV in additional dynamic range, and 0.9 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.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the TZ100 provides a higher video resolution than the NEX-7. It can shoot video footage at 4K/30p, while the Sony is limited to 1080/60i.
Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the NEX-7 offers a substantially higher resolution than the one in the TZ100 (2359k vs 1166k dots). The following table reports on some other key feature differences and similarities of the Panasonic TZ100, the Sony NEX-7, and comparable cameras.

|Sony RX100 IV||2359||n||3.0||1228||tilting||n||1/2000s||16.0||Y||Y|
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The TZ100 has a touchscreen, while the NEX-7 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
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 TZ100 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 Panasonic TZ100 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 TZ100 writes its imaging data to SDXC cards, while the NEX-7 uses SDXC or Memory Stick PRO Duo cards. The TZ100 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the NEX-7 cannot take advantage of Ultra High Speed SD 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 Panasonic Lumix DMC-TZ100 and Sony Alpha NEX-7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.
| WiFi |

It is notable that the TZ100 offers wifi support, while the NEX-7 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the TZ100 and the NEX-7 have been discontinued, but can regularly be found used on eBay. The TZ100 was replaced by the Panasonic TZ200, while the NEX-7 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 Panasonic and Sony websites.
So what is the bottom line? Is there a clear favorite between the Panasonic TZ100 and the Sony NEX-7? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

If the number of relative strengths (bullet points above) is taken as a guide, the NEX-7 emerges as the winner of the match-up (14 : 12 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 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.
How about other alternatives? Do the specifications of the Panasonic TZ100 and the Sony NEX-7 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the TZ100 or the NEX-7. 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 following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
