Panasonic TZ100 versus Sony RX10 II

The Panasonic Lumix DMC-TZ100 (called Panasonic ZS100 in some regions) and the Sony Cyber-shot DSC-RX10 II are two digital cameras that were revealed to the public, respectively, in January 2016 and June 2015. Both the TZ100 and the RX10 II are fixed lens compact cameras that are equipped with an one-inch sensor. Both cameras offer a resolution of 20 megapixel.

Body comparison

The physical size and weight of the Panasonic TZ100 and the Sony RX10 II are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the TZ100 – represents the basis for the calculations across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX10 II is considerably larger (57 percent) than the Panasonic TZ100. Moreover, the RX10 II is substantially heavier (161 percent) than the TZ100. It is noteworthy in this context that the RX10 II is splash and dust-proof, while the TZ100 does not feature any corresponding weather-sealing.

Concerning battery life, the TZ100 gets 300 shots out of its DMW-BLG10 battery, while the RX10 II can take 400 images on a single charge of its NP-FW50 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The TZ100 was launched at a markedly lower price (by 46 percent) than the RX10 II, which puts it into a different market segment. 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature an one-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 2.75. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sensor size

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 20 megapixel. This similarity in sensor specs implies that both the TZ100 and the RX10 II have the same pixel density, as well as the same pixel size. It should, however, be noted that the TZ100 is a somewhat more recent model (by 6 months) than the RX10 II, and its sensor might have benefitted from technological advances during this time.

Sensor resolution

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. 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, and both provide the same movie specifications (4K/30p).

Feature comparison

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 RX10 II 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 RX10 II, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the TZ100 and the RX10 II have zoom lenses build in. The TZ100 has a 25-250mm f/2.8-5.9 optic and the RX10 II offers a 24-200mm f/2.8-2.8 (focal lengths in full frame equivalent terms). Hence, the Sony provides a wider angle of view at the short end than the Panasonic, but less tele-photo reach at the long end. Both cameras offer the same maximum aperture.

Both the TZ100 and the RX10 II have been discontinued, but can regularly be found used on ebay. The RX10 II was replaced by the Sony RX10 III, while the TZ100 was followed by the Panasonic TZ200.

Summary

So how do things add up? Which of the two cameras – the Panasonic TZ100 or the Sony RX10 II – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.


logo checkmark

Arguments in favor of the Panasonic Lumix DMC-TZ100:

  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • More compact: Is smaller (111x65mm vs 129x88mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 501g or 62 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (46 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 6 months after the RX10 II).

logo checkmark

Reasons to prefer the Sony Cyber-shot DSC-RX10 II:

  • More detailed viewfinder: Has higher resolution electronic viewfinder (2359k vs 1166k dots).
  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (3200/sec vs 2000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (14 vs 10 flaps/sec) to capture the decisive moment.
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
  • Longer lasting: Gets more shots (400 versus 300) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More heavily discounted: Has been on the market for longer (launched in June 2015).

If the count of individual advantages (bullet points above) is taken as a guide, the RX10 II is the clear winner of the contest (10 : 6 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.

TZ100 06:10 RX10 II

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the TZ100 or the RX10 II. 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. This is where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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.
