Panasonic LX100 versus Panasonic TZ100

The Panasonic Lumix DMC-LX100 and the Panasonic Lumix DMC-TZ100 (labelled Panasonic ZS100 in some countries) are two digital cameras that were officially introduced, respectively, in September 2014 and January 2016. Both the LX100 and the TZ100 are fixed lens compact cameras that are based on a Four Thirds (LX100) and an one-inch (TZ100) sensor. The LX100 has a resolution of 12.7 megapixel, whereas the TZ100 provides 20 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Panasonic LX100 vs Panasonic TZ100

The physical size and weight of the Panasonic LX100 and the Panasonic TZ100 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the LX100 – represents 100 percent across all the size and weight measures).

The camera’s price is obviously a critical decision-making factor. 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 somewhat lower price (by 22 percent) than the LX100, which makes it more attractive for photographers on a tight budget. 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: Panasonic LX100 vs Panasonic TZ100

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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic LX100 features a Four Thirds sensor and the Panasonic TZ100 an one-inch sensor. The sensor area in the TZ100 is 48 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 2.75. The sensor in the LX100 has a native 4:3 aspect ratio, while the one in the TZ100 offers a 3:2 aspect.

Panasonic LX100 and Panasonic TZ100 sensor measures

Despite having a smaller sensor, the TZ100 offers a higher resolution of 20 megapixel, compared with 12.7 MP of the LX100. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 4.21μm for the LX100). However, it should be noted that the TZ100 is a somewhat more recent model (by 1 year and 3 months) than the LX100, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.

LX100 versus TZ100 MP

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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (4K/30p).

 

Feature comparison: Panasonic LX100 vs Panasonic TZ100

Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the LX100 offers a substantially higher resolution than the one in the TZ100 (2764k vs 1166k dots). The following table reports on some other key feature differences and similarities of the Panasonic LX100, the Panasonic TZ100, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The TZ100 has a touchscreen, while the LX100 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, both cameras feature an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the LX100 and the TZ100 have zoom lenses build in. The LX100 has a 24-75mm f/1.7-2.8 optic and the TZ100 offers a 25-250mm f/2.8-5.9 (focal lengths in full frame equivalent terms). Hence, the LX100 provides a wider angle of view at the short end than the TZ100, but less tele-photo reach at the long end. The LX100 offers the faster maximum aperture.

Both the LX100 and the TZ100 write their imaging data to SDXC cards.

The LX100 is a current model that online retailers, such as amazon, will have in stock. In contrast, the TZ100 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the TZ100 was succeeded by the Panasonic TZ200.

Review summary: Panasonic LX100 vs Panasonic TZ100

So what is the bottom line? Is the Panasonic LX100 better than the Panasonic TZ100 or vice versa? The listing below highlights the relative strengths of the two models.


Arguments in favor of the Panasonic Lumix DMC-LX100:

  • More detailed viewfinder: Has higher resolution electronic viewfinder (2764k vs 1166k dots).
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • Better light gathering: Has a lens with a wider maximum aperture (f/1.7 vs f/2.8).
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More heavily discounted: Has been on the market for longer (launched in September 2014).


Reasons to prefer the Panasonic Lumix DMC-TZ100:

  • More detail: Has more megapixels (20 vs 12.7MP), which boosts linear resolution by 28%.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • Less heavy: Has a lower weight (by 81g or 21 percent) and is thus easier to take along.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was released into a lower priced segment (22 percent cheaper at launch).
  • More modern: Was introduced somewhat (1 year and 3 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the TZ100 comes out slightly ahead of the LX100 (8 : 7 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.

LX100 07:08 TZ100

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the LX100 and the TZ100 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 following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted with care, 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
