Olympus E-420 vs Panasonic TZ100

The Olympus E-420 and the Panasonic Lumix DMC-TZ100 (labelled Panasonic ZS100 in some countries) are two digital cameras that were announced, respectively, in March 2008 and January 2016. The E-420 is a DSLR, while the TZ100 is a fixed lens compact. The cameras are based on a Four Thirds (E-420) and an one-inch (TZ100) sensor. The Olympus has a resolution of 10 megapixels, whereas the Panasonic provides 20 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 Olympus E-420 and the Panasonic Lumix DMC-TZ100? 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.

Body comparison

An illustration of the physical size and weight of the Olympus E-420 and the Panasonic TZ100 is provided 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.

The TZ100 can be obtained in two different colors (black, silver), while the E-420 is only available in black.

Compare E-420 versus TZ100 top
Comparison E-420 or TZ100 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic TZ100 is considerably smaller (39 percent) than the Olympus E-420. In this context, it is worth noting that neither the E-420 nor the TZ100 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 E-420 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 E-420 and their specifications in the Four Thirds Lens Catalog.

Concerning battery life, the E-420 gets 500 shots out of its BLS-1 battery, while the TZ100 can take 300 images on a single charge of its DMW-BLG10 power pack. The power pack in the TZ100 can be charged via the USB port, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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

Any camera decision will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. 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. 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 Olympus E-420 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 2.7. The sensor in the E-420 has a native 4:3 aspect ratio, while the one in the TZ100 offers a 3:2 aspect.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Olympus E-420 and Panasonic TZ100 sensor measures

Despite having a smaller sensor, the TZ100 offers a higher resolution of 20 megapixels, compared with 10 MP of the E-420. 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 2.41μm versus 4.74μm for the E-420). However, it should be noted that the TZ100 is much more recent (by 7 years and 10 months) than the E-420, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Panasonic TZ100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the TZ100 for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Olympus E-420 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.

The Olympus E-420 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Panasonic Lumix DMC-TZ100 are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.

E-420 versus TZ100 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 TZ100 offers substantially better image quality than the E-420 (overall score 14 points higher). The advantage is based on 1.3 bits higher color depth, 2.1 EV in additional dynamic range, and 0.1 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 TZ100 has an electronic viewfinder (1166k dots), while the E-420 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same magnification (0.46x), but the one in the TZ100 has a wider field of view (100%) than the finder in the E-420 (95%), so that a larger proportion of the captured image is visible. The following table reports on some other key feature differences and similarities of the Olympus E-420, the Panasonic TZ100, and comparable cameras.

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

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The TZ100 has a touchscreen, while the E-420 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 E-420 writes its imaging data to Compact Flash or xD Picture cards, while the TZ100 uses SDXC cards. The E-420 features dual card slots, which can be very useful in case a memory card fails. In contrast, the TZ100 only has one slot.

Connectivity comparison

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 Olympus E-420 and Panasonic Lumix DMC-TZ100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-420 has a hotshoe, while the TZ100 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the E-420 and the TZ100 have been discontinued, but can regularly be found used on eBay. The TZ100 was replaced by the Panasonic TZ200, while the E-420 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 Olympus and Panasonic websites.

Review summary

So how do things add up? Which of the two cameras – the Olympus E-420 or the Panasonic TZ100 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

ilogo

Arguments in favor of the Olympus E-420:

  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • Longer lasting: Can take more shots (500 versus 300) on a single battery charge.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been available for much longer (launched in March 2008).

ilogo

Reasons to prefer the Panasonic Lumix DMC-TZ100:

  • More detail: Has more megapixels (20 vs 10MP), which boosts linear resolution by 44%.
  • Better image quality: Scores substantially higher (14 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.3 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (2.1 EV of extra DR).
  • Broader imaging potential: Can capture not only stills but also 4K/30p video.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 215k dots).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (10 vs 3.5 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Ready to shoot: Comes with an integrated lens, while the E-420 requires a separate lens.
  • More compact: Is smaller (111x65mm vs 130x91mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the E-420).
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • More modern: Reflects 7 years and 10 months of technical progress since the E-420 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the TZ100 is the clear winner of the contest (21 : 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. 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.

E-420 07:21 TZ100

How about other alternatives? Do the specifications of the Olympus E-420 and the Panasonic TZ100 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Superzoom 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 incomplete and does no justice, for example, to the way the E-420 or the TZ100 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

Care should be taken when interpreting the review scores above, 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 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.
