Panasonic TZ90 vs Sony A900

The Panasonic Lumix DC-TZ90 (called Panasonic ZS70 in some regions) and the Sony Alpha A900 are two digital cameras that were announced, respectively, in April 2017 and September 2008. The TZ90 is a fixed lens compact, while the A900 is a DSLR. The cameras are based on a 1/2.3-inch (TZ90) and a full frame (A900) sensor. The Panasonic has a resolution of 20.2 megapixels, whereas the Sony provides 24.4 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 DC-TZ90 and the Sony Alpha A900? 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: Panasonic TZ90 vs Sony A900

The physical size and weight of the Panasonic TZ90 and the Sony A900 are illustrated 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 TZ90 can be obtained in two different colors (black, silver), while the A900 is only available in black.

Compare TZ90 versus A900 top
Comparison TZ90 or A900 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A900 is considerably larger (143 percent) than the Panasonic TZ90. It is noteworthy in this context that the A900 is splash and dust-proof, while the TZ90 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the TZ90 has a lens built in, whereas the A900 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

Concerning battery life, the TZ90 gets 380 shots out of its DMW-BLG10 battery, while the A900 can take 880 images on a single charge of its NP-FM500H power pack. The power pack in the TZ90 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

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

Any camera decision will obviously take relative prices into account. 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. The TZ90 was launched at a lower price than the A900, despite having a lens built in. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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: Panasonic TZ90 vs Sony A900

The size of the sensor inside a digital camera is one of the key determinants 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic TZ90 features a 1/2.3-inch sensor and the Sony A900 a full frame sensor. The sensor area in the A900 is 2979 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.0. The sensor in the TZ90 has a native 4:3 aspect ratio, while the one in the A900 offers a 3:2 aspect.

Panasonic TZ90 and Sony A900 sensor measures

With 24.4MP, the A900 offers a higher resolution than the TZ90 (20.2MP), but the A900 nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 1.18μm for the TZ90) due to its larger sensor. However, the TZ90 is a much more recent model (by 8 years and 7 months) than the A900, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the TZ90 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony A900 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A900 for good quality output (200 dots per inch) amounts to 30.2 x 20.2 inch or 76.8 x 51.2 cm, for very good quality (250 dpi) 24.2 x 16.1 inch or 61.4 x 41 cm, and for excellent quality (300 dpi) 20.2 x 13.4 inch or 51.2 x 34.1 cm. The corresponding values for the Panasonic TZ90 are 25.9 x 19.4 inch or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inch or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inch or 43.9 x 32.9 cm for excellent quality prints.

The Panasonic Lumix DC-TZ90 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 A900 are ISO 200 to ISO 3200, with the possibility to increase the ISO range to 100-6400.

TZ90 versus A900 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 A900 offers substantially better image quality than the TZ90 (overall score 43 points higher). The advantage is based on 4.6 bits higher color depth, 1.7 EV in additional dynamic range, and 3.8 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. The TZ90 indeed provides movie recording capabilities, while the A900 does not. The highest resolution format that the TZ90 can use is 4K/30p.

 

Feature comparison: Panasonic TZ90 vs Sony A900

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the TZ90 has an electronic viewfinder (1166k dots), while the A900 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 field of view (100%), but the viewfinder of the A900 has a higher magnification than the one of the TZ90 (0.74x vs 0.46x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Panasonic TZ90 and Sony A900 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The TZ90 has one, while the A900 does not. While the built-in flash of the TZ90 is not very powerful, it can at times be useful as a fill-in light.

The TZ90 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the A900 does not have a selfie-screen.

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 TZ90 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 TZ90 writes its imaging data to SDXC cards, while the A900 uses Compact Flash or Memory Stick PRO Duo cards. The A900 features dual card slots, which can be very useful in case a memory card fails. In contrast, the TZ90 only has one slot.

 

Connectivity comparison: Panasonic TZ90 vs Sony A900

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 DC-TZ90 and Sony Alpha A900 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the TZ90 offers wifi support, while the A900 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Sony A900 (unlike the TZ90) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the TZ90 and the A900 have been discontinued, but can regularly be found used on eBay. The A900 was replaced by the Sony A99, while the TZ90 was followed by the Panasonic TZ95. 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.


Review summary: Panasonic TZ90 vs Sony A900

So what conclusions can be drawn? Is there a clear favorite between the Panasonic TZ90 and the Sony A900? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Sony Alpha A900:

  • More detail: Has more megapixels (24.4 vs 20.2MP), which boosts linear resolution by 12%.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Scores substantially higher (43 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (4.6 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.7 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (3.8 stops ISO advantage).
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.74x vs 0.46x).
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
  • More flexible: Makes it possible to change lenses and thus to use specialty optics.
  • Longer lasting: Gets more shots (880 versus 380) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been around for much longer (launched in September 2008).

If the number of relative strengths (bullet points above) is taken as a guide, the A900 comes out slightly ahead of the TZ90 (17 : 16 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.

How about other alternatives? Do the specifications of the Panasonic TZ90 and the Sony A900 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best DSLR 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 says little about, for example, the shooting experience and imaging performance of the TZ90 and the A900 in practical situations. 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: Panasonic TZ90 vs Sony A900

This is where reviews by experts come in. 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.

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

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
