Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-FZ100 and the Sony Alpha SLT-A58? 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.
The physical size and weight of the Panasonic FZ100 and the Sony A58 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 width, height and depth measures are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A58 is notably larger (21 percent) than the Panasonic FZ100. In this context, it is worth noting that neither the FZ100 nor the A58 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the FZ100 has a lens built in, whereas the A58 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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 FZ100 was launched at a lower price than the A58, 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.
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. 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 FZ100 features a 1/2.3-inch sensor and the Sony A58 an APS-C sensor. The sensor area in the A58 is 1211 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.5. The sensor in the FZ100 has a native 4:3 aspect ratio, while the one in the A58 offers a 3:2 aspect.
With 19.8MP, the A58 offers a higher resolution than the FZ100 (14MP), but the A58 nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 1.41μm for the FZ100) due to its larger sensor. Moreover, the A58 is a much more recent model (by 2 years and 7 months) than the FZ100, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the FZ100 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Sony A58 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A58 for good quality output (200 dots per inch) amounts to 27.3 x 18.2 inches or 69.3 x 46.1 cm, for very good quality (250 dpi) 21.8 x 14.5 inches or 55.4 x 36.9 cm, and for excellent quality (300 dpi) 18.2 x 12.1 inches or 46.2 x 30.8 cm. The corresponding values for the Panasonic FZ100 are 21.6 x 16.2 inches or 54.9 x 41.1 cm for good quality, 17.3 x 13 inches or 43.9 x 32.9 cm for very good quality, and 14.4 x 10.8 inches or 36.6 x 27.4 cm for excellent quality prints.
The Panasonic Lumix DMC-FZ100 has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-6400. The corresponding ISO settings for the Sony Alpha SLT-A58 are ISO 100 to ISO 16000, with the possibility to increase the ISO range to 100-25600.
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"). 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. 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 (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 A58 offers a substantially higher resolution than the one in the FZ100 (1440k vs 202k dots). The table below summarizes some of the other core capabilities of the Panasonic FZ100 and Sony A58 in connection with corresponding information for a sample of similar cameras.

|Leica V-LUX 2||202||n||3.0||460||swivel||n||1/2000s||11.0||Y||Y|
The FZ100 writes its imaging data to SDXC cards, while the A58 uses SDXC or Memory Stick PRO Duo 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-FZ100 and Sony Alpha SLT-A58 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

|Leica V-LUX 2||Y||stereo||mono||-||-||mini||2.0||-||-||-|
It is notable that the A58 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The FZ100 does not feature such a mic input.
Both the FZ100 and the A58 have been discontinued, but can regularly be found used on eBay. The FZ100 was replaced by the Panasonic FZ150, while the A58 was followed by the Sony A68. 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 how do things add up? Is there a clear favorite between the Panasonic FZ100 and the Sony A58? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

- Better sound: Can connect to an external microphone for higher quality sound recording.
- More detailed viewfinder: Has higher resolution electronic viewfinder (1440k vs 202k dots).
- Faster shutter: Has higher mechanical shutter speed (1/4000s 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 (690 versus 410) out of a single battery charge.
- More modern: Reflects 2 years and 7 months of technical progress since the FZ100 launch.
If the count of relative strengths (bullet points above) is taken as a measure, the A58 emerges as the winner of the match-up (12 : 9 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 FZ100 and the Sony A58 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 technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the FZ100 and the A58 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 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.

The review scores listed above should be treated 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. 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, please note that some of the review sites have changed their methodology and reporting over time.
