Sony RX10 IV versus Panasonic FZ2500

The Sony Cyber-shot DSC-RX10 IV and the Panasonic Lumix DMC-FZ2500 (labelled Panasonic FZ2000 in some countries) are two digital cameras that were revealed to the public, respectively, in September 2017 and September 2016. Both the RX10 IV and the FZ2500 are fixed lens compact cameras that are equipped with an one-inch sensor. Both cameras offer a resolution of 20 megapixel. 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: Sony RX10 IV vs Panasonic FZ2500

The side-by-side display below illustrates the physical size and weight of the Sony RX10 IV and the Panasonic FZ2500. 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. You can also toggle the display 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 RX10 IV – represents the basis for the calculations across all the size and weight measures).

Any camera purchase 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 FZ2500 was launched at a markedly lower price (by 29 percent) than the RX10 IV, which puts it into a different market segment. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Sony RX10 IV vs Panasonic FZ2500

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 2.7. 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.

Sony RX10 IV and Panasonic FZ2500 sensor measures

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 RX10 IV and the FZ2500 have the same pixel density, as well as the same pixel size. It should, however, be noted that the RX10 IV is a somewhat more recent model (by 11 months) than the FZ2500, and its sensor might have benefitted from technological advances during this time.

The RX10 IV has on-sensor phase detect pixels, which results in relatively fast and reliable autofocus acquisition during video recording.

Many modern cameras are not only capable of taking still images, but can also record movies. 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: Sony RX10 IV vs Panasonic FZ2500

Apart from 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 FZ2500 offers a slightly higher resolution than the one in the RX10 IV (2360k vs 2359k dots).

One feature that is present on the RX10 IV, but is missing on the FZ2500 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

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 RX10 IV and the FZ2500 have zoom lenses build in. The RX10 IV has a 24-600mm f/2.4-4.0 optic and the FZ2500 offers a 24-480mm f/2.8-4.5 (focal lengths in full frame equivalent terms). Hence, the Sony and Panasonic provide the same view at the wide-angle end, but the Panasonic has less tele-photo reach at the long end. The RX10 IV offers the faster maximum aperture.

The RX10 IV writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the FZ2500 uses SDXC cards.

Both the RX10 IV and the FZ2500 are recent models that feature in their makers' current product line-up. The FZ2500 replaced the earlier Panasonic FZ1000, while the RX10 IV followed on from the Sony RX10 III.

Review summary: Sony RX10 IV vs Panasonic FZ2500

So what is the bottom line? Is the Sony RX10 IV better than the Panasonic FZ2500 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

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

  • Better video autofocus: Features on-sensor phase-detection for more confident movie autofocus.
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (1440k vs 1040k dots).
  • Faster burst: Shoots at higher frequency (24 vs 12 flaps/sec) to capture the decisive moment.
  • Better light gathering: Has a lens with a wider maximum aperture (f/2.4 vs f/2.8).
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • More compact: Is smaller (133x94mm vs 138x102mm) and thus needs less room in the bag.
  • Longer lasting: Can take more shots (400 versus 350) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More modern: Is somewhat more recent (announced 11 months after the FZ2500).

ilogo

Arguments in favor of the Panasonic Lumix DMC-FZ2500:

  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • Less heavy: Has a lower weight (by 180g or 16 percent) and is thus easier to take along.
  • More affordable: Was introduced into a lower priced category (29 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in September 2016).

If the count of individual advantages (bullet points above) is taken as a guide, the RX10 IV is the clear winner of the match-up (11 : 5 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.

RX10 IV 11:05 FZ2500

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the RX10 IV or the FZ2500. 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 why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
