Canon 5D Mark III versus Panasonic FZ1000

The Canon EOS 5D Mark III and the Panasonic Lumix DMC-FZ1000 are two digital cameras that were revealed to the public, respectively, in March 2012 and June 2014. The 5D Mark III is a DSLR, while the FZ1000 is a fixed lens compact. The cameras are based on a full frame (5D Mark III) and an one-inch sensor. The Canon has a resolution of 22.1 megapixel, whereas the Panasonic provides 20 MP.

Body comparison

An illustration of the physical size and weight of the Canon 5D Mark III and the Panasonic FZ1000 is provided in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. 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 5D Mark III – represents 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic FZ1000 is notably smaller (23 percent) than the Canon 5D Mark III. It is worth mentioning in this context that the 5D Mark III is splash and dust resistant, while the FZ1000 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the FZ1000 has a lens build in, whereas the 5D Mark III is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the 5D Mark III and their specifications in the Canon EF Lens Catalog.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The FZ1000 was launched at a lower price than the 5D Mark III, despite having a lens build in. 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 sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixel-units 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 tent to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 5D Mark III features a full frame sensor and the Panasonic FZ1000 an one-inch sensor. The sensor area in the FZ1000 is 87 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sensor size

With 22.1MP, the 5D Mark III offers a higher resolution than the FZ1000 (20MP), but the 5D Mark III nevertheless has larger individual pixels (pixel pitch of 6.25μm versus 2.41μm for the FZ1000) due to its larger sensor. However, the FZ1000 is a somewhat more recent model (by 2 years and 3 months) than the 5D Mark III, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

Sensor resolution

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the 5D Mark III provides substantially higher image quality than the FZ1000, with an overall score that is 17 points higher. This advantage is based on 1.9 bits higher color depth, and 2.1 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.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the FZ1000 provides a better video resolution than the 5D Mark III. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the FZ1000 has an electronic viewfinder (2359k dots), while the 5D Mark III 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 following table reports on some other key feature differences and similarities of the Canon 5D Mark III, the Panasonic FZ1000, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Reasons to prefer the Panasonic Lumix DMC-FZ1000:

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster burst: Shoots at higher frequency (12 vs 6 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with an integrated lens, while the 5D Mark III requires a separate lens.
  • More compact: Is smaller (137x99mm vs 152x116mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens build in (unlike the 5D Mark III).
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced at a lower price, despite coming with a build-in lens.
  • More modern: Reflects 2 years and 3 months of technical progress since the 5D Mark III launch.

If the count of individual advantages (bullet points above) is taken as a guide, the 5D Mark III emerges as the winner of the contest (13 : 10 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.

5D Mark III 13:10 FZ1000

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 5D Mark III or the FZ1000. 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 where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, 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, please note that some of the review sites have changed their methodology and reporting over time.
