Canon 1D Mark III versus Panasonic LX100

The Canon EOS-1D Mark III and the Panasonic Lumix DMC-LX100 are two digital cameras that were announced, respectively, in February 2007 and September 2014. The 1D Mark III is a DSLR, while the LX100 is a fixed lens compact. The cameras are based on an APS-H (1D Mark III) and a Four Thirds (LX100) sensor. The Canon has a resolution of 10.1 megapixel, whereas the Panasonic provides 12.7 MP. 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: Canon 1D Mark III vs Panasonic LX100

The side-by-side display below illustrates the physical size and weight of the Canon 1D Mark III and the Panasonic LX100. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter. You can also use the toggle button 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 – the 1D 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 LX100 is considerably smaller (69 percent) than the Canon 1D Mark III. It is worth mentioning in this context that the 1D Mark III is splash and dust resistant, while the LX100 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the LX100 has a lens build in, whereas the 1D 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 1D Mark III and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 1D Mark III gets 2200 shots out of its LP-E4 battery, while the LX100 can take 300 images on a single charge of its DMW-BLG10 power pack. As can be seen in the images above, the 1D Mark III has a battery grip build in. This facilitates image-taking in portrait orientation and gives it additional battery power.

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 LX100 was launched at a lower price than the 1D Mark III, despite having a lens build 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Canon 1D Mark III vs Panasonic LX100

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

Of the two cameras under consideration, the Canon 1D Mark III features an APS-H sensor and the Panasonic LX100 a Four Thirds sensor. The sensor area in the LX100 is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 2.0. The sensor in the 1D Mark III has a native 3:2 aspect ratio, while the one in the LX100 offers a 4:3 aspect.

In terms of underlying technology, both cameras are build around CMOS sensors.

Canon 1D Mark III and Panasonic LX100 sensor measures

Despite having a smaller sensor, the LX100 offers a higher resolution of 12.7 megapixel, compared with 10.1 MP of the 1D Mark III. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.21μm versus 7.21μm for the 1D Mark III). However, it should be noted that the LX100 is much more recent (by 7 years and 6 months) than the 1D Mark III, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

1D Mark III versus LX100 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 review, the 1D Mark III has a notably higher overall DXO score than the LX100 (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.4 bits higher color depth, 0.8 EV of lower dynamic range, and 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. The LX100 indeed provides for movie recording, while the 1D Mark III does not. The highest resolution format that the LX100 can use is 4K/30p.

 

Feature comparison: Canon 1D Mark III vs Panasonic LX100

Apart from body and sensor, cameras can and do differ across a range of features. For example, the LX100 has an electronic viewfinder (2764k dots), while the 1D 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 adjacent table lists some of the other core features of the Canon 1D Mark III and Panasonic LX100 along with similar information for a selection of comparators.

One feature that is present on the 1D Mark III, but is missing on the LX100 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, the LX100 features 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).

The 1D Mark III writes its imaging data to Compact Flash or SDHC cards, while the LX100 uses SDXC cards. The 1D Mark III features dual card slots, which can be very useful in case a memory card fails. In contrast, the LX100 only has one slot.

If the count of relative strengths (bullet points above) is taken as a measure, the LX100 emerges as the winner of the match-up (14 : 11 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.

1D Mark III 11:14 LX100

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 1D Mark III or the LX100. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. Thus, a score needs to be put into the context of the launch date and the launch price 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.
