Leica X1 vs Olympus E-420

The Leica X1 and the Olympus E-420 are two digital cameras that were announced, respectively, in September 2009 and March 2008. The X1 is a fixed lens compact, while the E-420 is a DSLR. The cameras are based on an APS-C (X1) and a Four Thirds (E-420) sensor. The Leica has a resolution of 12.2 megapixels, whereas the Olympus provides 10 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

An illustration of the physical size and weight of the Leica X1 and the Olympus E-420 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.

The X1 can be obtained in two different colors (black, silver), while the E-420 is only available in black.

Size Leica X1 vs Olympus E-420
Compare X1 versus E-420 top
Comparison X1 or E-420 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-420 is considerably larger (59 percent) than the Leica X1. In this context, it is worth noting that neither the X1 nor the E-420 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X1 has a lens built in, whereas the E-420 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the E-420 and their specifications in the Four Thirds Lens Catalog.

Concerning battery life, the X1 gets 260 shots out of its Leica BP-DC8 battery, while the E-420 can take 500 images on a single charge of its Olympus BLS-1 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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

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. 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.

Of the two cameras under consideration, the Leica X1 features an APS-C sensor and the Olympus E-420 a Four Thirds sensor. The sensor area in the E-420 is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the X1 has a native 3:2 aspect ratio, while the one in the E-420 offers a 4:3 aspect.

Leica X1 and Olympus E-420 sensor measures

With 12.2MP, the X1 offers a higher resolution than the E-420 (10MP), but the X1 nevertheless has larger individual pixels (pixel pitch of 5.51μm versus 4.74μm for the E-420) due to its larger sensor. Moreover, the X1 is a somewhat more recent model (by 1 year and 6 months) than the E-420, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Leica X1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X1 for good quality output (200 dots per inch) amounts to 21.4 x 14.3 inches or 54.3 x 36.3 cm, for very good quality (250 dpi) 17.1 x 11.4 inches or 43.4 x 29 cm, and for excellent quality (300 dpi) 14.2 x 9.5 inches or 36.2 x 24.2 cm. The corresponding values for the Olympus E-420 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.

The Leica X1 has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Olympus E-420 are ISO 100 to ISO 1600 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

X1 versus E-420 MP

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"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-420 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the X1 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Leica X1 and Olympus E-420 in connection with corresponding information for a sample of similar cameras.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Leica X1 or the Olympus E-420 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the Leica X1:

  • More detail: Offers more megapixels (12.2 vs 10MP) with a 13% higher linear resolution.
  • Better image quality: Features a larger and more technologically advanced imaging sensor.
  • Richer colors: The sensor size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
  • Ready to shoot: Comes with a built-in lens, while the E-420 requires a separate lens.
  • More compact: Is smaller (124x60mm vs 130x91mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the E-420).
  • More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
  • More modern: Is somewhat more recent (announced 1 year and 6 months after the E-420).

ilogo

Advantages of the Olympus E-420:

  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
  • Faster burst: Shoots at higher frequency (3.5 vs 3 flaps/sec) to capture the decisive moment.
  • More flexible: Makes it possible to change lenses and thus to use specialty optics.
  • Longer lasting: Gets more shots (500 versus 260) out of a single battery charge.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been on the market for longer (launched in March 2008).

If the count of relative strengths (bullet points above) is taken as a measure, the X1 emerges as the winner of the contest (10 : 7 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 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.

X1 10:07 E-420

How about other alternatives? Do the specifications of the Leica X1 and the Olympus E-420 place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the X1 or the E-420. 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

This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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 above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
