Going beyond this snapshot of core features and characteristics, what are the differences between the Leica X Vario (Typ 107) and the Nikon D100? 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.

Body comparison

The physical size and weight of the Leica X Vario and the Nikon D100 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 dimensions are rounded to the nearest millimeter.

The X Vario can be obtained in two different colors (black, silver), while the D100 is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D100 is considerably larger (72 percent) than the Leica X Vario. In this context, it is worth noting that neither the X Vario nor the D100 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X Vario has a lens built in, whereas the D100 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 D100 and their specifications in the Nikon Lens Catalog.

Concerning battery life, the X Vario gets 450 shots out of its Leica BP-DC8 battery, while the D100 can take 370 images on a single charge of its Nikon EN-EL3 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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.

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. 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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 16.1MP, the X Vario offers a higher resolution than the D100 (6MP), but the X Vario has smaller individual pixels (pixel pitch of 4.80μm versus 7.85μm for the D100). However, the X Vario is a much more recent model (by 11 years and 3 months) than the D100, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

The resolution advantage of the Leica X Vario implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X Vario for good quality output (200 dots per inch) amounts to 24.6 x 16.4 inches or 62.6 x 41.6 cm, for very good quality (250 dpi) 19.7 x 13.1 inches or 50.1 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.7 x 27.7 cm. The corresponding values for the Nikon D100 are 15 x 10 inches or 38.2 x 25.4 cm for good quality, 12 x 8 inches or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inches or 25.5 x 16.9 cm for excellent quality prints.

The Leica X Vario (Typ 107) has a native sensitivity range from ISO 100 to ISO 12500. The corresponding ISO settings for the Nikon D100 are ISO 200 to ISO 800, with the possibility to increase the ISO range to 200-1600.

In terms of underlying technology, the X Vario is build around a CMOS sensor, while the D100 uses a CCD imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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 cannot only take still pictures, but also record videos. The X Vario indeed provides movie recording capabilities, while the D100 does not. The highest resolution format that the X Vario can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the D100 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the X Vario relies on live view and the rear LCD for framing. That said, the X Vario can be equipped with an optional viewfinder – the EVF 2. The following table reports on some other key feature differences and similarities of the Leica X Vario, the Nikon D100, and comparable cameras.

One feature that is present on the D100, but is missing on the X Vario 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 X Vario writes its imaging data to SDXC cards, while the D100 uses Compact Flash cards.

Connectivity comparison

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 Leica X Vario (Typ 107) and Nikon D100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the X Vario and the D100 have been discontinued, but can regularly be found used on ebay. The D100 was replaced by the Nikon D200, while the X Vario does not have a direct successor. Further information on the features and operation of the X Vario and D100 can be found, respectively, in the Leica X Vario Manual (free pdf) or the online Nikon D100 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Leica X Vario and the Nikon D100? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Leica X Vario (Typ 107):

• More detail: Offers more megapixels (16.1 vs 6MP) with a 64% higher linear resolution.
• Broader imaging potential: Can record not only still images but also 1080/30p movies.
• Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (920k vs 118k dots).
• Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
• Ready to shoot: Comes with a built-in lens, while the D100 requires a separate lens.
• More compact: Is smaller (133x73mm vs 144x116mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the D100).
• Longer lasting: Can take more shots (450 versus 370) on a single battery charge.
• Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More modern: Reflects 11 years and 3 months of technical progress since the D100 launch.

Arguments in favor of the Nikon D100:

• Easier framing: Has an optical viewfinder for image composition and settings control.
• Easier setting verification: Features a control panel on top to check shooting parameters.
• 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.
• More heavily discounted: Has been around for much longer (launched in February 2002).

If the count of individual advantages (bullet points above) is taken as a guide, the X Vario is the clear winner of the match-up (12 : 5 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 Leica X Vario and the Nikon D100 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the X Vario and the D100 in practical situations. 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.

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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

Care should be taken when interpreting the review scores above, 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 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.
