Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X-M1 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

An illustration of the physical size and weight of the Fujifilm X-M1 and the Nikon D100 is provided 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-M1 can be obtained in three different colors (black, silver, brown), 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 (113 percent) than the Fujifilm X-M1. Moreover, the D100 is substantially heavier (136 percent) than the X-M1. In this context, it is worth noting that neither the X-M1 nor the D100 are weather-sealed.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Fujinon X Lens Catalog (X-M1) and the Nikon Lens Catalog (D100). Mirrorless cameras, such as the Fujifilm X-M1, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.

Concerning battery life, the X-M1 gets 350 shots out of its Fujifilm NP-W126 battery, while the D100 can take 370 images on a single charge of its Nikon EN-EL3 power pack.

Any camera decision will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The X-M1 was launched at a markedly lower price (by 65 percent) than the D100, which puts it into a different market segment. 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 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. 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. The sensor area in the D100 is 1 percent bigger. 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.

Despite having a slightly smaller sensor, the Fujifilm X-M1 offers a higher resolution of 16 megapixels, compared with 6 MP of the Nikon D100. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.80μm versus 7.85μm for the D100). However, it should be noted that the X-M1 is much more recent (by 11 years and 4 months) than the D100, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the X-M1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Fujifilm X-M1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-M1 for good quality output (200 dots per inch) amounts to 24.5 x 16.3 inches or 62.2 x 41.5 cm, for very good quality (250 dpi) 19.6 x 13.1 inches or 49.7 x 33.2 cm, and for excellent quality (300 dpi) 16.3 x 10.9 inches or 41.5 x 27.6 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 Fujifilm X-M1 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-25600. 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-M1 is build around a CMOS sensor, while the D100 uses a CCD imager. The X-M1 uses Fujifilm's X-Trans layout of photosites, while the D100 employs the more common Bayer array.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. The X-M1 indeed provides movie recording capabilities, while the D100 does not. The highest resolution format that the X-M1 can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the D100 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the X-M1 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Fujifilm X-M1, the Nikon D100, and comparable cameras.

One feature that is present on the D100, but is missing on the X-M1 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-M1 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 Fujifilm X-M1 and Nikon D100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X-M1 offers wifi support, while the D100 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the X-M1 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-M1 does not have a direct successor. Further information on the features and operation of the X-M1 and D100 can be found, respectively, in the Fujifilm X-M1 Manual (free pdf) or the online Nikon D100 Manual.

Review summary

So what is the bottom line? Is the Fujifilm X-M1 better than the Nikon D100 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Fujifilm X-M1:

• More detail: Offers more megapixels (16 vs 6MP) with a 63% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• 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).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Faster burst: Shoots at higher frequency (5.6 vs 3 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (117x67mm vs 144x116mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 450g or 58 percent) and hence easier to carry around.
• More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
• Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• More affordable: Was introduced into a lower priced category (65 percent cheaper at launch).
• More modern: Reflects 11 years and 4 months of technical progress since the D100 launch.

Arguments in favor of the Nikon D100:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• 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.
• More heavily discounted: Has been around for much longer (launched in February 2002).

If the number of relative strengths (bullet points above) is taken as a guide, the X-M1 is the clear winner of the match-up (14 : 4 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 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 Fujifilm X-M1 and the Nikon D100 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens 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 X-M1 or the D100. 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 why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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.
