Fujifilm X-A7 vs Olympus E-400
The Fujifilm X-A7 and the Olympus E-400 are two digital cameras that were revealed to the public, respectively, in September 2019 and September 2006. The X-A7 is a mirrorless interchangeable lens camera, while the E-400 is a DSLR. The cameras are based on an APS-C (X-A7) and a Four Thirds (E-400) sensor. The Fujifilm has a resolution of 24 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.

Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X-A7 and the Olympus E-400? 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.
The physical size and weight of the Fujifilm X-A7 and the Olympus E-400 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 measures are rounded to the nearest millimeter.
The X-A7 can be obtained in four different colors (silver, graphite, brown, green), while the E-400 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 Olympus E-400 is considerably larger (46 percent) than the Fujifilm X-A7. Moreover, the E-400 is substantially heavier (36 percent) than the X-A7. In this context, it is worth noting that neither the X-A7 nor the E-400 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Fujinon X Lens Catalog (X-A7) and the Four Thirds Lens Catalog (E-400). Mirrorless cameras, such as the Fujifilm X-A7, 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-A7 gets 440 shots out of its NP-W126S battery, while the E-400 can take 500 images on a single charge of its BLS-1 power pack. The power pack in the X-A7 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

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. The X-A7 was launched at a markedly lower price (by 29 percent) than the E-400, which puts it into a different market segment. 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.
The size of the sensor inside a digital camera is one of the key determinants 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. 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Fujifilm X-A7 features an APS-C sensor and the Olympus E-400 a Four Thirds sensor. The sensor area in the E-400 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 X-A7 has a native 3:2 aspect ratio, while the one in the E-400 offers a 4:3 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 24MP, the X-A7 offers a higher resolution than the E-400 (10MP), but the X-A7 has smaller individual pixels (pixel pitch of 3.92μm versus 4.74μm for the E-400). However, the X-A7 is a much more recent model (by 13 years) than the E-400, 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 Fujifilm X-A7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-A7 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Olympus E-400 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 Fujifilm X-A7 has a native sensitivity range from ISO 200 to ISO 12800, which can be extended to ISO 200-51200. The corresponding ISO settings for the Olympus E-400 are ISO 100 to ISO 1600 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The X-A7 indeed provides movie recording capabilities, while the E-400 does not. The highest resolution format that the X-A7 can use is 4K/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the E-400 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the X-A7 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-A7, the Olympus E-400, and comparable cameras.
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The X-A7 has a touchscreen, while the E-400 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The X-A7 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the E-400 does not have a selfie-screen.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the X-A7 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Fujifilm X-A7 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The X-A7 writes its imaging data to SDXC cards, while the E-400 uses Compact Flash or xD Picture cards. The E-400 features dual card slots, which can be very useful in case a memory card fails. In contrast, the X-A7 only has one slot.
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-A7 and Olympus E-400 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.
| WiFi |
It is notable that the X-A7 offers wifi support, while the E-400 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
The X-A7 is a recent model that features in the current product line-up of Fujifilm. In contrast, the E-400 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-400 was succeeded by the Olympus E-410. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm and Olympus websites.
So what conclusions can be drawn? Is there a clear favorite between the Fujifilm X-A7 and the Olympus E-400? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

- More heavily discounted: Has been around for much longer (launched in September 2006).
If the number of relative strengths (bullet points above) is taken as a guide, the X-A7 is the clear winner of the match-up (21 : 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the X-A7 and the E-400 in practical situations. 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 where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

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. A score, therefore, has to be seen in close connection to the price and market introduction time 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
