Body comparison: Nikon D90 vs Fujifilm X-A3

The side-by-side display below illustrates the physical size and weight of the Nikon D90 and the Fujifilm X-A3. 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. 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 side – the D90 – represents the basis for the calculations 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 Fujifilm X-A3 is considerably smaller (42 percent) than the Nikon D90. Moreover, the X-A3 is substantially lighter (52 percent) than the D90. In this context, it is worth noting that neither the D90 nor the X-A3 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 Nikon Lens Catalog (D90) and the Fujinon X Lens Catalog (X-A3). Mirrorless cameras, such as the X-A3, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the D90 gets 850 shots out of its EN-EL3e battery, while the X-A3 can take 410 images on a single charge of its NP-W126S power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will obviously take relative prices into account. 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-A3 was launched at a markedly lower price (by 69 percent) than the D90, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Nikon D90 vs Fujifilm X-A3

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 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 X-A3 is 1 percent smaller. 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.

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

Nikon D90 and Fujifilm X-A3 sensor measures

Despite having a slightly smaller sensor, the X-A3 offers a higher resolution of 24 megapixel, compared with 12.2 MP of the D90. 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 3.92μm versus 5.53μm for the D90). However, it should be noted that the X-A3 is much more recent (by 8 years) than the D90, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The Nikon D90 has a native sensitivity range from ISO 200 to ISO 3200, which can be extended to ISO 200-6400. The corresponding ISO settings for the Fujifilm X-A3 are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-25600..

D90 versus X-A3 MP

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.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the X-A3 provides a better video resolution than the D90. It can shoot movie footage at 1080/60p, while the Nikon is limited to 720/24p.

 

Feature comparison: Nikon D90 vs Fujifilm X-A3

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the D90 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the X-A3 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Nikon D90 and Fujifilm X-A3 along with similar information for a selection of comparators. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

One feature that is present on the D90, but is missing on the X-A3 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-A3 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the D90 does not have a selfie-screen.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the X-A3 features an 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 D90 writes its imaging data to SDHC cards, while the X-A3 uses SDXC cards.

Connectivity comparison: Nikon D90 vs Fujifilm X-A3

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.

It is notable that the X-A3 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D90 does not offer wifi capability.

Both the D90 and the X-A3 have been discontinued, but can regularly be found used on eBay. The D90 was replaced by the Nikon D7000, while the X-A3 was followed by the Fujifilm X-A5.

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.

D90 04:14 X-A3

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the D90 or the X-A3. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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.
