Nikon D750 versus Canon G9 X

The Nikon D750 and the Canon PowerShot G9 X are two digital cameras that were officially introduced, respectively, in September 2014 and October 2015. The D750 is a DSLR, while the G9X is a fixed lens compact. The cameras are based on a full frame (D750) and an one-inch (G9X) sensor. The Nikon has a resolution of 24.2 megapixel, whereas the Canon provides 20 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Nikon D750 vs Canon G9 X

The side-by-side display below illustrates the physical size and weight of the Nikon D750 and the Canon G9 X. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the D750 – represents the basis or 100 percent 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 Canon G9 X is considerably smaller (64 percent) than the Nikon D750. It is worth mentioning in this context that the D750 is splash and dust resistant, while the G9X does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G9X has a lens build in, whereas the D750 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the D750 and their specifications in the Nikon Lens Catalog.

Concerning battery life, the D750 gets 1230 shots out of its EN-EL15 battery, while the G9X can take 220 images on a single charge of its NB-13L 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, 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.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G9X was launched at a lower price than the D750, despite having a lens build in. 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 D750 vs Canon G9 X

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.

Of the two cameras under consideration, the Nikon D750 features a full frame sensor and the Canon G9 X an one-inch sensor. The sensor area in the G9X is 87 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Nikon D750 and Canon G9 X sensor measures

With 24.2MP, the D750 offers a higher resolution than the G9X (20MP), but the D750 nevertheless has larger individual pixels (pixel pitch of 5.97μm versus 2.41μm for the G9X) due to its larger sensor. However, the G9X is a somewhat more recent model (by 1 year and 1 month) than the D750, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

D750 versus G9X MP

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"). Of the two cameras under review, the D750 provides substantially higher image quality than the G9X, with an overall score that is 30 points higher. This advantage is based on 3.3 bits higher color depth, 2.2 EV in additional dynamic range, and 2.6 stops in additional low light sensitivity. 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 also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/60p).

 

Feature comparison: Nikon D750 vs Canon G9 X

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the D750 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G9X relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Nikon D750 and Canon G9 X in connection with corresponding information for a sample of similar cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

One feature that is present on the D750, but is missing on the G9X 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.

Both the D750 and the G9X write their imaging data to SDXC cards. The D750 features dual card slots, which can be very useful in case a memory card fails. In contrast, the G9X only has one slot.

Advantages of the Canon PowerShot G9 X:

  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Ready to shoot: Comes with an integrated lens, while the D750 requires a separate lens.
  • More compact: Is smaller (98x58mm vs 141x113mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens build in (unlike the D750).
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced at a lower price, despite coming with a build-in lens.
  • More modern: Was introduced somewhat (1 year and 1 month) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the D750 is the clear winner of the match-up (19 : 8 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.

D750 19:08 G9X

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the D750 and the G9X 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 why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
