Canon SX420 vs Nikon D7000
The Canon PowerShot SX420 IS and the Nikon D7000 are two digital cameras that were revealed to the public, respectively, in January 2016 and September 2010. The SX420 is a fixed lens compact, while the D7000 is a DSLR. The cameras are based on a 1/2.3-inch (SX420) and an APS-C (D7000) sensor. The Canon has a resolution of 19.9 megapixels, whereas the Nikon provides 16.1 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 Canon PowerShot SX420 IS and the Nikon D7000? 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 Canon SX420 and the Nikon D7000 are illustrated in the side-by-side display below. 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.
The SX420 can be obtained in two different colors (black, red), while the D7000 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 D7000 is considerably larger (93 percent) than the Canon SX420. It is noteworthy in this context that the D7000 is splash and dust-proof, while the SX420 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX420 has a lens built in, whereas the D7000 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 D7000 and their specifications in the Nikon Lens Catalog.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 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 SX420 was launched at a lower price than the D7000, despite having a lens built 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.
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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon SX420 features a 1/2.3-inch sensor and the Nikon D7000 an APS-C sensor. The sensor area in the D7000 is 1225 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.5. The sensor in the SX420 has a native 4:3 aspect ratio, while the one in the D7000 offers a 3:2 aspect.
Despite having a smaller sensor, the Canon SX420 offers a higher resolution of 19.9 megapixels, compared with 16.1 MP of the Nikon D7000. 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 1.19μm versus 4.80μm for the D7000). However, it should be noted that the SX420 is much more recent (by 5 years and 3 months) than the D7000, 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 SX420 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon SX420 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX420 for good quality output (200 dots per inch) amounts to 25.8 x 19.3 inches or 65.4 x 49.1 cm, for very good quality (250 dpi) 20.6 x 15.5 inches or 52.3 x 39.3 cm, and for excellent quality (300 dpi) 17.2 x 12.9 inches or 43.6 x 32.7 cm. The corresponding values for the Nikon D7000 are 24.6 x 16.3 inches or 62.6 x 41.5 cm for good quality, 19.7 x 13.1 inches or 50.1 x 33.2 cm for very good quality, and 16.4 x 10.9 inches or 41.7 x 27.6 cm for excellent quality prints.
The Canon PowerShot SX420 IS has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Nikon D7000 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-25600.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 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 two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the D7000 provides a better video resolution than the SX420. It can shoot movie footage at 10800/24p, while the Canon is limited to 720/25p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the D7000 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the SX420 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon SX420, the Nikon D7000, and comparable cameras.
|5.||Canon G7 X Mark II||none||n||3.0||1040||tilting||Y||1/2000s||8.0||Y||Y|
|8.||Canon G5 X||2360||n||3.0||1040||swivel||Y||1/2000s||5.9||Y||Y|
One feature that is present on the D7000, but is missing on the SX420 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 Nikon D7000 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.
Concerning the storage of imaging data, both the SX420 and the D7000 write their files to SDXC cards. The D7000 features dual card slots, which can be very useful in case a memory card fails. In contrast, the SX420 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 Canon PowerShot SX420 IS and Nikon D7000 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

|8.||Canon G5 X||Y||stereo||mono||-||-||mini||2.0||Y||Y||-|
It is notable that the SX420 offers wifi support, while the D7000 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the SX420 and the D7000 have been discontinued, but can regularly be found used on eBay. The D7000 was replaced by the Nikon D7100, while the SX420 was followed by the Canon SX430. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Nikon websites.
So what conclusions can be drawn? Which of the two cameras – the Canon SX420 or the Nikon D7000 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Canon PowerShot SX420 IS:
- More detail: Offers more megapixels (19.9 vs 16.1MP) with a 9% higher linear resolution.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Ready to shoot: Comes with a built-in lens, while the D7000 requires a separate lens.
- More compact: Is smaller (104x69mm vs 132x105mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the D7000).
- Sharper images: Has hand-shake reducing image stabilization built-in.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- 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 built-in lens.
- More modern: Reflects 5 years and 3 months of technical progress since the D7000 launch.
Arguments in favor of the Nikon D7000:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
- Richer colors: The pixel size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
- Better video: Provides higher definition movie capture (10800/24p vs 720/25p).
- Better sound: Can connect to an external microphone for higher quality sound recording.
- 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 detailed LCD: Has a higher resolution rear screen (921k vs 230k dots).
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (6 vs 0.5 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More flexible: Makes it possible to change lenses and thus to use specialty optics.
- Longer lasting: Gets more shots (1050 versus 195) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More heavily discounted: Has been around for much longer (launched in September 2010).
If the number of relative strengths (bullet points above) is taken as a guide, the D7000 is the clear winner of the contest (19 : 10 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 Canon SX420 and the Nikon D7000 place the cameras among the top in their class? Find out in the latest Best Superzoom 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 SX420 and the D7000 in practical situations. 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.
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], 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.

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 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.
