Canon T2i vs Nikon L840

The Canon EOS Rebel T2i (called Canon 550D in some regions) and the Nikon Coolpix L840 are two digital cameras that were announced, respectively, in February 2010 and February 2015. The T2i is a DSLR, while the L840 is a fixed lens compact. The cameras are based on an APS-C (T2i) and a 1/2.3-inch (L840) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Nikon provides 15.9 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 EOS Rebel T2i and the Nikon Coolpix L840? 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

The physical size and weight of the Canon T2i and the Nikon L840 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 L840 can be obtained in two different colors (black, red), while the T2i is only available in black.

Size Canon T2i vs Nikon L840
Compare T2i versus L840 top
Comparison T2i or L840 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon L840 is considerably smaller (30 percent) than the Canon T2i. In this context, it is worth noting that neither the T2i nor the L840 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the L840 has a lens built in, whereas the T2i 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 T2i and their specifications in the Canon EF Lens Catalog.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 L840 was launched at a lower price than the T2i, despite having a lens built in. 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon T2i features an APS-C sensor and the Nikon L840 a 1/2.3-inch sensor. The sensor area in the L840 is 92 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 5.6. The sensor in the T2i has a native 3:2 aspect ratio, while the one in the L840 offers a 4:3 aspect.

Canon T2i and Nikon L840 sensor measures

With 17.9MP, the T2i offers a higher resolution than the L840 (15.9MP), but the T2i nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 1.33μm for the L840) due to its larger sensor. However, the L840 is a much more recent model (by 5 years) than the T2i, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the L840 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon T2i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T2i for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Nikon L840 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.

The Canon EOS Rebel T2i has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Nikon Coolpix L840 are ISO 100 to ISO 6400 (no boost).

T2i versus L840 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon T2i and the Nikon L840? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Advantages of the Canon EOS Rebel T2i:

  • More detail: Offers more megapixels (17.9 vs 15.9MP) with a 8% higher linear resolution.
  • 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 sound: Can connect to an external microphone for higher quality sound recording.
  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • More heavily discounted: Has been available for much longer (launched in February 2010).

ilogo

Reasons to prefer the Nikon Coolpix L840:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster burst: Shoots at higher frequency (7.4 vs 3.7 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with an integrated lens, while the T2i requires a separate lens.
  • More compact: Is smaller (113x78mm vs 129x98mm) and will fit more readily into a bag.
  • Longer lasting: Gets more shots (590 versus 440) out of a single battery charge.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • 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 of technical progress since the T2i launch.

If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (12 points each). 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.

T2i 12:12 L840

How about other alternatives? Do the specifications of the Canon T2i and the Nikon L840 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Superzoom 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 remains incomplete and does no justice, for example, to the way the T2i or the L840 perform in practice. 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 hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
