Canon T3i vs Nikon D3000

The Canon EOS Rebel T3i (called Canon 600D in some regions) and the Nikon D3000 are two digital cameras that were announced, respectively, in February 2011 and July 2009. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The Canon has a resolution of 17.9 megapixels, whereas the Nikon 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 Canon EOS Rebel T3i and the Nikon D3000? 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 side-by-side display below illustrates the physical size and weight of the Canon T3i and the Nikon D3000. 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.

Size Canon T3i vs Nikon D3000
Compare T3i versus D3000 top
Comparison T3i or D3000 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D3000 is notably smaller (8 percent) than the Canon T3i. Moreover, the D3000 is markedly lighter (6 percent) than the T3i. In this context, it is worth noting that neither the T3i nor the D3000 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. Yet, since both cameras are based around an APS-C sensor, their respective lenses will tend to have similar dimensions and heft. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (T3i) and the Nikon Lens Catalog (D3000).

Concerning battery life, the T3i gets 440 shots out of its LP-E8 battery, while the D3000 can take 500 images on a single charge of its EN-EL9a power pack.

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 naturally be influenced heavily by the price. 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 two cameras under review were launched at the same price and fall into the same 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the D3000 is 12 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (T3i) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon T3i and Nikon D3000 sensor measures

Despite having a smaller sensor, the Canon T3i offers a higher resolution of 17.9 megapixels, compared with 10 MP of the Nikon D3000. 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 4.31μm versus 6.11μm for the D3000). However, it should be noted that the T3i is a somewhat more recent model (by 1 year and 6 months) than the D3000, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.

The resolution advantage of the Canon T3i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T3i 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 D3000 are 19.4 x 13 inches or 49.2 x 32.9 cm for good quality, 15.5 x 10.4 inches or 39.3 x 26.3 cm for very good quality, and 12.9 x 8.6 inches or 32.8 x 21.9 cm for excellent quality prints.

The Canon EOS Rebel T3i 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 D3000 are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.

T3i versus D3000 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The T3i and the D3000 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinders of both cameras offer the same field of view (95%), as well as the same magnification (0.53x). The following table reports on some other key feature differences and similarities of the Canon T3i, the Nikon D3000, and comparable cameras.

Review summary

So how do things add up? Which of the two cameras – the Canon T3i or the Nikon D3000 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

ilogo

Arguments in favor of the Canon EOS Rebel T3i:

  • More detail: Offers more megapixels (17.9 vs 10MP) with a 34% higher linear resolution.
  • Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
  • Broader imaging potential: Can record not only still images but also 1080/30p movies.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (3.7 vs 3 flaps/sec) to capture the decisive moment.
  • More modern: Is somewhat more recent (announced 1 year and 6 months after the D3000).

ilogo

Reasons to prefer the Nikon D3000:

  • Longer lasting: Gets more shots (500 versus 440) out of a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in July 2009).

If the count of relative strengths (bullet points above) is taken as a measure, the T3i is the clear winner of the match-up (8 : 2 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

T3i 08:02 D3000

How about other alternatives? Do the specifications of the Canon T3i and the Nikon D3000 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the T3i or the D3000 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 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.

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

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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
