Canon T4i vs Panasonic G3

The Canon EOS Rebel T4i (called Canon 650D in some regions) and the Panasonic Lumix DMC-G3 are two digital cameras that were announced, respectively, in June 2012 and May 2011. The T4i is a DSLR, while the G3 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (T4i) and a Four Thirds (G3) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Panasonic provides 15.8 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

An illustration of the physical size and weight of the Canon T4i and the Panasonic G3 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.

The G3 can be obtained in four different colors (black, brown, red, white), while the T4i is only available in black.

Size Canon T4i vs Panasonic G3
Compare T4i versus G3 top
Comparison T4i or G3 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic G3 is notably smaller (27 percent) than the Canon T4i. Moreover, the G3 is substantially lighter (42 percent) than the T4i. In this context, it is worth noting that neither the T4i nor the G3 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (T4i) and the Micro Four Thirds Lens Catalog (G3). Mirrorless cameras, such as the G3, 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 T4i gets 440 shots out of its Canon LP-E8 battery, while the G3 can take 270 images on a single charge of its Panasonic DMW-BLD10 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The G3 was launched at a markedly lower price (by 29 percent) than the T4i, which puts it into a different 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.

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. 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 T4i features an APS-C sensor and the Panasonic G3 a Four Thirds sensor. The sensor area in the G3 is 32 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.0. The sensor in the T4i has a native 3:2 aspect ratio, while the one in the G3 offers a 4:3 aspect.

Canon T4i and Panasonic G3 sensor measures

With 17.9MP, the T4i offers a higher resolution than the G3 (15.8MP), but the T4i nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 3.77μm for the G3) due to its larger sensor. Moreover, the T4i is a somewhat more recent model (by 1 year) than the G3, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Canon T4i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T4i 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 Panasonic G3 are 23 x 17.2 inches or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inches or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inches or 38.9 x 29.2 cm for excellent quality prints.

The T4i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS Rebel T4i has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Panasonic Lumix DMC-G3 are ISO 160 to ISO 6400 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

T4i versus G3 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"). Of the two cameras under review, the T4i has a notably higher overall DXO score than the G3 (overall score 6 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.7 bits higher color depth, 0.6 EV in additional dynamic range, and 0.1 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the G3 provides a faster frame rate than the T4i. It can shoot movie footage at 1080/60i, while the Canon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the G3 has an electronic viewfinder (1440k dots), while the T4i has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the G3 offers a wider field of view (100%) than the one in the T4i (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the G3 has a higher magnification (0.70x vs 0.53x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon T4i and Panasonic G3 in connection with corresponding information for a sample of similar cameras.

It is notable that the T4i has a microphone port, which is missing on the G3. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Both the T4i and the G3 have been discontinued, but can regularly be found used on ebay. The G3 was replaced by the Panasonic G5, while the T4i was followed by the Canon T5i. Further information on the features and operation of the T4i and G3 can be found, respectively, in the Canon T4i Manual (free pdf) or the online Panasonic G3 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon T4i or the Panasonic G3 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the Canon EOS Rebel T4i:

  • More detail: Offers more megapixels (17.9 vs 15.8MP) with a 8% higher linear resolution.
  • Better image quality: Scores markedly higher (6 points) in the DXO overall assessment.
  • More dynamic range: Captures a larger spectrum of light and dark details (0.6 EV of extra DR).
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 460k dots).
  • Faster burst: Shoots at higher frequency (5 vs 4 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (440 versus 270) on a single battery charge.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Is somewhat more recent (announced 1 year after the G3).

ilogo

Advantages of the Panasonic Lumix DMC-G3:

  • Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.53x).
  • More compact: Is smaller (115x84mm vs 133x100mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 239g or 42 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • More affordable: Was introduced into a lower priced category (29 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in May 2011).

If the count of relative strengths (bullet points above) is taken as a measure, the T4i emerges as the winner of the contest (11 : 9 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 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.

T4i 11:09 G3

How about other alternatives? Do the specifications of the Canon T4i and the Panasonic G3 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the T4i or the G3. 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 where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], 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.

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

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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.
