Canon T3 vs Panasonic G2
The Canon EOS Rebel T3 (called Canon 1100D in some regions) and the Panasonic Lumix DMC-G2 are two digital cameras that were officially introduced, respectively, in February 2011 and March 2010. The T3 is a DSLR, while the G2 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (T3) and a Four Thirds (G2) sensor. The Canon has a resolution of 12.2 megapixels, whereas the Panasonic provides 12 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 T3 and the Panasonic Lumix DMC-G2? 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 T3 and the Panasonic G2 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 size dimensions are rounded to the nearest millimeter.
The G2 can be obtained in three different colors (black, blue, red), while the T3 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 Panasonic G2 is notably smaller (20 percent) than the Canon T3. Moreover, the G2 is markedly lighter (14 percent) than the T3. In this context, it is worth noting that neither the T3 nor the G2 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 (T3) and the Micro Four Thirds Lens Catalog (G2). Mirrorless cameras, such as the G2, 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.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The T3 was launched at a somewhat lower price (by 25 percent) than the G2, which makes it more attractive for photographers on a tight budget. 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.
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 T3 features an APS-C sensor and the Panasonic G2 a Four Thirds sensor. The sensor area in the G2 is 30 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 T3 has a native 3:2 aspect ratio, while the one in the G2 offers a 4:3 aspect.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 12.2MP, the T3 offers a slightly higher resolution than the G2 (12MP), but the T3 nevertheless has larger individual pixels (pixel pitch of 5.15μm versus 4.33μm for the G2) due to its larger sensor. Moreover, the T3 is a somewhat more recent model (by 11 months) than the G2, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The Canon EOS Rebel T3 has a native sensitivity range from ISO 100 to ISO 6400. The Panasonic Lumix DMC-G2 offers exactly the same ISO settings.
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 T3 has a notably higher overall DXO score than the G2 (overall score 9 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.7 bits higher color depth, 0.7 EV in additional dynamic range, and 0.6 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.
|Panasonic G2||Four Thirds||12.0||4000||3000||720/30p||21.2||10.3||493||53|
|Canon G1 X||1.5-inch||14.2||4352||3264||1080/24p||21.7||10.8||644||60|
|Panasonic G3||Four Thirds||15.8||4592||3448||1080/60i||21.0||10.6||667||56|
|Panasonic G10||Four Thirds||12.0||4000||3000||720/30p||21.2||10.1||411||52|
|Panasonic GH2||Four Thirds||15.9||4608||3456||1080/60i||21.2||11.3||655||60|

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (720/30p).
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G2 has an electronic viewfinder (1440k dots), while the T3 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 G2 offers a wider field of view (100%) than the one in the T3 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the G2 has a higher magnification (0.70x vs 0.50x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon T3 and Panasonic G2 along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G2 has a touchscreen, while the T3 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G2 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the T3 does not have a selfie-screen.
Concerning the storage of imaging data, both the T3 and the G2 write their files to SDXC cards.
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 EOS Rebel T3 and Panasonic Lumix DMC-G2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the T3 and the G2 have been discontinued, but can regularly be found used on eBay. The G2 was replaced by the Panasonic G3, while the T3 was followed by the Canon T5. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Panasonic websites.
So what is the bottom line? Which of the two cameras – the Canon T3 or the Panasonic G2 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Advantages of the Canon EOS Rebel T3:
- Better image quality: Scores markedly higher (9 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (0.7 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (0.6 stops ISO advantage).
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Faster burst: Shoots at higher frequency (3 vs 2.6 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (700 versus 360) on a single battery charge.
- More affordable: Was introduced into a lower priced segment (25 percent cheaper at launch).
- More modern: Is somewhat more recent (announced 11 months after the G2).
Arguments in favor of the Panasonic Lumix DMC-G2:
- 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 0.50x).
- Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (460k vs 230k dots).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- More compact: Is smaller (124x84mm vs 130x100mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 67g or 14 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- More heavily discounted: Has been on the market for longer (launched in March 2010).
If the count of relative strengths (bullet points above) is taken as a measure, the G2 is the clear winner of the contest (12 : 8 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.
How about other alternatives? Do the specifications of the Canon T3 and the Panasonic G2 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the T3 or the G2. 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 where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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, please note that some of the review sites have changed their methodology and reporting over time.
