Canon T3 vs Panasonic GH1
The Canon EOS Rebel T3 (called Canon 1100D in some regions) and the Panasonic Lumix DMC-GH1 are two digital cameras that were officially introduced, respectively, in February 2011 and March 2009. The T3 is a DSLR, while the GH1 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (T3) and a Four Thirds (GH1) 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-GH1? 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 side-by-side display below illustrates the physical size and weight of the Canon T3 and the Panasonic GH1. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.
The GH1 can be obtained in two different colors (black, 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 GH1 is notably smaller (14 percent) than the Canon T3. Moreover, the GH1 is markedly lighter (22 percent) than the T3. In this context, it is worth noting that neither the T3 nor the GH1 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 (GH1). Mirrorless cameras, such as the GH1, 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. 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.

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 T3 was launched at a markedly lower price (by 50 percent) than the GH1, which puts it into a different market segment. 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 more expensive and 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 GH1 a Four Thirds sensor. The sensor area in the GH1 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 GH1 offers a 4:3 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 12.2MP, the T3 offers a slightly higher resolution than the GH1 (12MP), but the T3 nevertheless has larger individual pixels (pixel pitch of 5.15μm versus 4.33μm for the GH1) due to its larger sensor. Moreover, the T3 is a somewhat more recent model (by 1 year and 11 months) than the GH1, 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 corresponding ISO settings for the Panasonic Lumix DMC-GH1 are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the GH1 provides a better video resolution than the T3. It can shoot movie footage at 1080/24p, while the Canon is limited to 720/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the GH1 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 GH1 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 GH1 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 table below summarizes some of the other core capabilities of the Canon T3 and Panasonic GH1 in connection with corresponding information for a sample of similar cameras.

It is notable that the GH1 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The T3 does not feature such a mic input.
Both the T3 and the GH1 have been discontinued, but can regularly be found used on eBay. The GH1 was replaced by the Panasonic GH2, 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 conclusions can be drawn? Is the Canon T3 better than the Panasonic GH1 or vice versa? The listing below highlights the relative strengths of the two models.
Advantages of the Canon EOS Rebel T3:
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Longer lasting: Can take more shots (700 versus 300) on a single battery charge.
- More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
- More modern: Is somewhat more recent (announced 1 year and 11 months after the GH1).
Reasons to prefer the Panasonic Lumix DMC-GH1:
- More dynamic range: Captures a broader range of light and dark details (0.6 EV of extra DR).
- Better video: Provides higher definition movie capture (1080/24p vs 720/30p).
- Better sound: Can connect to an external microphone for higher quality sound recording.
- 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.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- More compact: Is smaller (124x90mm vs 130x100mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 110g or 22 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 2009).
If the number of relative strengths (bullet points above) is taken as a guide, the GH1 is the clear winner of the contest (14 : 4 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 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 GH1 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 incomplete and does no justice, for example, to the way the T3 or the GH1 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.
This is why hands-on reviews by experts 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], 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.

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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
