Canon XTi vs Panasonic GF1
The Canon EOS Rebel XTi (called Canon 400D in some regions) and the Panasonic Lumix DMC-GF1 are two digital cameras that were announced, respectively, in August 2006 and September 2009. The XTi is a DSLR, while the GF1 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (XTi) and a Four Thirds (GF1) sensor. The Canon has a resolution of 10.1 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 XTi and the Panasonic Lumix DMC-GF1? 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 XTi and the Panasonic GF1. 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 dimensions are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GF1 is notably smaller (21 percent) than the Canon XTi. Moreover, the GF1 is markedly lighter (31 percent) than the XTi. In this context, it is worth noting that neither the XTi nor the GF1 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 (XTi) and the Micro Four Thirds Lens Catalog (GF1). Mirrorless cameras, such as the GF1, 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. 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 GF1 was somewhat cheaper (by 6 percent) than the XTi at launch, but both cameras fall into the same price category. 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.
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 XTi features an APS-C sensor and the Panasonic GF1 a Four Thirds sensor. The sensor area in the GF1 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 XTi has a native 3:2 aspect ratio, while the one in the GF1 offers a 4:3 aspect.
Despite having a smaller sensor, the GF1 offers a higher resolution of 12 megapixels, compared with 10.1 MP of the XTi. 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 4.33μm versus 5.71μm for the XTi). However, it should be noted that the GF1 is much more recent (by 3 years) than the XTi, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Panasonic GF1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GF1 for good quality output (200 dots per inch) amounts to 20 x 15 inches or 50.8 x 38.1 cm, for very good quality (250 dpi) 16 x 12 inches or 40.6 x 30.5 cm, and for excellent quality (300 dpi) 13.3 x 10 inches or 33.9 x 25.4 cm. The corresponding values for the Canon XTi are 19.4 x 13 inches or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inches or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inches or 32.9 x 21.9 cm for excellent quality prints.
The Canon EOS Rebel XTi has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Panasonic Lumix DMC-GF1 are ISO 100 to ISO 3200 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 XTi has a notably higher overall DXO score than the GF1 (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.9 bits higher color depth, 0.7 EV in additional dynamic range, and 0.4 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.

Many modern cameras cannot only take still pictures, but also record videos. The GF1 indeed provides for movie recording, while the XTi does not. The highest resolution format that the GF1 can use is 720/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the XTi has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GF1 relies on live view and the rear LCD for framing. That said, the GF1 can be equipped with an optional viewfinder – the DMW-LVF1. The following table reports on some other key feature differences and similarities of the Canon XTi, the Panasonic GF1, and comparable cameras.
The XTi writes its imaging data to Compact Flash cards, while the GF1 uses SDHC 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 XTi and Panasonic Lumix DMC-GF1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the XTi and the GF1 have been discontinued, but can regularly be found used on eBay. The XTi was replaced by the Canon Xsi, while the GF1 was followed by the Panasonic DMC-GF2. 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? Is the Canon XTi better than the Panasonic GF1 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon EOS Rebel XTi:
- Better image quality: Scores markedly higher (8 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 (0.4 stops ISO advantage).
- Easier framing: Has an optical viewfinder for image composition and settings control.
- More heavily discounted: Has been available for much longer (launched in August 2006).
Reasons to prefer the Panasonic Lumix DMC-GF1:
- More detail: Has more megapixels (12 vs 10.1MP), which boosts linear resolution by 7%.
- Broader imaging potential: Can capture not only stills but also 720/30p video.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (460k vs 230k dots).
- More compact: Is smaller (119x71mm vs 127x84mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 171g or 31 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- More modern: Reflects 3 years of technical progress since the XTi launch.
If the number of relative strengths (bullet points above) is taken as a guide, the GF1 emerges as the winner of the match-up (8 : 5 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.
How about other alternatives? Do the specifications of the Canon XTi and the Panasonic GF1 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 incomplete and does no justice, for example, to the way the XTi or the GF1 perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
