Canon G15 vs T1i
The Canon PowerShot G15 and the Canon EOS Rebel T1i (labelled Canon 500D in some countries) are two digital cameras that were revealed to the public, respectively, in September 2012 and March 2009. The G15 is a fixed lens compact, while the T1i is a DSLR. The cameras are based on a 1/1.7-inch (G15) and an APS-C (T1i) sensor. The G15 has a resolution of 12 megapixels, whereas the T1i provides 15.1 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 PowerShot G15 and the Canon EOS Rebel T1i? 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.
An illustration of the physical size and weight of the Canon G15 and the Canon T1i 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon T1i is considerably larger (55 percent) than the Canon G15. In this context, it is worth noting that neither the G15 nor the T1i are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G15 has a lens built in, whereas the T1i is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the T1i and their specifications in the Canon EF Lens Catalog.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G15 was launched at a lower price than the T1i, despite having a lens built in. 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 sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the 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 G15 features a 1/1.7-inch sensor and the Canon T1i an APS-C sensor. The sensor area in the T1i is 672 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.6 and 1.6. The sensor in the G15 has a native 4:3 aspect ratio, while the one in the T1i offers a 3:2 aspect.
In terms of chip-set technology, the G15 uses a more advanced image processing engine (DIGIC 5) than the T1i (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.
With 15.1MP, the T1i offers a higher resolution than the G15 (12MP), but the T1i nevertheless has larger individual pixels (pixel pitch of 4.69μm versus 1.89μm for the G15) due to its larger sensor. However, the G15 is a much more recent model (by 3 years and 5 months) than the T1i, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Canon T1i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T1i for good quality output (200 dots per inch) amounts to 23.8 x 15.8 inches or 60.4 x 40.2 cm, for very good quality (250 dpi) 19 x 12.7 inches or 48.3 x 32.2 cm, and for excellent quality (300 dpi) 15.8 x 10.6 inches or 40.2 x 26.8 cm. The corresponding values for the Canon G15 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.
The Canon PowerShot G15 has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Canon EOS Rebel T1i are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.
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.
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 consideration, the T1i offers substantially better image quality than the G15 (overall score 17 points higher). The advantage is based on 1.8 bits higher color depth, and 2 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.
|Note: DXO values in italics represent estimates based on sensor size and age.|
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, but the G15 provides a higher frame rate than the T1i. It can shoot video footage at 1080/24p, while the T1i is limited to 1080/20p.
Beyond body and sensor, cameras can and do differ across a range of features. The G15 and the T1i 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 following table reports on some other key feature differences and similarities of the Canon G15, the Canon T1i, and comparable cameras.

Both the G15 and the T1i have been discontinued, but can regularly be found used on ebay. The T1i was replaced by the Canon T2i, while the G15 was followed by the Canon G16. Further information on the features and operation of the G15 and T1i can be found, respectively, in the Canon G15 Manual (free pdf) or the online Canon T1i Manual.
So how do things add up? Which of the two cameras – the Canon G15 or the Canon T1i – 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.
Arguments in favor of the Canon PowerShot G15:
- Better jpgs: Has a more modern image processing engine (DIGIC 5 vs DIGIC 4).
- Better video: Provides higher movie framerates (1080/24p versus 1080/20p).
- Ready to shoot: Comes with a built-in lens, while the T1i requires a separate lens.
- More compact: Is smaller (107x76mm vs 129x98mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the T1i).
- Sharper images: Has hand-shake reducing image stabilization built-in.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Reflects 3 years and 5 months of technical progress since the T1i launch.
Reasons to prefer the Canon EOS Rebel T1i:
- More detail: Has more megapixels (15.1 vs 12MP), which boosts linear resolution by 14%.
- Better image quality: Scores substantially higher (17 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.8 bits more color depth).
- Better low-light sensitivity: Can shoot in dim conditions (2 stops ISO advantage).
- Faster burst: Shoots at higher frequency (3.4 vs 2.1 flaps/sec) to capture the decisive moment.
- More flexible: Makes it possible to change lenses and thus to use specialty optics.
- Longer lasting: Gets more shots (400 versus 350) out of a single battery charge.
- More heavily discounted: Has been around for much longer (launched in March 2009).
If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (8 points each). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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 G15 and the Canon T1i place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best DSLR 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 G15 or the T1i. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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 review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
