Canon T3i vs Sony A99 II

The Canon EOS Rebel T3i (called Canon 600D in some regions) and the Sony Alpha ALT-A99 II are two digital cameras that were announced, respectively, in February 2011 and September 2016. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (T3i) and a full frame (A99 II) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Sony provides 42.2 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 T3i and the Sony Alpha ALT-A99 II? 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.

Body comparison

The physical size and weight of the Canon T3i and the Sony A99 II 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 width, height and depth measures are rounded to the nearest millimeter.

Size Canon T3i vs Sony A99 II
Compare T3i versus A99 II top
Comparison T3i or A99 II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A99 II is notably larger (12 percent) than the Canon T3i. Moreover, the A99 II is substantially heavier (49 percent) than the T3i. It is noteworthy in this context that the A99 II is splash and dust-proof, while the T3i does not feature any corresponding weather-sealing.

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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the T3i gets 440 shots out of its LP-E8 battery, while the A99 II can take 490 images on a single charge of its NP-FM500H power pack.

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

Any camera decision will obviously take relative prices into account. 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 T3i was launched at a markedly lower price (by 81 percent) than the A99 II, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon T3i features an APS-C sensor and the Sony A99 II a full frame sensor. The sensor area in the A99 II is 160 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon T3i and Sony A99 II sensor measures

With 42.2MP, the A99 II offers a higher resolution than the T3i (17.9MP), but the A99 II nevertheless has larger individual pixels (pixel pitch of 4.52μm versus 4.31μm for the T3i) due to its larger sensor. Moreover, the A99 II is a much more recent model (by 5 years and 7 months) than the T3i, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the A99 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony A99 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A99 II for good quality output (200 dots per inch) amounts to 39.8 x 26.5 inches or 101 x 67.4 cm, for very good quality (250 dpi) 31.8 x 21.2 inches or 80.8 x 53.9 cm, and for excellent quality (300 dpi) 26.5 x 17.7 inches or 67.3 x 44.9 cm. The corresponding values for the Canon T3i are 25.9 x 17.3 inches or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inches or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inches or 43.9 x 29.3 cm for excellent quality prints.

The A99 II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS Rebel T3i has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Sony Alpha ALT-A99 II are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-25600.

T3i versus A99 II 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 consideration, the A99 II offers substantially better image quality than the T3i (overall score 27 points higher). The advantage is based on 3.3 bits higher color depth, 1.9 EV in additional dynamic range, and 1.5 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.

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 A99 II provides a better video resolution than the T3i. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A99 II has an electronic viewfinder (2400k dots), while the T3i 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 A99 II offers a wider field of view (100%) than the one in the T3i (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the A99 II has a higher magnification (0.78x 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 T3i and Sony A99 II in connection with corresponding information for a sample of similar cameras.

Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The T3i has one, while the A99 II does not. While the built-in flash of the T3i is not very powerful, it can at times be useful as a fill-in light.

Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.

The T3i writes its imaging data to SDXC cards, while the A99 II uses SDXC or Memory Stick PRO Duo cards. The A99 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the T3i only has one slot. The A99 II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the T3i cannot take advantage of Ultra High Speed SD cards.

Connectivity comparison

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 T3i and Sony Alpha ALT-A99 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A99 II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the T3i does not provide wifi capability.

Studio photographers will appreciate that the Sony A99 II (unlike the T3i) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The A99 II is a recent model that features in the current product line-up of Sony. In contrast, the T3i has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the T3i was succeeded by the Canon T4i. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Sony websites.

Review summary

So what is the bottom line? Which of the two cameras – the Canon T3i or the Sony A99 II – 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.

If the count of relative strengths (bullet points above) is taken as a measure, the A99 II is the clear winner of the contest (26 : 7 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 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.

T3i 07:26 A99 II

How about other alternatives? Do the specifications of the Canon T3i and the Sony A99 II place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing 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 T3i or the A99 II perform in practice. 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.

Expert reviews

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.

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

The review scores listed above should be treated 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 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.
