Canon EOS Rebel T5i: Lab Test Results & Comments
There are some minor enhancements of the body and design. The T5i has a different finish and a new surface material, which allows for better and more comfortable handling. All settings on the top mode dial are now allocated to different functions. The image processor has a slightly changed “bias,” which causes some differences compared to the test images of the T4i; for example, sharpness and color are a bit more intensified.
The camera offers all standard exposure modes, like P, Tv, Av, and M. It also offers the four most important scene modes (portrait, landscape, macro, and sport) on the mode dial, plus additional scene modes in the menu revealed when the dial is set to “SCENE.” In addition, it offers iA mode, which detects the “necessary” scene mode automatically.
The camera is able to record Full HD video with different frame rate settings such as 24, 25, and 30 fps. It allows the user to change exposure settings in video mode and to set up the sound level manually. A microphone jack allows for use of external stereo microphones to enhance sound quality. When used in combination with Canon STM lenses the camera is able to focus very quickly, continuously, and silently, even while recording video.
Color: The camera reproduced “live” test images and the test charts with natural-looking colors. Just like nearly all Canon cameras, it showed some enhanced skin tones (with a slightly higher magenta rate) and high average saturation (108 percent).
The automatic white balance system showed a slight tendency toward cooler colored areas. The standard test box shot shows this very slight shift in gray areas. The shift is also visible in the bright background in our portrait shot. The red nuances of the T-shirt are boosted quite highly, although it should be stated that the level of color errors is very low.
Sharpness: The camera showed a very good performance in our resolution tests and reproduced the ISO 12.233 chart with 3149 lines in picture height (nominal sensor resolution in picture height: 3456). The T5i enhances image sharpness by an intense filtering when creating JPEGs. The result chart showed a clearly visible overshot effect (20.5 percent) and the graph for the black-and-white contrast transition showed clearly visible peaks caused by that artificial sharpness effect.
These oversharpened elements are also visible in the standard test box shot. This may cause an artificial look in fine details, like in the hair of the model in the portrait shot and in other real-life images. The differentiation of red colors could be better, caused by the high saturation of red nuances.
Noise: The new Canon offers silky smooth images even at higher ISO speed settings. Luminance noise stays on a good/low level in images taken with ISO 100 to ISO 1600, while color noise is filtered out in a very efficient way. Color clouds in homogeneous-colored areas are noticeable in images taken with ISO 3200 and higher. This color noise is clearly visible in images taken with ISO 6400, but they are reduced in the highest ISO speed setting of 12,800. Atthis high ISO setting the anti-noise filtering gets very intense and reduces color clouds, but in return it also reduces image details and creates typical anti-noise filtering artifacts.
The dynamic range results are very good for a camera with an APS-C-sized sensor, with a maximum of 11.7 f/stops and even high results (more than 10 f/stops) in images shot with higher ISO speed settings (up to ISO 800). When using higher ISO settings greater than ISO 1600 the dynamic range results decline.
