CANON EOS REBEL T3I BEST BUY ISO

With an ISO rating up to 6400 (expandable to ISO 12800), along with the DIGIC 4 Image Processor's improved noise-reduction technology, creative possibilities abound. Amazing Results, No Matter the Light.The EOS Rebel T3i features an expanded ISO range that makes shooting possible in situations previously unthinkable without flash.It works in concert with the EOS Rebel T3i DSLR's CMOS Image Sensor to achieve phenomenal levels of performance in nearly any situation. Besides, the Canon DIGIC 4 Image Processor dramatically speeds up the entire EOS Rebel T3i DSLR's camera operations for intuitive operation and offers improvements in both fine detail and natural color reproduction. Its APS-C size sensor creates an effective 1.6x field of view (compared to 35mm format).

This first-class sensor features many of the same new technologies as used by professional Canon cameras to maximize each pixel's light-gathering efficiency. High image quality and speedThe EOS Rebel T3i has an 18.0 Megapixel CMOS (Complementary Metal Oxide Semiconductor) sensor that captures images with exceptional clarity and tonal range and offers more than enough resolution for big enlargements or crops.The Canon Rebel T3i's flash took an average of 3.2 seconds to recharge after a full-power discharge, which is pretty fast. This gives us worst-case buffer capacity numbers: You're likely to see greater buffer capacity when shooting more normal subjects.) (Note that in our cycle time testing we shoot a target consisting of a fine-grained digital noise pattern, designed to be very hard to compress. Measured buffer depths in continuous mode were low at 9 frames for large/fine JPEGs, 5 frames for RAW mode and only 3 frames for RAW+ L/F JPEG. Shot-to-shot cycle times in the Canon T3i's single-shot mode were about average for an SLR, at 0.44 second for large/fine JPEGs, 0.46 second for RAW and 0.39 second for RAW + large/fine JPEGs.Ĭontinuous mode speeds are also about average for a consumer model, at about 3.6 frames-per-second for large/fine JPEGs or RAWs, and 3.3 frames-per-second for RAW + large/fine JPEGs. ISO sensitivity and noise reduction settings can also affect cycle times and burst mode performance. Slow cards may also limit length of bursts in continuous mode. Slower cards will produce correspondingly slower clearing times. *Note: Buffer clearing times measured with a SanDisk Extreme III 30MB/sec 8GB SDHC card. Being an older design with a non-ultrasonic motor, it wouldn't be the fastest at slewing from one focus setting to another, but that's exactly the reason we measure focus determination speed, which is primarily a function of the camera body, vs focus adjustment speed, which is primarily a function of the lens. We also use the same Sigma 70mm f/2.8 macro with every camera (on all platforms except Four Thirds/Micro Four Thirds and Nikon consumer models lacking an in-body focus motor), to further reduce variation, and because our tests showed that focus-determination time with this lens was close to the fastest, across multiple camera bodies from different manufacturers. To minimize the effect of different lens' focusing speed, we test AF-active shutter lag with the lens already set to the correct focal distance. Prefocused, the Canon Rebel T3i's shutter lag was pretty fast in Live View mode, at 0.084 second. Surprisingly, Live Mode (contrast-detect) AF was faster at 0.826 second, but keep in mind we don't defocus the lens between trials, so phase-detect AF will likely be faster in most real-world situations. We measured 1.176 seconds using "Quick Mode" (phase-detect AF) which is a bit slow for PD AF. The Canon Rebel T3i's AF lag time in Live View mode was longer than using the optical viewfinder (as expected). In Continuous focus mode, shutter lag was 0.129 second, very good.

Shutter lag in Manual focus was a bit slower than prefocused, at 0.114 second, which is still quite fast.

(The camera emits flash metering pulses and analyses the results before taking the final flash exposure.) "Prefocusing" the camera by half-pressing and holding down the shutter button before the final exposure resulted in a lag time of only 0.087 second which is good for a consumer SLR.

As expected, enabling the built-in flash increased full AF lag a bit, to 0.260 second. Interestingly, switching to Auto Selection AF and allowing the camera to choose the focus point reduced shutter lag to 0.160 second, which is very good. The Canon Rebel T3i's full autofocus shutter response was a touch slow using our standard single-point AF test, at 0.283 second. Time to capture, after half-pressing and holding shutter button.
