Ordinance EOS Rebel Ti versus Ti key contrasts TechRadar

“Canonu2019s new EOS Rebel T7i (known as the EOS 800D outside the US) seeks to up the bar for the upper-entry-level DSLR category, and updates the popular EOS Rebel T6i (EOS 750D) thatu2019s just reached its second birthday.
While the EOS Rebel T7i shares much the same intentions as the T6i, and soldiers on with much of the same tech, Canon has made a number of changes across the spec sheet to make it more appealing to the first-time user u2013 some of which were first included inside more premium EOS models.
We’ve rifled through the spec sheet to find out exactly what Canon has done to separate the new camera from its predecessor. Hereu2019s a rundown of the main changes between the two.
1. Latest DIGIC 7 processor
While the EOS Rebel T6i / EOS 750D employed Canonu2019s DIGIC 6 processing engine, the latest EOS Rebel T7i / EOS 800D welcomes the newer DIGIC 7 version. This first surfaced inside the PowerShot G7 X Mark II model released last year before being included inside the more recent EOS M5 and PowerShot G9 X II.
Compared with previous engines, this is said to provide superior image processing and faster operation, and it also helps to boost burst speeds (more on this later).
2. Revised sensor
With the same 24.2MP pixel count as the EOS Rebel T6i, the sensor inside the EOS Rebel T7i appears to be unchanged at first glance. The spec sheet, however, reveals it to have a different total pixel count of 25.80MP (vs 24.7MP).
This is the same total pixel count as the sensor inside the EOS 80D, which was newly developed for that model. Canon claims the two share the same technology here, so we should expect to see an improvement over the previous 24.2MP version.
3. Expanded ISO Range
No doubt a consequence of the revised processor and sensor partnership, the new model features a slightly broader ISO range than before. Where the EOS Rebel T6i could be adjusted over a range of ISO100-12,800 as standard, the new model adds a stop at the latter end to create a native range of ISO 100-25,600.
Similarly, the expanded sensitivity option at the higher end of the scale has now changed from a setting equivalent to ISO25,600 on the EOS Rebel T6i to one equivalent to ISO51,200 on the EOS Rebel T7i.
A more minor change is that, when capturing stills, the entire ISO100-25,600 native range can now be accessed when the camera is set to the Auto ISO setting; previously this was limited to ISO100-6400. When shooting videos, this contracts to an ISO100-12,800 range.
4. New 18-55mm kit lens
Both the EOS Rebel T7i / EOS 800D and EOS 77D are released alongside a new EF-S 18-55mm f/4-5.6 IS STM kit lens, which Canon claims is the smallest non-retractable DSLR kit lens of its focal range.
Weighing 215g, the lens incorporates a four-stop Image Stabilizer to help maintain sharpness in images, as well as Canonu2019s STM technology, which promises discreet performance when capturing movies.”
