Read the Optics ComparisonOpticsBoth use 24 MP APS-C CMOS sensors, so large prints and heavy crops have the same pixel count to draw on. The Rebel T7i takes Canon EF and EF-S lenses, while the KF uses the Pentax KAF2 mount, so existing glass may settle the choice before the bodies do. For handheld work the KF is the stronger choice, offering in-body stabilisation the Rebel T7i lacks, which steadies any mounted lens at slower shutter speeds. The Canon answers with 45 autofocus points against 11 for tracking a moving subject. The KF reaches 1/6000 second against 1/4000, a shorter exposure for wide apertures in bright light. Its viewfinder is a pentaprism, the Canon's a pentamirror. | ||

Read the Video ComparisonVideoFull HD at up to 60 frames per second is the shared recording limit, enough for family clips and simple half-speed slow motion. Both record in MPEG-4 or MOV files, and neither offers 4K. The practical split is timelapse. The Rebel T7i has a built-in interval feature for sequences like clouds crossing a landscape, without external gear. The KF does not, so sequences need manual triggering or a separate remote. | ||

Read the Features ComparisonFeaturesWeather sealing is the KF's headline advantage for beach outings, drizzle and dusty trails, and the Rebel T7i is not sealed. GPS tags files with shooting locations on both cameras. Each also has a 3-inch articulating TFT screen, a built-in flash and external flash support. The Canon wins the workflow side. Its touch screen allows quick focus-point taps and menu swipes, and Wi-Fi and Bluetooth send photos straight to a phone. The KF has neither wireless option nor touch control. | ||

Read the Storage & battery ComparisonStorage and BatteryThe storage choices match: both bodies take a single SD, SDHC or SDXC card at UHS-I speed, so cards and readers carry over between them. Neither has a second slot, so a spare card matters on long shoots. Battery life favours the Canon, rated at 600 shots against 410 on the KF. The Pentax partly offsets this with USB charging, so a power bank can top up its D-LI109 pack between locations, while the Canon's LP-E17 battery has no USB charging. | ||

Read: Verdict
Verdict
Choose the Pentax KF if you shoot outdoors in changeable weather or handheld in dim rooms, for its weather sealing and in-body stabilisation. Its ISO range also reaches 102400 in very dark scenes.
Choose the Canon EOS Rebel T7i / 800D for people and action photography, where 45 autofocus points spread across the frame, and for touch control and instant phone transfer over Wi-Fi and Bluetooth. Existing Canon EF or EF-S lenses are a strong reason to stay with that mount.
