Read the General ComparisonGeneralThe Canon EOS Rebel T7i / 800D is the lighter body for everyday APS-C shooting, while the Pentax K-S2 is the weather-sealed option with a pentaprism viewfinder. Both are DSLRs built around a single native lens system, Canon EF/EF-S for the T7i and Pentax KAF2 for the K-S2. The 2017 Canon weighs 532 g against 678 g for the 2015 Pentax, a 146 g difference between the two bodies. | ||

Read the Optics ComparisonOpticsThe T7i is the stronger choice for fast-moving subjects, pairing 45 autofocus points with a 6 fps burst against 11 points and 5.4 fps on the K-S2. That wider AF spread helps keep a running child or flying bird framed as it crosses the frame, and the extra frames per second give you more keepers from each burst. The K-S2 answers with in-body stabilisation, which steadies handheld shots at slower shutter speeds with any mounted lens. Its 1/6000 second top shutter also permits shorter exposures than the T7i's 1/4000 second for wide apertures in bright light. For heavy cropping the T7i leads, offering 24 MP against the K-S2's 20 MP. | ||

Read the Features ComparisonFeaturesThe T7i's touch screen makes it the quicker camera to operate, letting you tap to set focus or swipe through menus like a phone. Its 1,040,000-dot display also resolves finer detail than the K-S2's 921,000-dot screen when reviewing focus on location. The K-S2's weather sealing is its standout feature, protecting the body against dust and moisture in conditions the T7i cannot match. Both share a 3-inch articulating screen for waist-level and overhead framing, live view and built-in flash, and both offer GPS tagging plus Wi-Fi and Bluetooth transfer. | ||

Read the Storage & battery ComparisonStorage and BatteryThe T7i's 600-shot rating outlasts the K-S2's 410 shots under their respective test conditions, making it the better pick for a day away from a charger. Each uses its own pack, the Canon LP-E17 and the Pentax D-LI109, and neither charges over USB. Storage is a similarity between them. Each takes a single SD, SDHC or SDXC card with UHS-I support, so fast cards for burst shooting work in either body, and neither offers a second slot for overflow. | ||

Read: Verdict
Verdict
Choose the Canon EOS Rebel T7i / 800D for action, wildlife and travel: 45 AF points and 6 fps bursts keep up with fast subjects, and 24 MP leaves more room to crop a distant animal. It is also the lighter body at 532 g.
Choose the Pentax K-S2 for shooting outdoors in poor weather or handheld in dim light, because its weather sealing, in-body stabilisation and pentaprism viewfinder serve those situations, and its 1/6000 second shutter suits wide apertures in sunshine. Both offer Full HD video, GPS tagging and wireless transfer, so the choice rests on how you shoot stills.
