Read the General ComparisonGeneralThe Canon EOS 77D and the Pentax K-S2 are both APS-C DSLRs, but they lead into different lens systems. The 2017 77D uses the Canon EF-S mount, while the 2015 K-S2 uses the Pentax KAF2 mount, shaping every future lens purchase. Both use an APS-C CMOS sensor, so lenses frame the same way on either body. The bodies measure differently: 131 x 100 x 76 mm and 765 g for the 77D against 91 x 123 x 73 mm and 678 g for the K-S2. | ||

Read the Optics ComparisonOpticsThe 77D is the stronger choice for heavy cropping, with 24.2 megapixels against 20 on the K-S2, useful when a distant bird fills only part of the frame. Its 45 autofocus points give more placement options than the K-S2's 11, and its 6 fps maximum burst edges the K-S2's 5.4 fps. The K-S2 answers with in-body stabilisation, steadying handheld shots with unstabilised lenses, which the 77D lacks. It also reaches 1/6000 second rather than 1/4000 for shorter exposures, and it views through a pentaprism rather than the 77D's pentamirror. Both start at 100 ISO, and the K-S2's native ceiling is 51200 ISO against the 77D's 25600. | ||

Read the Video ComparisonVideoFor HD video both cameras offer the same limits, Full HD maximum resolution and a 60 fps top frame rate, for family clips and slowed-down action. Each also has a built-in interval timer for timelapse sequences. The practical difference is file handling. The 77D records in MOV and MP4, while the K-S2 records in MPEG-4 and MOV, so match the camera to your workflow. If you need 4K, neither provides it. | ||

Read the Features ComparisonFeaturesThe K-S2 is the better pick for shooting outdoors in poor weather, with weather sealing the 77D lacks, plus built-in GPS that tags travel photos with location data. The 77D counters with a touchscreen on its 3-inch LCD, which speeds focus placement and menu changes, while the K-S2 screen is not touch-sensitive. The 77D screen also shows finer detail, with 1,040,000 dots against 921,000. They share useful features: both have Wi-Fi and Bluetooth for wireless transfer, a flip-out screen for waist-level work, live view, and built-in and external flash support. | ||

Read the Storage & battery ComparisonStorage and BatteryStorage is a similarity: both write to a single SD, SDHC or SDXC card with UHS-I support, and neither offers a second slot. Battery life differs, with the 77D rated at 600 shots on its LP-E17 against 410 shots on the K-S2's D-LI109. Neither charges its battery over USB, so both need a separate charger or a spare battery. | ||

Read: Verdict
Verdict
Choose the Canon EOS 77D for sports, wildlife and heavy cropping. Its 45 autofocus points give many more placement options than the K-S2's 11, and 24.2 megapixels leave room to crop distant animals. Its battery is rated for 600 shots against the K-S2's 410.
Choose the Pentax K-S2 if you shoot in rain or dust. Its in-body stabilisation steadies handheld shots with any mounted lens, and built-in GPS tags travel photos with location data. Where video, Wi-Fi and the SD slot match, neither gains an edge, so your lens system should decide.
