Read the Optics ComparisonOpticsThe Sony SLT Alpha 68 is the stronger choice for moving subjects, pairing an 8 fps burst with 79 autofocus points against 5.4 fps and 11 points on the Pentax K-S1. Wider coverage gives you more focus-point placement on an off-centre subject. Its 24 MP sensor offers 19.3 percent more pixels than the K-S1's 20.12 MP, leaving more room to crop a distant bird. Each body brings a different native lens system: the K-S1 uses the Pentax KAF mount, the Alpha 68 the Sony Alpha DT mount. Both share an APS-C CMOS sensor format and in-body stabilisation, which lets any lens be handheld at slower shutter speeds. The viewfinders split the choice, with the K-S1's optical pentaprism showing no lag and the Alpha 68's 1440000-dot electronic finder previewing exposure before capture. | ||

Read the Video ComparisonVideoThe Alpha 68 gives you twice the slow-motion room, with a maximum frame rate of 60 fps against 30 fps on the K-S1. A sprinting athlete or a bird taking off plays back at half speed when 60 fps footage is shown at 30. Both cap video resolution at Full HD, so neither is a 4K tool. File formats also differ in how they fit an editing workflow. The Alpha 68 offers XAVC S, AVCHD Ver. 2.0 and MP4, while the K-S1 records MOV and AVI. | ||

Read the Features ComparisonFeaturesScreen handling favours the Alpha 68 for awkward angles, because its 2.7-inch LCD tilts for waist-level or tripod framing while the K-S1's 3-inch screen is fixed. The K-S1 answers with a sharper display for reviewing focus and detail, at 921000 dots against 460800 on the Sony. Flash and live view are shared ground. Both include a built-in flash, support an external flash and offer live view. Neither has touch control, Wi-Fi, Bluetooth, GPS or weather sealing. | ||

Read: Verdict
Verdict
For sports, wildlife and children, the Sony SLT Alpha 68 is the better pick. Its 79 autofocus points and 8 fps burst serve action, the 60 fps maximum frame rate opens up slow motion, and the tilting screen helps at waist level. The 580-shot rating and exposure-previewing viewfinder suit long shooting days.
Choose the Pentax K-S1 for its lag-free optical pentaprism finder, or the smaller 558 g body when travel weight matters. Its 1/6000 second top shutter speed permits shorter exposures than the Alpha 68's 1/4000, useful for wide-aperture daylight work.
