The Pentax K-3 Mark II is Pentax's mid-range APS-C DSLR flagship (2015), rated at approximately 200,000 actuations. Shutter count is stored in the Pentax MakerNote of PEF RAW files and readable via ExifTool — PEF is not yet supported for direct browser-based reading in shuttercount.app.
Check Shutter Count →The Pentax K-3 Mark II (2015) builds on the original K-3 (2013) with the same 24.35 MP APS-C CMOS sensor but adds built-in GPS with AstroTracer support, an improved Real Resolution (Pixel Shift) system, and refined weather sealing. It features a 27-point AF system (25 cross-type), 8.3 fps burst, and 5-axis IBIS. The shutter is rated at approximately 200,000 actuations.

The K-3 Mark II shutter is rated at approximately 200,000 actuations. This is higher than most APS-C DSLRs (Canon 7D Mark II: 200,000; Nikon D500: 200,000; entry Nikons and Canons: 100,000).
Yes. Pentax stores the shutter count in a MakerNote tag within PEF files. ExifTool extracts it reliably with exiftool -ShutterCount file.PEF. If the seller shoots in DNG format, the Pentax MakerNote may not be preserved — request a PEF sample for verification.
The K-3 (2013) introduced the 24.35 MP sensor and AA filter simulator. The K-3 Mark II (2015) added built-in GPS with AstroTracer (previously only available via optional O-GPS1 accessory) and improved the Real Resolution system. The K-3 Mark III (2021) is a ground-up redesign: new 25.73 MP sensor, larger 100% OVF, significantly upgraded PDAF, and Astrotracer II — rated at ~300,000 actuations.
Check: IBIS/SR function (test at 1/10s), GPS lock and AstroTracer functionality, 82-point weather sealing gasket condition (especially port covers), dual SD card slot operation, battery health (D-LI90 or D-LI90P), optical viewfinder clarity, and sensor dust (shoot at f/16 against a bright sky). Also verify the built-in GPS acquires a signal before purchase.
Yes, for landscape, nature, and astrophotography. Its 24.35 MP sensor, class-leading weather sealing, built-in GPS/AstroTracer, and full compatibility with the legacy Pentax K-mount lens ecosystem make it a unique proposition. Used prices are very attractive. The lack of phase-detection video AF and 4K are its main limitations.
