Review Excerpt

Very good image quality and excellent high ISO performance. Premium build quality. In-body image stabilization. Lots of creative features. Full HD movie capture with manual exposure control.
Barely any smaller than a standard SLR, but lacks viewfinder and phase-detect autofocus. Contrast-detect AF is slow and unreliable. Body design is clumsy and uncomfortable. Very slow raw burst shooting.
Read our Pentax K-01 Review

Excellent video quality; Very good high ISO performance; Cinema 4K & UHD video up to 60p; Full HD up to 240p; 10-bit internal video recording; Tons of features & options for advanced/pro videographers.
10MP resolution is limiting for still photos; No in-body image stabilization; Slower AF than GH5; Buffer clearing could be faster; No 6K Photo features due to sensor resolution.
