  • Fixed, single focal length lens; Poor battery life; No built-in flash; No touchscreen LCD; Slow buffer clearing; No 4K video; Expensive.

  • Bulkier than APS-C DSLRs; Top ISOs are for the spec sheet, not the real world; JPEGs are a bit punchy by default; Slow startup; Below-average battery life; Only a relatively modest update to the K-1.
