Ricoh K-S1

Quick view

The Ricoh K-S1 is a mid-range digital single-lens reflex (DSLR) camera released in 2013, featuring a 16.2-megapixel APS-C CMOS sensor. This sensor size offers a balance between image quality and portability while supporting a rich color depth and dynamic range. It is powered by the PRIMEII image processing engine which ensures swift operation and noise reduction in high ISO settings. The camera supports an ISO sensitivity range from 100 to 25600, allowing flexibility in various lighting conditions. Autofocus is facilitated by an 11-point AF system that balances speed and precision for diverse photographic environments. Additionally, the K-S1 includes 1080p Full HD video recording capabilities, with manual controls available for more advanced videography.

The camera operates with a pentamirror viewfinder providing approximately 95% coverage, ideal for framing shots accurately. It features a 3.0-inch vari-angle LCD screen with 921,000 dots resolution for composing images at different angles and reviewing captured content. The camera supports SD, SDHC, and SDXC memory cards for storage and includes built-in flash and hot shoe for external flash units. Its body incorporates weather-sealing elements for increased durability against dust and moisture, enhancing reliability in challenging environments.

The Ricoh K-S1 offers excellent image quality with its APS-C CMOS sensor and PRIMEII processor. Its compact and lightweight design makes it comfortable for extended handheld shooting sessions. The camera's high ISO performance allows shooting in low-light conditions with reduced noise. The vari-angle LCD provides flexibility in framing, especially for video and unusual angles. Its 11-point autofocus system helps capture sharp images rapidly. Weather-sealing increases durability for outdoor photography in varied weather conditions.

Despite its advantages, the K-S1 uses a pentamirror viewfinder which offers less brightness and accuracy compared to pentaprism models. The continuous shooting speed is moderate and may not be ideal for fast-action sports photography. Battery life is average, requiring spares for extended shooting periods. The autofocus system, while competent, is not as advanced as those found in higher-end DSLRs. Video features lack some professional-level manual controls or higher resolution options. The camera’s user interface has a learning curve for users newer to DSLR systems.
