The Pentax K-1 is a camera that is great in many ways. It offers features that Canon, Nikon and Sony just don’t in a full frame DSLR while also keeping the price point fairly modest. Pentax’s strategy for years was always to take professional grade features and bring them down to the consumer and enthusiast. For the most part, the Pentax K-1 does that. With cool things like Astrotracer, WiFi, Composition adjustment, and arguably the weirdest LCD screen in the industry, the K-1 is a camera that will suit the needs of most professional photographers when paired with the right lenses.
Sure, Pentax may not have the more extended dedicated flash and lens support that Canon, Nikon and Sony do (especially in TTL monolights)–but that doesn’t mean that it still can’t be a very capable camera in the hands of an experienced photographer.
