Fresh from the Pentax Ricoh launch event in New York, we've put together a real-world samples gallery from the Pentax K-50. The 16MP mid-range DSLR builds on the very likeable K-30 and promises improved image processing. We take a closer look at the K-50 and its similar sibling, the K-500, to see just what they bring to the table, as well as presenting a selection of full-resolution sample images.
