I am a professional photographer [...] and usually shoots with a Pentax Ricoh 645 D. Following a loan Pentax, I adopted the K3 not only as "back-up" but I also use it for images that require discretion, speed of execution in difficult light and casual shots ... Accessibility to pro settings is a real treat, not to mention stabilized housing ... For now I use it with a 21 and 70mm, once micro adjustments made, we just work at full opening carefree :)))
