I am happy overall with the quality, but also frustrated about some limitation of the Pentax cameras, especially on the speedlites setup and wireless HSS.
Now, Ricoh, the latest owner of the Pentax, finnaly announced the launching of the first full frame Pentax camera (if we dissregard 645z). A first mockup, or prototype will be exposed at the fair CP+ next week in Yokohama, Japan. Let's hope, pentaxians, that is turning to a true commitment and we will see by autumn (?) a Pentax full frame on the market.
