Originally posted by Tom S. Sorry, but I would guess that 95% of camera owners (myself included) won't take any better pictures with the Nikon than they did with the K-5. If you are among the 5% elite, then congratulations. If not, you wasted your money, IMHO.
While Pentax does have almost one hundred existing marketed lens (which would include various third party ones), a somewhat limited flash selection (which unfortunately doesn't include companies such as Quantam) and also a very limited accessories selection... All of that adds up to a somewhat limited camera - especially for professional use, and even advanced use - even in hobbies.
Which is exactly why people are jumping ship left and right for cameras that have very few limitations. Such would be the base for Nikon, Canon, and runner up Sony. All three have a much better selection of cameras and items matched exactly to those cameras. So why settle for being limited by what is the existing Pentax label?
Even from a purely business aspect as well, as well as needing financial backing... Saw a very advanced professional that had all of their ducks in a line for advancing their business prospects - and then had the need to go to a bank. The bank, and unwritter - came back and saw the obvious issue with Pentax hardware. Due to exactly that (and literally only that) they did not get the loan.
Businesses are starting to see this, as are students are seeing this as well.
Pentax needs to get out there and get it's foot in the door for people such as new students; as they are the future of the camera company more so than any other aspect.
