Some people cite as the reason they buy Pentax is because the Pentax line is generally cheaper.
Could be, but not in my case. When I tally up the thousands of dollars I've spent on Pentax gear since 2007, it is considerable.
For what I've spent since '07, I could of bought a Nikon FF camera with Nikkor ( do they still call it that, or is it just Nikon) 70-200 F 2.8, 14-24 F 2.8 lens, Sigma 150-500, 105 Macro, 900 flash gun, etc.
But I like Pentax equipment, it works well for me, so far I have no complaints. So why change ?
