Thom Hogan is a Nikon user manual writer, who is also known as a blogger that writes about cameras and the photography industry. He's often engaged in various photography forums, writing endlessly long comments and opinions. In one of his latest blog posts titled The DSLR Cash Cow is Alive For How Long? he laments the iterative updates by Canon and Nikon in the shape of their recent D780 and 1DX Mark III releases. In one of his initial paragraphs he says following:
What I'm seeing is the traditional Milk the Cow approach to the DSLR to mirrorless transition, and not an overly well done version of that, too. All the accountants in charge at Canon and Nikon appear to think that there's still "some money" left in the DSLR till they can extract, but they don't want to spend too much in money or effort to get it out.
