Yes I like them, I find the added weight a bit of a help, and the buttons for portrait orientation are great. Mind you my health condition makes using the top buttons harder. I started with a Praktica Nova, which was built like a East German tank. When I then got a new Pentax ME Super I felt it was a little small, until I then got hold of the Autowinder M II. So pretty much the opposite to Wilt. But really neither of us are right or wrong, since this is almost completely down to personal preference.
A 1 series camera would be OK, but the specification of the latest 1DXII really doesn't suite my favorite subject matter. What I really want is a 60 MP version of the 5DIV, without the maximum ISO reduction that Canon foisted on the 5DS/DSr. But of course with the grip, unless Canon want to integrate it in to a 1 series style body for me.
