Photography is a hobby for me, as with probably the majority of all camera users. I've been with Pentax since my first SLR in 1981, with a few compacts of various brands in between. I am probably in for one more upgrade from my K5iis in my lifetime, and with all my lenses, it'll have to be something I can use my lenses on even if I have to use an adapter.
I can see EVF and OVF co-existing for a few years to come, but it would be nice if Pentax can bring us the option of a MILC with a dedicated adapter for use with our old lenses, and perhaps even other brand lenses.
I've been contemplating getting the K-1 for a while now, but am not getting younger, and if I make my last purchase, and still want to use it in 10 years time, it would be good if it is actually smaller. I can see the positive in seeing real time exposure changes through EVF, but what I find most impressive in reports on the A9, is the focus....(tracking and all the points all over the sensor). As I get older, I want life, and my hobby to get easier, not more of a chore.
I've never tried EVF before, and am not an expert in anything "computer stuff", but have always been a "gadget man", and seeing how fast technology have come in a relatively short time, and the acceptance and use of it by a new generation, it might be possible that MILC's sales and use, will eventually surpass OVF cameras.
"Propaganda"...perhaps... (business is business), but how do the major players react to it, are they countering it with propaganda for DSLR's or are they starting to follow the MILC trend? I also think mainly new entrants into the market will probably be influenced by it (IMO), your basic DSLR user would probably only change for realistic and practical reasons.
Who knows Ricoh's plans for Pentax, but if they are satisfied with a high margin, reactionary (slow to adapt to change) path to demand, they will stay a small player, who might ensure Pentax future with a good quality product at reasonable prices and a dedicated, but probably aging and eventually declining, user base.
If I can't physically handle my DSLR anymore, and Pentax do not have an alternative, where I can use my lenses, I might be tempted to look around at other brands that caters for my needs, even if the bodies are more expensive. If I can use all my Pentax glass on such a body I might be tempted to jump ship. I love my Pentax gear, but I also try to be realistic in my approach to life. As I get older, I realize more and more that time is not to be wasted, and if I can save time doing anything and getting acceptable results the same time, why not?
I think Sony is at the forefront of change in the industry, which will probably gather steam sooner than expected, whether we like it or not. Camera manufacturers that do not adapt to changes and demands of a new generation, will probably die, or stay a small fish in the pond, like Pentax probably will do.
For those with physical problems using EVF, and as I haven't used it before, might even be one myself, don't despair, life will go on and as long as you are prepared to pay, someone will keep making OVF products
