It has been an interesting read so far. Just waiting for the rest of the story to be played out - one way or another.
The bottom line is, that light goes through the lens, is focused on the sensor, the photographer composes and captures the image. Personally I like optical mechanical lenses. I like my screw drive, and on a tripod - manual focusing is ok.
I stayed with Pentax for two reasons - the in body stabilization and the Pentax glass from yesteryear.
I realize that something will need to happen, and for Pentax as a brand (notice, I did not say company) - it needs to accommodate the current K mount. I don't need SDM (they fail / break / really don't revert to screw drive (well ok, the "work a round"). I do have "one" the Sigma 8-16. I have gone so far as to remount some old Contax Zeiss manual glass.
The comment on Ricoh / Pentax / Acme is - I think more true than what may have been intended.
The bottom line is - what ever the future holds, it needs to be drop dead SIMPLE and dependable, works the first time, every time and all the time. I do not want to be plugging 42 lego parts together to take a f**king image. If I am becoming to sound like an old geezer - well I guess it will happen to all of us, given that we live long enough.
I would like to see some of the classic lenses - updated. It appears that in form of the K mount that may not occur - which is a shame. I really do not want or need electro-wizardry in an optical lens. Not against electronics at all - I make my living in computers. That said, I am out capturing images, and I don't need the SDM - whatever lens becoming a disposable consumer product. We already have that with the bodies. There is no way, I am going to put $500 to $2000 into a disposable consumer optical lens and have it go sour, then have the vendor walk away mumbling "too bad - so sad".
