Originally posted by Rondec I think you miss my point. I have always found aperture rings clumsy affairs that are slow to use and require me removing my camera from my eye in order to use them correctly. Some folks act as though the ultimate experience would be using an FA limited "the way it was intended," with the aperture ring. My preference is to use all lenses, where they are capable, in A mode and not mess with the aperture ring at all.
I understand completely why people want the aperture feeler for really old lenses. I'm just not sure it is high on Pentax's priority list of things to add to full frame.
It's not so much that I miss your point, but that your preference is yours and not something I need to comment on. Of course some people prefer to use controls on the camera, nothing wrong with that. And not really worth commenting on. ("You like that, but I like this, let's fight!" is rather useless.)
But the way you wrote it implies that you think using the aperture ring means not seeing the selected aperture in the finder, or at the very least others may well read your text that way. I don't want people to think that this incorrect inconvenience is how it would have to be.
So let me be super clear: "instant feedback in the viewfinder of any changes" (your words) is something I want when using the aperture ring. And at all other times too of course. And I don't want anyone to think that it wouldn't be possible.
