If continous open aperture AE is so unimportant why did the top line model pentax offered from about 1973 on have it? Secondly I know the differece between true AE and what the ist D is offers. If you have to press a button every time you want a new automatic exposure that is really just a modified metered manual because it takes human intervention to keep updating the reading, true AE is continously updated fully automatically.

Although I can understand quite well your concern for planned obsolescence, let's look at it more pragmatically - when ever do you need to change exposure so quickly that you need AE with manual focus lens? You can just as quickly press the green button every few seconds. And if you think that's inconvenient, just ask some photojournalists - HyM mode would be my most used one, if my current cameras had it (different brand <g>). Good light! fra
