This is beyond reasonablilty. Of course not every single lens made and SOLD - these werent freebies - is no longer in existance or in perfect working order. Nobody claimed that but as I stated in my previous post these were extremely well made lenses and are generally both durable and reliable even to this day. No one knows the exact number but I would bet (based on my long experience with them) that the vast majority of them are still fully serviceable INCLUDING the aperture cams essential to open aperture metering and AE that Pentax isnt currently supporting....Quality lenses tend to last for decades..thats why its important for any company to support them if nothing incompatible is needed or developed and nothing incompatible has been developed, they are still compatiable with the latest mount, just not supported for features as designed.
The lack of reason is in your last post, there is no imcompatability issue with KM lenses and Program AE and AF. they didnt have to remove KM support to maintain Program AE and AF. If they did then it might make sense but they didnt. And BTW, I think the statement is quite illogical because on one hand your saying program AE is important for most users but then you ALSO say the removal of ALL AE from KM lenses without the need to do so is right thing to do. YOU CANT ARGUE AE is and isnt important at the same time. this is getting old because you made the same self-incriminating argument before a while back and never learned from it when I pointed out its gross contradiction then. I told you that you would be a redundant arguer didnt I?

I read Pål's numbers after that reply. The manufacturing numbers do not take into account equipment that is no longer in service for a variety of reasons, such as equipment loss/destruction, things that happen OVER TIME. Anyway, the manufacturing numbers are, at best, a straw man, and at worst just not valid at all in this curcumstance. The most important factor is lens usability for THE MAJORITY of users. For most users, this means programmed exposure automation and autofocus, neither of which are supported, or supportable, by K/M lenses. William Robb
