I wrote the above as a SPECULATION, and I ask you to treat it as such. Until this time noone has solid facts, so your guess is as good as mine.

Something about shutter lock, function 17, etc. Anyhow, as the creator of the KMP, please give me a bit of credit for being able to understand a bit of the "logic" behind the system. Like I said, the above thought is a speculation, but it is based on a few facts: - the *ist is designed from the ground up to be as small and light as possible, and probably as cheap as posible. I hold it for entirely possible that Pentax removed the aperturecoupling to save weight and size. - the talk about shutter lock when the aperture is not "A". enable with CF 17. Some of you say that this is for protecting beginners. From what? if the camera works fully and completely, what are they being protected from? The only "logical" thought is that with CF 17 = 0 the *ist works like MZ-60 and with CF17 = 1 it works like MZ-50. - Pentax has released quite a few bodies lately with a crippled mount - Pentax releases lenses without aperture rings (hence without that aperture coupling) together with the *ist, and calls them "perfect match". > This is what they write on The *ist D: > "Compatible lenses: K, KA, KAF, and KAF2 mount lenses" See the KMP. I have indicated that the *ist D features the Kaf2 mount. I wrote this before seeing the image of the *ist D mount where the aperture coupling is missing. I am not sure what I would have written then... > The compatibility of *ist and *ist D with K- and M lenses has been > confirmed by serveral sources including Pentax Germany. This same source that you are talking about has told me that he "could imagine" that in the future Pentax could remove the aperture rings". He/she didn't say "from all lenses", I grant you that. > The latter source also expressed the expectation that FA-J will be > limited to the cheapest price segment. The latter source could not say anthing about a new film body or DSLR a month ago. I would say that this source has simply read the press-releases himself, and repeats what he/she has read. I am not fully sure if a person in that position knows the technical operation of the mount as well as you and I do... Also, in the process of piecingtogether the KMP I have come across SO MANY wrong and inconsistent writings by Pentax (for items in production, mind you), that I will not be surprised by anything any more. > Let's go to CeBit and put an end to all this speculation! You are planning to go. Bring your favorite K-mount lens, and test things out! CeBit is already running... Cheers, Boz
