Quote: I'm a bit peeved that in 2014 people still complain [...]
The wish for an uncrippled mount was expressed since the introduction of the *istD. It was also communicated to Pentax Japan (via e.g. Pentax Europe/Germany) several times - but ignored. In the CP+ interview 2013, Ricoh told us that the "transfer and pray" policy now is over. Feedback from enthusiast users will not be ignored anymore. Also the question was posed: Will "the Pentax K-mount ever be de-crippled". The answer was yes, if such user feelings would be expressed. There are users (me included), who would buy a(nother) DSLR just because of this single feature. I want to use the aperture ring of my K, M, A, A*, FA, FA* lenses. In macrophotography and using flash, the current severe restrictions are a nuisance. Full functionality should be allowed - if not in all, then at least in certain models. Some users paid a 250€ premium for the K5IIs over the K5II for probable minor improvements in image quality. Why should owners of high quality and expensive "old" glass not pay for better handling and functionality? The cost for parts for the manufacturer is very probably below 1$. Even if the majority is not willing to pay say additional 10$ for a >1000$ product, an alternative could be offered, e.g. a K-3 d(ecrippled).
How fast does the number of 25 million Pentax lenses decrease? If you add K lenses from other producers, then Pentax even claimed in 2007 that the "PENTAX K bayonet is the world's most widely used lens mount today". Are lenses without an aperture ring not the clear minority? What Pentax tells us:

With unmatched lens backward compatibility, the creative options are endless.
Originally posted by http://support.us.ricoh-imaging.com/node/14 (K20D): Full backward lens compatibility
PENTAX has manufactured over 25 million lenses in the last six decades; all DSLR bodies offer backward compatibility with every one.* Whichever lens is used, whether the most recent lenses or a classic screwmount, it will faithfully capture the image desired. *With adapter for screwmount and 645/67 lenses.
The advertising is a bit in contrast to the answer at CP+ 2014, isn't it? The compatibility argument was valid before and after the Hoya regime. But "unmatched" and "full" compatibility is still not guaranteed in 2014.
PS:
The aperture coupler was first killed in the entry-body MZ-50/ZX-50. The low-budget FAJ (sometimes taunted as J-unk) lenses did no longer feature an aperture ring. So, this trend really started at the lower quality end. Not many users did complain, as the better models did not suffer from these restrictions.
Originally posted by http://kmp.bdimitrov.de/technology/K-mount/crippled_AF.html: The only reason for the existence of this mount variation is cost cutting. This was achieved by leaving out the stop-down coupler of the body mount and the aperture ring of the lens mount. With this move Pentax sacrificed one of its strongest advantages, the unrivaled K-mount compatibility.
Unfortunately, both restrictions now apply to all DSLRs and nearly all lenses. However, there is another reason for the missing aperture ring in WR lenses. According to hearsay, it already was contemplated to add weathersealing to the FA* lenses. This was cancelled due to e.g. problems of sealing the aperture ring. I would have preferred an aperture ring over WR, however.
PPS:
Quote: I think Pentax would need to offer one cheap 50 mm lens, similar in principle to the current DA 50 f/1.8, but in FF
The DA 50/1.8 is a variation of the FA 50/1.7:
DA 50/1.8
The DA 35/2.4 is even closer to the FA 35/2:
DA 35/2.4
The DA 200/2.8 is a new edition of the FA 200/2.8.
Etc.
The denomination DA does not exclude FF compatibility.
