I am hesitant to enter the fray but...
Originally posted by pathdoc I'm still trying to work out if we can read anything specific into "All K mount lenses are compatible". At worst we have what we've already got (green button). At best... well, you know what us K and M fans are all hoping for.
I am cautiously optimistic that the FF will be de-crippled. Although, nothing they have officially said so far indicates either way. The reason I am optimistic is that the teasers so far do
seem to indicate an interest in attracting users with old glass, which makes sense at a point when the majority of FF glass is old. Of course, not all old FF glass exclusively uses the de-crippled mount for AE (A, FA)...
Having said that, it is hard for me to gauge whether they might de-cripple or not because I am not sure I understand why they did it in the first place. It started with low-end film bodies and spread to all bodies in the DSLR era. This seems like it started as a cost-cutting effort, but how much could be saved by omitting the aperture-coupler and related parts? Why the spread to all bodies in the DSLR era? What are the obstacles to re-adding it? How much has changed in the K-mount from the MZ-S (the last body to not be crippled, I think) to the K-3II that would make it hard to re-add? I don't see any major disadvantages to de-crippling besides engineering costs to add it back into the design of the mount. It doesn't seem likely that the
manufacturing costs of a de-crippled mount could be significantly higher. The main reason I can come-up with for not re-adding it in the DSLR era is lack of interest due to people primarily using crop lenses designed for DSLRs. Hopefully this equation will change with the FF.
End of rant.
