Originally posted by mikeodial Not to rain on the parade that I was also waiting for, but I think the lack of modern lenses will be a key factor in getting others to move to the brand. Most of the best lenses are two generations old, and while good, they can't compete with the newer generations from Zeiss and others; there is simply not the range to chose from. So Pentax will have to either convince others (Sigma is the only other real platform support right now) to create lenses that support the new FF. I am sure the sensor will be great, and the camera function will be also, but that alone will not cause others to move over to Pentax FF.
My informed bet is - over the next 18 months - the primary focal lengths in both prime and zoom lenses will be released (or re-released) with all the most modern features, Tamron will re-enter the game, SIgma will grudgingly offer some lenses on K-mount and something unexpected will happen.
There will follow a year of consolidation of gains, some APSc noise, perhaps some action on Q, some 645 lenses - and then (if all goes well with the new FF) some line expansion.
We need to look forward. Ricoh Pentax is not a static company.
