Originally posted by Rondec I think Pentax has decided to release things when they are done. As such, they don't really signal all of the things they are working on. If they released an updated DA *50-135 in the next six to nine months, I wouldn't be surprised at all, but they haven't said that such a lens is coming.
They haven't said the DA* 16-50 PLM was coming.
It makes sense: on the roadmap, they'd put the new lenses which don't directly replace existing ones. They know these would stay quite a bit on the roadmap.
But how would it be, "hey, you might want to stop buying that D FA 100mm WR you're eyeing right now, because we will have a replacement - 2022 or later"?
They simply don't want to tell us, years in advance, that they'd replace a certain lens.
