Originally posted by Marc Sabatella It's one thing to say a handful of people on a forum buy these lenses, another to say they would actually sell in sufficently qunatities to justify the amount of money it would take to develop such - especially since simple economics siggest Penax could never sell theirs as cheaply as Sigma or Tamron.
As for FF course, there are a millipn existong threads debatng that topic, but the bottom line is the same - it would cost a huge amount of money to develop such a system, and Pentax apparently deems it unlikely it would sell well enou to be worthwhile.
Well canikon don't sell theirs for the same price as tamron and Sigma but they still sell in big numbers I believe
A lot of people would prefer a Pentax lens.
And the Sigma now that it comes as an OS model only actually may end up more expensive than a comparable Pentax (in the 70-200)
The other thing is I would expect the Pentax variants to come out as high level WR versions (IE a FF version of a DA*) which would justify some cost
If they do in fact move into the FF arena they will pretty much have to release at minimum a 24-70 2.8 and a 70-200 2.8 (and probably a wide 12-24 as well though f4 may be enough there) I would think any FF Pentax client would also expect them all to be WR construction
I think it's more accurate to say Pentax (Hoya) didn't believe it was worthwhile. At this point in time we have no idea what Pentax Ricoh thinks since there have been no announcements or roadmaps
