Originally posted by zapp Many people want or request a new 2.8 70-200ish lens form Pentax. Old FA lenses are offered for much more than the price of a new Sigma lens. The message for Pentax is: we do not need such a lens in our lineup - even Sigma cannot sell it, maybe Tamron feels better here.
Pentax limited lenses probably sell well as well as the low end lenses with cameras. No more serious designs designs for years. Outch! The K3 may be the best APS-C camera overall, but the lens lineup is getting worse over time with no signal for improvements soon.
I'm just puzzled somehow. As much as I can see the benefit of diversity in the market and the more options the better it is for the consumer, but I can not understand some of the sentiments in here and in other threads. There were ideas Pentax should support Sigma with 100000$ for producing more K-mount lenses etc.
Why should Pentax/Ricoh be interested in a situation where a third part manufacturer sells more lenses, many instead of their own ones? Does someone expect Sigma would produce only lenses not available in the Pentax lineup? Also for current costumers, who do want one of the to be discontinued lenses they can just buy it now when they are available new and under full warranty. Why would they be harmed if they won't be produced in future? Why wouldn't you want Pentax/Ricoh to cover the desired focal lenghts and constructions in future? How do you think a cooparation of any sort would not incorporate a sort of agreement to not cannibalise each other (maybe like it was with Tokina, where some of the DA-identical optical constructions where built in all others but K-mount)? And, don't you think Sigma would also see the profit of bringing K-mount versions of lenses that are very popular and where they may see enough demand for them - which obviously was not the case for the discontinued one - also in future?
But how can someone claim the lens-lineup is getting worse? For the current cameras you have probably the best choice ever in Pentax history. Nonetheless, I do miss some constructions, that have been part of the lineup in the past, some TS-lenses, some super tele (not on my list), some widish and some fast primes, there is always room for improvement. But it's also cheap to demand more, and not put the money where the mouth is. Did I say it yet: I'm somehow getting more allergic to plain FUD statements (edit: not adressed to anyone personally)?
