I wonder if they should just ditch the idea of SDM altogether and ask Sigma to build Pentax lenses with HSM or something. This will considerable reduce time to market of a revised "DA* 16-50 II" and introduce other new lenses like the 18-35, 70-200, under pentax brand... and most likely with weather sealing.
Smart companies do this every time... There is nothing wrong in recognizing that someone else's tech is better than yours. Just look at Apple with Siri (adquired from SRI), Microsoft with their Kinect (adquired from a company called Primesense) and the list would go ON and ON and ON....... I don't own a SDM lens, but the more I read the less I want one. Just the fact that they're so famous for its low quality motor, I wouldn't throw $1k in a lens I know most likely die tomorrow. You can argue that you own 1 SDM for 3 years with no problem... but unfortunately, the bad quality fame of the SDM is just too big. And until they fix that fame (even changing the name to something like SDM2 would help) pentax lineup will not be complete as SDM is not even an option.
Just imagine if Pentax would take something as simple as Sigma's 17-70 C and add weather sealing to it and make something like "Pentax DA 17-70 2.8-4 HSM Macro WR". Yes it would mean that they will eat up lenses they have like the 16-45 F4 but to be honest is better to kill your own product than to have someone else kill it for you. Or do you think that Pentax did not know that coming with K-3 was going to kill K-5II sales? Yes of course they know it, but is better to kill
YOUR K-5II sales with
YOUR K-3 rather than Nikon kill
YOUR K-5II sales with
THEIR D7100 or D7200. So is better to have Sigma make your lenses (at least the 16-50 2.8 or something in that range) put Pentax on them, Kill the 16-45, and most likely the 16-50... Rather than be offering laughable product and have other companies kill your product.
I know pentax has done this in the past with Tamrom lenses. Why no do it know when SDM is clearly NOT working 100% yet?
What lens is there that will truly match the K-3 in 16-70 range? I wouldn't really buy a 16-50 2.8 when I know (from reading
This REVIEW ) that the pentax one costs 2X its rivals and is the worst of the batch!
Anyway, you can argue that pentax has the most comprehensive apsc lens offering, but in reality, nobody needs ALL the lenses... who cares if there are 1,000 different lenses when you cannot really find one(1) that is as good as a 17-70 Contemporary from sigma w/o having SDM problems? yes you cannot compare the 16-50 with sigmas 17-70.. but precisely!!!! how would I buy the 16-50 (2x the cost of the sigma) when i know it has laughable SDM which can die within a day of use?
