Originally posted by interested_observer In some ways, I would prefer a Pentax natively designed wide angle lens. That said, if Pentax is going to rebadge a lens, they could certainly do a whole lot worse than the Tamron. Since Hoya showed Jun Hirakawa the door, way back when, who then joined Tamron - it would be nice to find that he might have played a part in this lens. Perhaps he was able to sneak some pixy dust in to the design. It certainly does compare VERY favorably with the Nikon 14-24/f2.8 with the reputation of being one of the very best wide angle lenses designed. Sharpness is not everything. Reviews show a very nicely balanced lens across all of its characteristics. Plus, it is also WR.
The Tamron goes for $1200, with the Nikon going for $1900 - so hopefully, Pentax will price is more in line with the Tamron.
While I certainly want Pentax to develop and market so of its own lenses, this is I ne of the cases where using an already proven high value lens makes a lot of sense.
Frankly, there are too many lenses for Canikon in some categories. Too many models means higher prices due to market fragmentation,
More is not always better. Look at Apple, Costco, Aldi's and the new General Motors.
