Originally posted by Kelvin 5500 Typical U.S street price is only 10% more for the Pentax branded lens with VC image stabilization absent, although not needed. Also, Tamron branded lenses
sold in the U.S. include a 6 year warranty versus the Pentax 1 year warranty. The weather sealing seems to be identical on both products. There is, of course, no available alternative for an auto focus 15-30mm F2.8 full frame lens with Pentax mount compatibility.

For what it's worth, the Tamron 15-30 uses Tamron coating, while the Pentax version uses Pentax's HD coating -- a significant upgrade over anything Tamron has available. (see Ricoh's website)

Regardless, the Tamron 15-30 for Nikon is 1300 and the Pentax 15-30 is 1200 (B and H pricing). This was mentioned earlier in this thread, but clearly you missed it. Therefore the US street price shows the Pentax version (with better coatings) to be ten percent less than the Tamron version.
I do wish that third party lens makers released more of their new lenses in K mount. Particularly some of the telephoto options from Tamron and Sigma would be nice for Pentaxians to look at. At the same time, Pentax gear is actually very reasonably priced. Pentax isn't doing the fire sale thing with their gear any more, but it certainly isn't more expensive than comparable lenses from other makers. Particularly not if you start looking at prices of new lenses for mirrorless full frame offerings from Canon and Nikon.

Originally posted by normhead What's affordable for one isn't affordable for others. Pentax no longer desires to be the "affordable" brand. When I look at flickr, and I see there are more Pentax shooters than Rebel Ti6 shooters, I wonder, why would you waste resources on entry level cameras in this market if you can sell more high end cameras?
As I noted when the K-1 came out. Pentax is focussed on quality, not the kind of rock bottom lenses that are "affordable". They aren't going to put a lot of effort into "bottom of the barrel" low margin product. I bought my FA-J 18-35 new in box, years after production ended. Cheap and dirty didn't sell.
After all these years, I've sent back more Sigma lenses than I've kept and as many failed as I have. Maybe they area good idea for light users who mostly want lens to keep in the closet for the odd time they need it. I haven't found them to be every day lenses, and 1/3 of the ones I've purchased have been so substandard new right out of the box I sent them back.
Of my 6 Sigma purchases 4 are now trash, or were trash as delivered. I've never had to return a single Pentax lens.
I think I would just say that Pentax no longer makes many "cheaply made" lenses. Even the 18-55 kit lens on my daughter's KS-1 feels pretty sturdy and not as though it is going to fall apart if you look at it the wrong way. At the same time, I don't feel as though Pentax is going Leica on us and releasing lenses that no one can think about owning because they are so expensive. Sure, the DFA *50 was really expensive, but later this year they are releasing a 70-200 f4 that should be more reasonable. They should come out with a 70-300 variable aperture zoom for full frame too, that should be more reasonable as well. While the KP is 800 dollars, it isn't the cheapest Pentax and the K70 is just a hair under 600 dollars and offers weather sealing, penta prism viewfinder, and dual control wheels for that price. The T6i has better video, but it isn't sealed and has a pentamirror viewfinder.
Anyway, I know you aren't disparaging Pentax. I just think Pentax decided to forego the K500/KS-1 range -- what used to be the under 500 dollar SLR and start at the 600 dollar point. I think the reality was that they didn't sell many low end cameras and they probably ended up losing money on them in order to get them out of inventory.
