Anyone Else Worried About Lack of Pentax Version of New Tamron Lenses?
Nope. If you are going to use Tamron or Sigma lenses, why bother shooting Pentax at all? There are much better cameras out there that will mount third party glass.

Maybe because at the price points at which Pentax is currently competing, there aren't better cameras out there that will mount 3rd party glass?

Maybe because someone wants to shoot Limited primes AND have access to 3rd party zooms that fill a niche Pentax doesn't?

Maybe because some people prefer AND to OR?

I'm not worried. I can build a perfect kit for my needs with what Pentax offers.

But extra choice is always nice.

So if I drop my Helios 40 I'll end up with a bent lens and a bonus crushed chihuahua?

I'll consider the build quality of the ~220 lenses I now have. [/me considers]

OK, some have metal (usually brass) bodies, some plastic, some are hybrids.
Not all plastics are created equal. Polycarbonates (Lexan) ain't polystyrene.
Not all metals are created equal. Brass isn't steel. Brass bends more easily.
Drop a brass-body lens from 1m. Oops. Drop a plastic lens. Hay, it bounces!

Much so-called "build quality" appeals to our sense of touch. Brass feels good!
How a lens feels when fondled, doesn't correlate with how it survives impact.
If it feels good, use it! But carefully. Don't drop it. Don't crush any chihuahuas.

Not now that Ricoh has demonstrated their commitment to the K-mount so enthusiastically!

The Tamron 70-200 is an awesome lens. Lighter than both the Sigma 70-200 and the Pentax 60-250. Full frame. Focuses great with the K-5 screwmotor. Good for macro. Cheap. Faster than the Pentax. This comment won't be popular, but when I compared the IQ to the Pentax it was a toss-up, with one test showing the Tamron better and one showing the Pentax better.

I like both the Tamron 70-200 and the 15mm limited. I like the 55-300 and the 35mm macro. I like the Sigma 500mm f/4.5.

On pentax there's a nice mix of Pentax and third-party lenses.

On top of that, for it's size, there's not a better camera around than the k-5.

I would like a full-frame, fast aperture general use zoom. like the DA 16-50 2.8, but in FF (i live in hope that Pentax will eventually build a FF body ). at the moment, that doesn't seem to be an option for pentax. Tamron and sigma seem to be our main hope atm.

Pentax is in a peculiar position. Pentax dSLRs are the price-performance leaders. But Pentax lenses usually cost rather more than 3rd-party equivalents, if still rather less than Canikony counterparts. (Except cheap novice lenses.) The predicament: How to make Pentax-quality lenses to sell at Tamron prices?

Something smells off.

I have had Pentax cameras for over 20 years and the third party lense companies always had offering for the Pentax K-mount (Sigma, Tamron, Tokina, Cosina etc) but these number have fallen. I really hope that Tamron hasn't left the fold but agree I haven't seen a new K-mount lense from them for a while.

We neeed competion in the field. If Pentax and Sigma are left as the only suppliers then price, quality and capability improvements could start to fail.

Don't forget Samyang. But I suspect that as Pentax starts overtaking Canon in camera sales, more Pentax-mount lenses will appear out of the woodwork. The days of Hoya screwing-over lensmakers (and sellers) are past.

I've said it before but I think it needs repeating: Hoya ran off Pentax partners. The turn around will take a wee bit of time as Ricoh works to rebuild bridges that the accountants at Hoya burned.
