16-50 f 2.8 adnd 50-135 f 2.8 are co-developed with Pentax, but differ in optical design, for ex. in no. of AS/EX/SD lenses.
Also, the coating are not smc on Tokina variants.
Iven Samsung S.K. 12-24 f4 whitch was made by Pentax, show no smc - more prone to flare.

DFA100 and FA100 macro are Tokina optical design.

It would be interesting to put the d7000 and K5 head to head using Pentax and Tokina equivalent lenses, do you know if anyone has tried this?
Is SMC that much better than Tokina coatings?

Tokina designed the 12-24. All of the other joint Tokina/Pentax lenses were designed by Pentax. A few years ago someone posted here links to the patents for these lenses, which are held by Pentax.
Tokina also designed the 11-16, which so far Pentax has not adopted. It is based on the 12-24. Tokina also designed the old 80-400, which may still be available in other mounts.

I have the Tokina 12-24 DXII and it's a great lens. Minimal flare, no discernible PF. While I haven't tried the Pentax version, the photographs I've seen from it are no better than those which I produce with my Nikon. My belief is that when Pentax came out with their SMC, it was innovative and advanced but other manufacturers have pretty much caught up now. In fact I suspect the superiority of SMC over other modern lens coatings is one of those cherished but groundless Pentax myths.

Huh? Show me the difference.
SMC is just a brand name now. This has been discussed, and it looks like the Tokina and Pentax coatings are in fact the same.
Tokina lenses actually designed by Tokina at this point are the 11-16/2.8, the 12-24/4, the 16-28/2.8 full frame, the 16.5-135, and the 80-400. Of those only the 12-24 has a Pentax version.
Those designed by Pentax are the 16-50/2.8, the 50-135/2.8, the 35/2.8 Macro, the 100/2.8 Macro, and the 10-17 Fisheye.
.......Hey wait a minute, Tokina's website no longer lists the 50-135. Which is funny as it's by all accounts a far better lens than the 16-50.

So the question would be, does a Nikon with Pentax designed glass still produce images that look Nikon or iare the images more Pentax in rendering?

Well there is some evidence by inference. For one thing all the Pentax 100/2.8 macros shares the same 9 element 8 group design with a fixed rear element. So does the older Tokina AT-X 100/2.8. One of the key things about Tokina is if they make a design for someone else they retain the right to sell the design to other camera brands if they wish (except in the case of the long pro Nikkor lenses they build for Nikon as they are not allowed to compete with those designs). Same as when they collaborate. When they make something for someone else they may have to stop selling their own lens with the same mount. In the case of the Tokina 100/2.8 Macro the lens was available orginially in Pentax KAF mount, which means it predates any relationship they have had with Pentax. So it is possible the Pentax F 100/2.8 Macro brought out in 1987 was a Tokina design. The Pentax 100/3.5 Macro was definitely a Tokina design which they built or sold to just about anybody who needed a macro lens design (Pentax, Cosina, Samyang, and just about every small lens remarketeer). Tokina does not buy macro designs as their original 90/2.5 Macro (which may have been a Vivitar ODT design like most Series 1 designs) was rated by Photodo as one of the 10 best lenses of all time (film days)(4.6 rating).
But I have never heard of any denials from Pentax or Tokina on this about the 100/2.8 designs.

Actually Pentax owns the patent for the 16.5-135 lens produced by Tokina, its such a bad lens though that Pentax doesn't want their name associated with it LOL

I have a couple of the Tokina lenses for my 7D. Both the 12-24mm and the 50-135 mm are comparative bargains, purchased for about 50% less than what the Pentax-branded ones go for on the used market.
As noted above, no differences in rendering from the SMC versions which I owned for years. The 50-135mm has a tripod mount which is very useful. The Tokinas also are built more bullet proof.
These lenses are available for a lower price because Canon zooms command much of the market. The 11-16mm seems like the first Tokina that has earned significant mindshare. That 16-50mm f2.8 has a lousy rep, which I felt also applied to the Pentax version.
Re: SMC rendering on native Canon bodies, I have two adapters for EOS to K-mount and M42. The rendering is not any different from either fine Canon glass--in other words it's a Canon rendering and a good one at that.
Size and weight are the major differentiators from Canon glass.

The newly rolled out Tokina 17-35/4 was said to be co-designed by Pentax.
It's a FullFrame (FX) lens.
There was some discussion about it on the Nikon board.

And the Tokina variants dont have SDM, so they also work correctly.

Believe what you want, but I can do stuff with my Pentax glass that friends using Nikon and Canon cannot do under the same conditions because they get lens flare. The other manufacturers have certainly gotten better (and Lord knows they had to), but so far, I don't think they are quite there yet.
I've heard some good things about Nikon's new nono coatings, it might be as good as SMC.
