You might just be right.
He is lowlife in the Pentax world in my opinion, and really damages the community sprit here and on the other forum.

If memory serves me correctly, Pentax has also partnered with Tampon for their optics previously as well. Though, I'm not sure if it was just con-licencing or actually con-operation.
Well, as long as the product has good absorption...

Tampon Tamron, what's the difference?

I'm not sure how I feel about this.
I don't know personally, it seems that Tamron is possible a few years behind Sigma when it comes to the quality of it's products (at least in K-Mount), but they seem to have the drive to compete and their recent lens releases definitely confirm that they're ready to go into a full nuclear war with Sigma, which is fantastic, as brand-name manufactures seem to have lost both the drive and their creative intuitive to push optical design.

Sometimes autocorrect can be a curse.

after seeing these three lenses, I guess there is no doubt PENTAX is not doing a FF camera.

sigh...

When Ricoh finally releases the FF, we'll probably change our minds.

Does anyone have the link for the 70/80-200mm f2.8 patent that Ricoh filed recently?

I think this is a patent filed by Ricoh and its optic formula

There is also some discussion about it on photo rumors: Pentax patent for a 70-200mm f/2.8 lens | Photo Rumors

(...)
Several of the embodiments in this patent show a 15-45mm f/2.8, the image circle of which is that of a 1/1.7" sensor.

This patent, also showing embodiments corresponding to 70-200mm f/2.8 24x36 lenses, is that of Pentax-06 Telephoto Zoom 15-45 mm f/2.8, a Q/Q7 lens.

It is also how Sigma designs its lenses. Maybe the long tele zoom is just a rebadged Sigma. Or the people who designed it came from Sigma. Maybe that is why Sigma isn't releasing many Pentax lenses. The K-mount people went to work for Ricoh...
The focus ring for the DA 18-135 is also at the rear but I don't think anyone has suggested that it's a Sigma design.

I'm pretty sure they're not developing a Q system lens that is over 20cm long (in physical length). Would make for a cool lens though.

and on a blog which I will not name here because we don't like him but he says "Besides, this new lens should include an in-lens IS (or SR in Pentax' terminology), as the image circle just fits and there is no spare space for the body SR anymore."
The hell with Internet self-proclaimed experts!

Asahiflex had a 37mm screw mount and, nevertheless, they were 24x36 cameras.

Ans how do you think Sony are doing with their A mount lenses, including all heritage lenses, and 24x36 stabilized sensor (Alpha 850, 900 and 99)?

Just be clear Mistral. What are you saying? This is not a 70-200? Or it is not full frame or there will never be a full frame?

Pentax + Tamron = Tampax Tampon?

Well the 16-85 is good news as its a Pentax lens and not a rebadged Tamron, so Ricoh will have more funds to plan new models in the future, now the first of the other lens is a rebadged Tokina 70 200 f4 the size is exactly right, its large enough to be full frame but not large enough to be f2.8, the switches are in the same position, and I think are focus limit on/off and focus on/off, this is the same as the 560mm lens, now the second lens probaly a version of tokina's 80-400 about the same size, the forward button is zoom lock (same place on the old Tokina), now the other buttons hum! one is focus on/of the other well if we think back (not you digital guys - before your time) yep a slider switch and a button POWER ZOOM yes Sony has just resurrected it in a new standard zoom so !!!!, well the button could be favourite focal length and the switch a memory set switch, oh well time will tell, but I bet both are full frame.
