They aren't straight Tamron rebadges. They have a K mount, an AF PCB corresponding to the Pentax autofocus protocol, no IS motor, no IS PCB and different coatings. They are manufactured in Japan by Tamron though.

That is the definition of a rebadge to me. A bit like Vauxhall cars in the UK are Opel in Europe... Same car with a few changes, steering wheel on other side, kilometers on the speedo and a few reg changes.

Pentax lenses are designed and built by Pentax.

Weren't the Q lenses Pentax lenses?

(they were manufactured and partly designed by Nidec Copal.)

By the way, and to be pedantic, Pentax don't design nor manufacture anything. Ricoh Imaging do. 'Pentax' is merely a brand, a trademark used by Ricoh Imaging with Hoya's permission.

If it walks like a duck and it quacks like a duck, it's a duck*. It looks like Pentax, it makes products like Pentax; it is Pentax.

* Unless it's a rubber duck, and then you get "Meyer Optik" and "Yashica"

It is not clear to me that some people do not realize that if this Pentax project, and is a mechanical work of Tokina or Tamron then it is a Pentax product.

If this is the Tamron or Tokina project and placed the mechanic section of some Pentax parts, then it Tamron or Tokina product is fit for Pentax, although the writes Pentax product.

IPhone writes that the US product, which is produced entirely in China, it is an American project, not Chinese, where it is produced!

Why would someone lie to make everything clear, is the logic clear?.

I cannot figure out why it is so hard for people to understand that Pentax contracted for Tamron to assemble lenses based on Tamron designs, as modified to meet Pentax standards and with Pentax-specific (different from the OEM Tamron design) components and proprietary Ricoh / Pentax coatings. These changes go deeper that changing the pattern of bumps on the grips. They’re certainly not K-mount versions of the standard Tamron lenses in Nikon and Canon mounts. Maybe they should be labeled Hybrid.

I don't have to go with your idea of how "Pentax" is now just a label Ricoh puts on some of their products.
The people, the ideals behind the products - this is what makes Pentax what it is.

Agree, Mistrals typing fingers aren't connected to his brain.

As if the historical intellectual property in the history of Pentax hasn't trickled down into "Ricoh Imaging".

Maybe this website should be changed to ricohimagingforums.com but people will think we are photocopying enthusiasts.

Is it a full moon or something?

'Graecia capta ferum victorem cepit et artis intulit agresti Latio', you mean? May be but I'm not so sure.

Among all the people working today at Ricoh Imaging, I wonder how many were employed by Pentax Corp. in 2008.

Besides, I would experience some difficulties in trying to list the ideals behind the Pentax or Pentax-branded products of today, in particular concerning the latest D FA★ lenses: their design seems to be much closer to that of other lens makers (e.g. Leica, Panasonic and Sigma concerning 50mm f/1.4 lenses) than to the design (and 'ideals' behind it) of the FA and DA Limited lenses of yesteryear. Or to that of the Takumars.

What difference does all this make?

As long as it has a completely functional KAF4 mount and Ricoh credits "Pentax" with the revenue, then it will be good.
Everything else is talk.

Very impressive photos, Andrea.

I want to ask a question fully recognizing that it is probably a very dumb question. ... If removing the baffle on the 60-250mm effectively lets a wider usable image through to be captured by the FF sensor (and doesn't it do that?), does this effectively make the focal range closer to 40-165mm in 35mm terms?

No, it's a 60-250 in 35mm terms.

And this in the specs for a full-frame lens!

Oh dear. Someone should tell them.
