New telephoto lens design patent

I guess the lack of telephotos has become apparent to them.
All with SR, meaning, there must be a camera coming with combination IBIS and SR integration? Maybe? Or more likely you just turn SR off like I did with my Sigma 120-400.

There is only one.
Such patents have several "numerical examples" - but we might see only one of them made into a real product.

OTOH, I agree, this means in-lens and in-body SR. Pentax has both, but so far never combined.

I would think a lens that makes it to 600/5.6 would be Star glass and who knows what size it will be...

And what will it cost? $10,000? Which means they'll sell tens, or even dozens a year.

Like the Sigma 150-600 C or Tamron 150-600 SP?

Yes

But if they want that range, they can do a Tamron rebadge. The G2 version should be good offering.

No, but the Oly patent may just be it.

If they develop it themselves people will just call it Tamron rebadge anyway. Why would they bother?

Of course, but is not any Pentax body a rebadged Sony? With a few tweaks to give us those brilliant jpeg's? And a body shaped like lovers of the Pentax brand expect?

I'd call it max aperture opening diameter instead of front diameter.

No, they're old Konica-Minolta DSLRs which Sony found in some warehouse and decided to recycle.
The K-3iii itself is a Konica-Minolta 7D, which explains its slightly higher performance compared to any other "Pentax" camera. What we call an "accelerator" is actually software interpolating the image from 6 to 26MP.

I am surprised and offended, someone could understand this as a great truth

, as a real truth that you will not be able to deny because someone will not want to believe, my first DSLR was Pentax Km 12 years ago and since then I have only used Pentax (Km / x / r / 30/3/1) not counting the shift 8 I inherited from my dad, I entered the world of DSLRs with Pentax Km 12 years ago and I could believe everything, when I bought my first DSLR I asked for advice from acquaintances, recommended I like Pentax because he took pictures with Pentax K1000 a long time ago / he still has it, and another friend mentioned to me that he used Minolta but that it is better to stick to Pentax, I took both of them seriously (an acquaintance who once took photos with Minolta now distributes Konica-Minolta photocopiers)

Glad to see Ricoh aren't even trying to challenge Canon RF long lenses with an entry level 1200mm f16 lens

So barely covers 24x36mm FF?

sqr (24² + 36²) = 43.27

21.64 x 2 = 43.28

These lenses are optimised for a 24x36 sensor, not 'barely cover' it.

I will take your word for it. 43.28 - 43.27 = 0.01mm

(...did the math before I posted...)

The same figure, 21.63mm or 21.64mm, can be found in any and all patent applications corresponding to 24x36 lenses.
