Ok, not going to bother trying to read that small pri...pixel!

Here are larger versions:

3 new D-Fa lenses for K-Mount:

~15-30mm f/2.8(?)

24-70mm f/2.8

28-105mm f/??

 

also 2 interesting zooms for 645:

45-85mm f/4.5(?) 

~95-190mm f/4.5(?)

Typically on the Pentax road maps, the range of the future lens is a bit past the end of the fade-out on those bars, so:

 

DA 10~30  From the range, I would guess this would be slow zoom (f/4~f/5.6) Or possibly a replacement for the DA 12-24/4

D FA 24-70.  Large diameter zoom, so yes probably f/2.8

D FA 28-135.   Probably the kit lens for the FF body, so f/4~5.6...

D FA 14~30.  Large diameter zoom, so probably f/2.8

 

The first 645 lens is probably a straight up DA replacement for the current FA 45-85mm, adding HD, AW and SR.

The other lens is probably a companion DA zoom with the same features.

I wonder now if some these will be re-branded Tamron lenses, like the current 18-270 lens.  Might make more sense for the low volume of this system.

None, why people are trying to spread that kind of rumors? Do you think Pentax are unable to design and produce a lens? The most likely, but not that probable given the lack of news, would be a Tokina collaboration.

Indeed, Tamron has a link to Sony. Would be odd to see Tamron lenses badged as Pentax, especially lenses which Tamron does not have itself?

If the Tokina connection hadn't died, I would've sworn the "D-FA large diameter (WTF???) wide zoom" is a rebadge of their 16-28. But it's most likely not. THAT is something that Pentax has done in the past, and I don't think it's something they should've been ashamed off. Cooperation is never a bad thing.

Like I said, the current Pentax 18-270 <i>is </i>a re-badged Tamron 18-270, like the Pentax 18-250 was before it.

Sony has a links to everyone, so?

 

Tamron has both 15-30 and 24-70 lenses...so it's not impossible.

Which people?

 

It's not a question of ability but resources (time, cost).
