And he said also that the FF prototype he's testing had no trouble with DA and DA* lenses (including the 16-50), just expected vignetting if some of these lenses (like the 16-50) aren't stopped down.
If ANY of this is true (and I am extremely skeptical) the above may be his way of indicating that the supposed full frame camera has the crop mode we are expecting and hoping for.

This is getting repetitive, who's up for some baseless lens rumors instead?

The voices in my head are in contact with with Kumao Kajiwaras ghost and he told them that there'll be a "DAX 55mm f/1.2 Limited" ...

And it will feature two aspherical lenses one of which will be made from high grade ED glass, the lens will also be apochromatic in fact: it will be the first diffraction limited 55mm SLR lens with a super speed f/1.2 aperture, delivering 600 Lpp/mm* performance at f/1.2


*this is actually the theoretical resolution limit for a perfect diffraction limited f/1.2 lens, a diffraction limited f/1.0 lens can resolve 700 Lpp/mm.

Well, who could have ANY doubts faced with such well-sourced information?


Jokes aside: Rebranding all lenses according to FF-compatibility would make sense, "DAX" for FF lenses and "DA" for APS-C lenses would fit the bill quite nicely.

To me at least the Limiteds are the heart of the pentax lens lineup and extending/updating the FA Limiteds would help to create a unique Fullframe offering.

There's probably no way around a few good FF-zooms (18-35/4, 24-70/2.8, 24-120/4, 70-200/2.8), the new DA(L) primes could be rebranded (adding a metal mount and Quickshift?) and augmented (24/2.8, 85/1.8, 135/2.8) and maybe Pentax could rebrand some usefull Tamron lenses for once (28-75/2.8 WR?).

And Pentax might want to think about closing a few potentially lucrative holes (30/1.4[APS-C only])


Here's the lineup I'd like to see one day (colors: new development, based off older design or coop with other manufacturer, existing lens):

DAX 24/2.8 - 35/2.4 - 50/1.8 - 85/1.8 - 135/2.8
DAX* 15/3.5 - 55/1.4 - 85/1.4 - 100/2.8 Macro - 135/1.8 - 200/2.8 - 300/4
DAX Limited 23/2.4 - 31/1.8 - 43/1.9 - 55/1.2 - 77/1.8

DAX 18-35/3.5-4.5 --- 28-70/4 --- 70-210/4
DAX* 14-24/4 --- 24-70/2.8 --- 24-120/4 --- 70-200/2.8

DA 18/2.8 - 30/1.4
DA Limited 15/4 - 21/3.2 - 35/2.8 - 40/2.8 - 70/2.4

DA 12-28/4 WR --- 16-80/4 WR --- 55-300/4-5.8 WR
DA* 16-50/2.8 --- 50-135/2.8 --- 60-250/4

Hmm I have to ask, why "DAX"?

Doesn't mean too much at this stage - it could just be the pseudonym for more DFA lenses in development - or they could just be DFAs given another name to distinguish them somehow from the existing DFAs.

I have full frame Pentax camera (film ) and I've tried DA* 16-50mm on it. Well, it's useless on 35mm sensor. Period.

Could it be that guy actually was actually trying out new Penatx APS-C camera with 24Mpix sensor thinking that he is trying out FF Pentax camera?

Mike Svitek claims he got to use DAX 24-120 f/4 with a Pentax FF prototype. It would be a pausible lens given the popularity of the Canon 24-105 and Nikon 24-120.

My imaginary drool on that imaginary lineup
Don't forget DAX 200/4 macro! And make that 18-35 FF zoom a first limited zoom, maybe based on FA20-35/4

A FF Pentax to rival the Fuji X-Pro1/X-E1 is all that I want.

You do realize that these Fuji have an APS-C sensor, right ?

Yes, and in many ways the K-01 + DA or FA Limiteds is already a credible competitor. But there's not a lot of competitors for a FF mirrorless - Leica I think is the only player. It's a blue ocean and Pentax already has the lenses for it.
