You do realize, don't you, that air comes in and out any lens without floating element focusing, e.g. nearly all of the Pentax limited primes?

Ironically, weather sealing on zooms is pretty useless as air must come in and out. Weather sealing on primes makes much more sense, but not all Pentax primes are weather sealed.

He he... yes, I wrote a post and then also realized that even primes that are not having internal focusing breath in and out.

When I bought the DFA150-450, I questioned myself about durability of the zoom over time compared to the DA300 prime or a longer lens such as DA560 or Sigma 500. The DA300 prime has internal focusing, so I believe weather sealing may be more effective against dust. I think with zooms from Tamron with several years of use, some of them ended up having a few dust inside the lens that can't be cleaned without opening the lens.

Yes, moisture comes in and out, but the point with WR and AW are that it´s watertight.

Pentax could have done in the end of the cooperation with Samsung as they did at ~1975 then they came out with K mount. They could have let K mount be free. In the seventies Vivitar, Ricoh and many more brands use K mount, but later on Ricoh made a different k mount that was not compatible with Pentax.
And that was a problem.
Today Pentax can let K mount be free again, but with a contract so for example Fuji, Casio, Sigma and Yasica can make their own cameras and a few or more lenses with K mount. That can be very good for both K mount and Pentax.

Huh, you mean Pentax decided NOT to open KA-mount.
Others did not have much of a choice did they ?

K-mount is free, it has always been.
KA-mount patents expired AFAICT so it is factualy free.
KAF, KAF2, KAF3 are still covered by patents and not free to use (till now at least).

Actually, it's Hasselblad that will be the first camera maker to announce a mirrorless medium format camera: on June 22nd at 2pm CEST.

Same 50 Mpix CMOS sensor as Pentax 645Z (and Hasselblad H5D-50C, H6D-50C and CFV-50C).

But do they have lenses? The Hasselblad mount flange distance is even longer than the 645-mount

I presume:

- this new camera will have a new mount with a relatively short flange distance
- they will do the same as Leica for the SL launch: a couple of dedicated lenses and adapters for H and V lenses.

But I might be wrong and they could reuse their H mount, as Sigma did for their SD Quattro.



By the way, Hasselblad are teasing a second part of the puzzle camera on Instagram and Facebook today.

Indeed. This corresponds to what I was calling "a relatively short flange distance" compared to a 69mm image circle diameter.

Go figure Sony RX1 or Leica Q in 35mm.

Looks like they are trying to play the game Pentax invented with the 645Z? affordable MF perhaps?
