Well, one disadvantage for sure was that the fastest shutter time was 1/500, and I guess the placement of the shutter in front of the mirror box put some restrictions on lens designs (I only owned a 50mm f/2 for it).

Yo can add Pentax Auto 110 to your list

I don't really beleaf this rumour, but I might be wrong.

Well, all my 4x5 lenses have such shutters.
I don't understand why there'd be anything hard to believe in this.
Pentax DID have a couple leaf shutters lenses, why wouldn't they have modern ones?

Which is unbelievable, considering that it is ok to redesign 645 lenses, and semi-publicly announce it, but not ok to finally introduce a pair of kit lenses for the K-mount with a decent motor? I wonder how many billions of screw drive 18-55 they have produced they can't exhaust the stock?

I don't follow this reasoning. If the 645z is designed to support both in-camera focal plane shutters and in-lens leaf shutters, then why is there a need to redesign or revamp anything? Maybe this represents just one or two new special purpose lenses.

The traditional Pentax 645 lenses will still work and be well suited for many situations, while people who want or need the characteristics of leaf shutters will have a couple of new options. That's good!

That's not good, Uluru said so. Can't you get this?

Quicksand · 09-10-2014, 03:29 PM

No yeah, you're right. Those leaf shutter guys were probably pulled off the FF project and the motorized kit lens project. Probably the electronic aperture control project too, and the free pizza for everyone project. Dang.

Kunzite · 09-10-2014, 03:42 PM

No! Not the free pizza for everyone project! Tell me it isn't true!

Quicksand · 09-10-2014, 04:19 PM

To be fair, the leaf shutter team didn't poach ALL of the free pizza team. The rest of them were pulled away by the body color combination team.

Do you think that supposedly rumoured not existing lens is a JK manufactured rebranded to Pentax.
I can feel it. So wrong, so wrong.

xD

MR himself states in the LL forum for MF that this is simply a rumor.

Chasseur d'Images tested the 645Z with 5 stars rating.
They said the most annoying things left to correct are:

Tiny AF area (right even though it is a very small con in the MF market),
lack of LS lenses which is being taken care of,
lack of tethering soft which is also taken care of.

Seems Ricoh is right on track here.
