I think the most significant thing is the significant price drop for MFD (I think maybe it still has a crop sensor though?).

If this one's successful, I would expect that maybe the price-gouging MFD technology paradigm is heading toward extinction in favor of reasonable (still more than 35mm of course) pricing.

This price is what I'd figured that Pentax was going to sale it for. Nice.

Finally a MF camera (crop sensor), true integrated live view and an advanced 27 point AF system ABOVE ALL WITH Liveview AF for true on sensor focusing.

Phase One:
Single AF point (last Firmware eliminated 2 AF points)
NO live view AF. Also you can't shoot in live view mode. You first have to shut off live view. Live view is not smooth. frame rate is quite slow and jittery. OK for focusing on a tripod with a tech camera and a static subject.

Single CF card
Back                 $ 35,000
Camera body     $  5,900

Pentax 645Z:
25 cross sensor and 2 non cross sensor AF points
Movable liveview AF point. True Live view at twice the frame rate of phase One.
You can shoot in live view mode,
SHOOTS video up to 60i
Dual SD card so you can shoot with redundancy just incase a card fails.

Camera              $ 8,500

Also the Pentax comes from and industrial giant Ricoh with a very diversified portfolio
and deep pockets

Phase One now belongs to bankers.

However a 44x33 sensor camera with out fast lenses is IMO a bit limiting. One of the benefits of MF is the type of shallow depth of field. Shooting a 44x33 sensor with a normal lens that is not faster than 2.8 is quite limiting as far as look goes. A D800 with a Zeiss Otus 1.4 Apo will IMO will do more than a crop sensor MF camera. 3mm added to each side of your sensor is not a game changer.

The lenses are very well priced too. You could kit out a lense package for a bit over $10K.

Any thoughts on the Pentax being 14-bit whereas the Hassy and P-One are 16?

Phase One and Hasselblad  CMOS 50MP cameras use 14bit files.

No sensor can fill a 16 bit file.

Phase One and Hasselblad use 14 bit files with the 50MP CMOS sensor because the AD converters are already built into the sensor. Sony knows perfectly well that 14 bits is all that is needed.

The amount of color tones that can be contained in a 14 bit file is 4.39 trillion

Things may change with Fuji's future organic sensors

They will creep along with tech cameras until Sony makes a MF Mirrorless
that can have tilt shift adapters for tech camera lenses.

The real reason for Phase One's high prices is to feed the dealers that market the hell out of "high end" MF because the profit is big enough for them to build a business around selling them. Phase One gear could be built for much less. Even the Schneider lenses are actually Mamiya except the tilt shift.

MF manufacturers love to use surface area rather than linear size.
Also have you noticed how they put the big number first... makes it sound bigger...

35mm is know as 24x36, but MFD is 44x33.

The problem is that resolution, depth of field and all the rest that counts is a linear function.

36 to 44 is only a 22.2% difference.

Pixel count is 38% higher than a D800

If I want a distinctive look of a larger format I'll shoot 6x8cm Film


Sensor sizes:

24x36 and 33x44

The price is amazing. Especially for something with 76 seals.

Competitively Priced
But the biggest thing that differentiates the 645Z from its competitors might be its low price for a medium format camera. When it goes on sale in June 2014, the Pentax 645Z will sell for $8,499.95. In comparison, the Phase IQ250 retails for $34,990, and the Hasselblad H5Dc is selling for $27,500.


So, if Sony does come out with a MF camera based on this chip we can safely assume two things - it will undercut the Pentax by thousands, and it won't come out for at least another year. But I still don't see Sony going after the MF market.

what is the sync speed on this, i heard only 1/125th? also the lenses... none of them are shutterLeaf that I could tell. Thats what is missing. I thought about waiting for this, for the price you can't beat it (in MF world).

But my main concern is that i would buy it and in 6 months regret it and then have wasted $15k (body, lenses, etc).

but damn, those rumors became reality.

besides price, the big feature i like with this camera is the focusing. Phase One has one point at the moment. Not a big deal, but coming from Nikon D800E where I had 51 points it was easy to keep the body stationary and move the focus points. Now I have to constantly move camera up, lock, and then recompose.

Fred, what's the size difference between this 44x33 sensor and a piece of 645 film?  From your diagram, it looks to be about 80% the size of the film ... is that about right?

1/125 was on the last (current up until yesterday) 645

Unsure of the new one.

So I've been shooting with Pentax cameras for 30 years, and I still have a Ricoh 50mm lens.

Do you think they'll give me one of these out of loyalty/professional courtesy/self-delusion?

Well, I thought it was worth asking...

I still have a non AF 645 with some lens, I really don't know if the old ones are up to the challenge of this new sensor but I don't suspect they are.

Still a $1500 price drop from the release of the "old" 645D and new technology - damn nice

Well, looks like a win-win for me. If Pentax doesn't give me one, I'll take all your 645 film stuff off your hands... lol

Nice to see  real competition in MF. The prices have to be around this price point as Nikon and Sony are delivering excellent cameras that do more, where the MF have only a few areas they may do better. I don't see the Pentax lenses super sweet as I do see with 35mm cameras.

My first film camera was a Pentax.  When I went digital I choose Nikon, because Nikon was the King Of Cameras.  When I went DLSR I went Canon, because Canon was affordable.  And Canon had better catch up, or I might be forced to make the circle complete!

This 3:4 ratio is a bit offing for me.  I'm used to the 2:3 (wider) ratio of the 24x36mm sensor that produces a taller portrait full frame.  This Pentax is going back to almost an 8x10 inch print format (actually 8x10.66 inches).  The current 2:3 (24x36mm) would produce an 8x12 inch print.

Since I do my own custom printing, I like the taller 17x25.5 inch size for portraits off the 24x36mm format.  They look better on the wall being taller.  Not too crazy about going back to the squarish variety of old 17x22.66 (or close to the 8x10 era.) that would be off this Pentax MDF sensor.  One would have to crop off the sides of the Pentax to match current digital frames and papers and even some wider screens.  I like to utilize the entire frame for printing.

44 vs 56mm  is a 27% increase.

Using MFD marketings area "illogic" 645 film is 61% larger if calculated by area.

With the right flash it can high speed sync.

Studio strobes are starting to show up with HSS.

That said there are a couple of leaf shutter lenses that go to 1/500th

I can highspeed sync on 35mm as well, and HSS looses powere from the strobe - I actually wanna be able to sync at 1/500-1/800 without jumping through hoops of HSS.

Unfortunately the only reliable system is the Hasselblad H upto 1/800th.

Phase One has leaf shutters. Mamiya had originally designed them to go to 1/800th
and also work on the AFD III. Phase One wanted them pushed to 1/1600th and out the window went reliability. Loads of posting about lockups, freezes and shutter failing early.

Another inexpensive option is the Fuji gx680. It can flash sync unto 1/400th.
Needs the either my body mod or the Kapture Group adapter box.

You can also get 1/500th with the Mamiya RZ.

However keep in mind that having leaf shutters is quite restrictive to lens design, especially if they are very fast leaf shutters. To be fast they have to be small.

OH MY is right... just priced the camera with two lenses that are must haves for me (the 33-55 and 80-160).  Cost came to OVER 15 THOUSAND DOLLARS!  I don't have a late model BMW or Mercedes just sitting around that I could sell... so I guess I'll be settling for the D800e... wink
