100MP Sensor released

Fuji just dropped their 100MP sensor body.

Any word on the street if Pentax will look to utilize this sensor in a 645 body?

645 is way more overdue.

No.

But did you read the interview with the executive at CP+, 2351HD?

It is still crop 44*33. Pentax could emulate it by introducing IBIS in the 645. I would rather see a 645 with a larger 53.740.4mm sensor.

Twice the MP buys you 40% more resolution. Not as big a deal viewed that way.

I would much rather see a 100MP full frame 645 sensor. Pentax's system has the lenses for it. Fuji doesn't.

Apart from the DA 25mm, which has a built-in crop hood.

This is the kind of camera you better carry with one strap and a backup strap attached to your belt. At $10 000 imaging knocking it on something, getting heavy rain, slipping on the floor and falling with the camera in your hands. Does it do pixel shift and 10 frames per second? No 8K video?

The optics are full frame. Changing the hood is easy.

I believe Pentax to be well positioned here

Several pertinent things:
  • They could use this new sensor in their Z body w/o body mods
  • Pentax has IBIS tech, and room in the Z body for it, no body mods necessary
  • Pentax has PS tech
  • With this camera, Fuji has no size advantage!
  • Pentax remains ready to make the jump to "FF 645"; Fuji is not---they are all-in with "crop" 645.
  • Pentax has already been doing some re-releases of their lens line downstream. No, they are not total re-designs, but they are new production with new coatings. So, that's something they could translate upwards to the 645 line.
  • In the downstream lines, a couple of very good new lenses have been released. No, it's not a dozen new ones, but the ones that have come are very good, and there are a couple more on the horizon. It's not like they have forgotten how to make good lenses, so I have hope for 645 (please re-do the 45!)
So, I'm guardedly optimistic. I think their stated (in 2 interviews from CP+) wait and see on 645, but still committed, is sensible for Pentax. When David faced off with Goliath, I'll bet he waited to take his best shot....

The thing to remember about shifting this sensor is that larger dimensions increase the mass of the sensor unit enough that a more powerful system is required to move the sensor, especially if IBIS is to be as responsive as with smaller formats. If this more powerful system creates a lot more heat, that in turn requires further modifications. Why else would the HD 90mm (the most recent Pentax 645 lens?) have in-lens shake reduction? Combining supercharged IBIS with double the data per image and Pentax's 645 camera requires a giant leap in processing power and battery power (not even considering the higher demands of processing 100MP Pixel Shift images). After all the complaining about higher pixel density in smaller formats in order to get more megapixels, where is the visible benefit of 100MP over 50MP in a 44x33 sensor? Be careful what you wish for.

Well, I'd say 2 things. There's room in that Z box. The K1 managed both Ibis and PS with a 36mp sensor and the standard battery in one of the most compact FF OVF bodies out there. My battery life in that camera is pretty good. The point is well taken about the additional processing power required, but my Z's battery life is now excellent, so a drop to OK wouldn't bother me too much. And I'm not sure that the 90's OIS had much to do with heat----I think Pentax felt they needed to offer a stabilized alternative and that was the quickest way to go about it.

To the other point, I think that the Z's output is quite excellent and truly sufficient for so many purposes. But for certain things, and upgrade would be desirable, and those certain things happen to be things I do professionally and personally. But they are special cases, and in that rarified realm of such.

For me, it would be a tough call if it was an either or situation: "FF 645" at 100mp, no IBIS or PS, or "crop 645" at 100mp with IBIS and PS. Very tough call.....

It's not clear to me that 100MP in the crop MF format would be better than an improved 50-75MP sensor with PixelShift in 645 format.
