Hello everyone,
I have a Pentax 645Z camera with less than 1,000 shutter activations. It is a wonderful camera and it compares very well with it's more expensive "brothers".
The only improvement I would like to see is a true electronic shutter. Apparently, this can not be accomplished via a firmware update.
The electronic shutter in the Pentax K-1 is very useful when I am doing macro photography image stacks of up to 400 shutter actuations.
This eliminates all vibrations.

Best,
Mike
400 stacked shots for 1 image! Between this and Ed Hurst's 4000 shots for a star trail image, my poor desk top computer just ran for cover and the Z said no way. What equipment are you using for such massive shots? I've done about 50 shots and it is slow, tedious, and tiring. Are you using an automated macro focus rail?

Thanks,
barondla

Hello Barondla,

Yes, I use an automatic macro focus rail that is mounted on a 24 inch aluminum rail. I am a very patient person, but to get all of the macro details in focus at the optimum aperture, I now use a 105mm F2.8 A Printing Nikkor lens or a 90mm f4 Tochigi Nikkor Rayfact lens that features variable magnification from .50X to 3.0X. It is perfectly Apochromatic and sharpest when used wide open.
The Printing Nikkors were originally designed in the late 1960s for copying movie film. They were $12,000 and finally discontinued in October 2019. I can only imagine what they would cost today.
Most stacks are 200 or slightly less shots. It is very easy to do with automated step motor. Lots of fun now!
Best,
Mike

Wow! Potent equipment. Are the Nikkors going on a K-1, 645Z, or something else? A 24" rail seems huge for macro work. Would love to see some of your photos and a pic of the equipment set up.

Thanks,
barondla

I would like to see the current k-1 functionality in the 645z body and sensor. How hard could it be? This would re-spark pentax as medium format takes hold again. There is something special about the image, I can't get it in all the FF camera's even the newest. Real like your eye see's, not flat. SR 50mpx and a full range lens. I loves this camera. I give us more please.

OoKU did mention already that it is on the plan(new 645 by Pentax/ricoh) now if it’ll be in 1 or 3 yrs no one know. There is new tech already coming -K3 III- and usually this new tech means there will be new model tier. Ricoh is looking to how to update their models to make them competitive, and that does take time. IMO they have not lost anything yet. And obviously they are not afraid of taking their time. If one want to have newest of newest update then go with what you find now. But 645Z seems good still and for sure there will be more of where those came from. They just have had so much to catch up wit aps-c,FF and lenses for those.

Don't think Pentax has lost medium format. Their camera and system are still competitive all these years later. What does Fuji offer, besides a 100mp model and mirrorless construction, that Pentax doesn’t? The Pentax system has many more lens choices and used lenses at far less expensive prices. Pentax will update the Z when they are ready. I'm not a pro and probably don't need a camera better than the 645Z. I putting money back just in case .

Welcome to the forums. I've only shot the ff K-1 and find the 645Z even better. Many have shot newer ff bodies agree that medium format looks more real. More 3 dimensional and less "brittle" looking. 645 images have a more relaxed look.

Thanks,

I agree, I loved having SR in my K-1 when everyone said lens stabilization was better, now you know they were all jealous since they all added it. But I want all the lenses to be SR in my 645z they should work the same. I don't mind the weight, it's the carrying and swapping that detract from MF. That's why I want a 45-300 f4.5-5.6. I like to hike with it. So if it had SR then lightweight glass would be welcome. If they do go short flange distance the they shouldn't loose the screw motor for auto focus on the adapter like Nikon did. I also want a focal reducer for 645 to pk. Why doesn't it exist? Then I could add two stops down to a 4/3rds camera too.

The Fuji models can, with an adapter, use the old Pentax glass, and there is also an adapter available that allows the Fujis to use Canon EF lenses, with autofocus. Reportedly, many of the Canon EF lenses work very well and cover the medium format sensor.

Fuji's own reps have recommended that folks transition to the GFX line by using their existing Canon lenses.
