for my $0.02 , the 645Z looks as about as good as it gets. BUT I can think of a few things it needs.
1 up the sensor to 75 mp.
2 add vertical and horizontal sweep panorama.
3 add 5 or 7 image adjustable spread HDR.
Finish it off by addressing and correcting every bug discovered since it's introduction. call it the 645Z 2 XL
#1 won't happen if Pentax sticks with CMOS. Sony Semiconductor is only making 44x33 sensors with 100 MPs.

Image stabilization

Is it a problem for handheld that the 645z doesn't have in body stabilization?

What do you mean by "problem". Please remember that people were shooting medium format before there was any such thing as image stabilization.

Because the 645Z is a beefy and larger camera, I find it easier to hold steady---I've always felt that about cameras going back decades. YMMV.

But also, medium format isn't really "action photography" gear unless you're doing fashion with strobes. And then of course you're freezing the action with the help of the flash. Otherwise, it's much more of a slower, tripod mounted sort of thing. That said, I have no fear using my 645Z handheld.

Would I like to have IBIS and would it help me with certain shots? Of course, and I'd love to see it in the camera (also because it is a doorway to other tech, like composition shift and PS). But not having it certainly didn't give me any cause for concern when I bought mine in 2014, and I was already using a camera with IBIS.

I was looking at buying one of the old medium format cameras, but the complaint from everyone was you cant shoot handheld. I presumed the 645z would have IS but it doesn't, which surprised me. I've been considering getting a used 645z, but the lack of IS is putting me off, and is pushing me more to the k1, as I am not the type to take a tripod everywhere.

You can shoot handheld.
I've been shooting the 645 and then the 645N handheld all day long since the late 80's. Yes, the 645Z is about 7% heavier than the 645N, but what I also only use primes, which reduces the overall weight vs. zooms. Is the K1 or any FF lighter? Yes. Is the KP or most APS-C DSLR lighter than the K1? Yes. But I consider the Pentax 645 series the lightest medium format DSLR available and it is not so heavy that I won't handhold it for hours while shooting. That heft also helps stability at lower shutter speeds.

I'm glad to hear that it is possible. What effect does having no image stabilization have? Do you miss a lot of shots? Loss of sharpness? (Nice images by the way. Your shot of the sleeping boy is great)


EDIT: Ah okay, I've just reread - you are purely a film shooter, so no image stabilization in those cameras anyway.

With 645, I only shoot film, but I do shoot digital with and without stabilization. I rarely miss a shot because I avoid shooting with slow shutter speeds unless I'm using a tripod.

The key handheld without stabilization is to avoid shooting below the focal length as a fraction of a second; i.e. 75mm lens while shooting a static subject at 1/75" or faster; 35mm at 1/35" or faster; 200mm at 1/200" or faster. The 645 has significant mirror slap induced blur, so I really try to maintain more like 1/250" as a minimum shutter speed handheld. If I'm not pixel or grain peeping, I can get away with slower shutter speeds, but the slower it is the more problematic with blur.

Most of the shots you're seeing in my gallery were shot handheld with 100 ISO for the color and 400 ISO for the B&W. Holding the camera correctly (left palm under the lens), bracing my left arm to my torso, exhaling on the shot, using continuous drive for multiple shots, and using standard to wide primes all contribute to maintaining sharpness and avoiding blur.

And regardless of film or digital, I don't care about my hit vs. miss ratio; I'm not worried about the duds as long as I get the one keeper.

You can shoot handheld with the 645Z, just be careful with your shutter speed, and know your limits (do you have shaky hands or not ?).
It is very easy to know if your picture is OK or not on the rear screen with 100% zoom in. You will see immediately if you have missed or not.

With correct technique you can easily shoot the 645D (and I presume the Z) at the reciprocal of the shutter speed with sensible lenses. However, the lenses are f/2.8 or slower, shooting in low light (1/30th f/2.8 ISO 100 etc) or indoors without flash will be more challenging (the Z's high ISO capability may help here).

As an MF film shooter, I have no issues shooting my P6x7 handheld at 1/30th if required with suitable lenses (probably not the zooms or longer primes).

If you're using IBIS regularly, your hand holding technique may need more care as camera shake may be a forgotten problem - it catches me out sometimes when shooting film - 1/8th at f/1.4 no problem... Oops. All this technology tends to make us lazy and reliant on it to a greater or lesser extent.

I'm so used to the stabilization of Pentax cameras since so many years... that I saw with a 645Z the photo were easily blurred and that I had to re-learn to hold steady, then it is ok to take handheld photo with it.
You just have to be more carefull.

Thanks for all the replies. Looks like I just need to be more careful if shooting medium format.
