Mamiya RZ67 Pro IID + Phase One IQ4 | MEDIUM FORMAT Dream

This video is very likely the only comprehensive tutorial on YouTube on shooting the Mamiya RZ67 Pro IID with the top-notch Phase One IQ4 digital back with a 150MP Medium Format sensor. I was working on this video for a long time so I hope you enjoy it :)

Please drop me your comments with your own thoughts and experience. And if you found another way to make this combo working despite Phase One Support saying "its not possible", please let me know in the comments. At least I found a way to shoot the Phase One IQ4 on the Mamiya with well known Mamiya lenses :)

The video has a file size of 3.5GB so please be patient when you jump to chapters and please give the video a moment to load (depending on your internet bandwidth and speed).

----------
"Oscar B" shared (thanks for that!) in the comments another way to shoot the IQ4 on the Mamiya which I want to share here so that everyone finds it.

Shooting with the leaf shutter in the lens instead of the electronic shutter on the IQ4 can have advantages to avoid rolling shutter effects or for higher flash sync speed. Here is how "Oscar B" suggests to do it - and I am sure it works although the workflow is not as straightforward as shooting with the electronic shutter on the IQ4.

Set-up the IQ4 for a longer exposure time with electronic shutter (a few seconds, in any case long enough for you to have time to operate then within these few seconds a mechanical shot on the Mamiya with the leaf shutter and mechanical shutter button.

Then, within the time interval of these few seconds (set-up on the IQ4), shoot the camera manually and with leaf shutter with your target shutter speed, e.g., 1/400sec.

Although the digital back will record an exposure time of (the before set-up with e-shutter) several seconds, the sensor in the IQ4 will only be exposed to light as long as the mechanically set-up leaf shutter on the Mamiya lens is open. So the image will be exposed with the correct amount of light despite the fact that the IQ4 was set-up for a much longer exposure time.

Metadata/EXIF will be wrong in the image data but the image will be correctly exposed and triggered by leaf shutter (within the e-shutter time window set-up on the IQ4). On tripod this will work quite well, and this camera/lens/IQ4 combo is typically anyway mounted on a triopd and not operated in a free-floating hand-hold way.
