Well, well, well... that was something different, for sure. I went to the "post" office right before i went to work, so that i would be able to make the first tests with this medium format adapter, when i got home.
And so I did.
Rotary Medium format adapter
Mounted it on the tripod, together with my widest Pentax 6x7 lens, the SMC 45mm f 4.5 lens. Then put the Canon EOS R6 (20 MP) into manual mode, and fixated the color temperature so that it wouldn't shift between the 4 frames. Each image is 90 degrees turned, centered around the optical axis of the much larger lens image circle of the 6x7 lens.

Then - you stitch them together in Photoshop.
A single frame, is equivalent to a 45 mm normal lens on a fullframe camera like the Canon EOS R6. But when stitched together, you get of course a wider angle, as they cover more. Now much that is equivalent I do not dare to say.
Maybe equivalent to a 28 mm wide angle at best ?
The only way for me to get wider images in this Vertex Medium format set up - would be another new adapter, but based on the Pentax 645 camera mount, together with the Pentax FA 35mm f 3.5 lens. But i have neither. I may add both, if i really, really like this kind of work - and it shows i do seriously good work with it. But for the time being - i stay with the Pentax 6x7 lenses.
By the way; Wide angle images with 6x6, often look less wide, compared to horizontal oriented images.

There is tiny niggles in the stitching sometimes
which i assume has to do with the automatic stitching features in Photoshop, which you can't really control much. But otherwise, the 4 images align well. (Or it was because i didn't disable the Image stabilization in the EOS R6 camera ! I'll disable it next time)
The Photo above
was taken with 6 seconds, at aperture ƒ8 and ISO 100.
In Photoshop i brightened the shadows a bit, but decided in the end, i would change the colors a lot more (desaturating them) just to adopt a different style. Corrected very lightly the perspective. Added a fake "Hasseblad 6x6 negative frame" around the photo. As well, run a very mild sharpening with Topaz Sharpening AI. hich isn't important in this photo above, because it is a lot smaller with 2000 pixels width, compared to the 7100 pixels in the original.
I notice that the Pentax 67 SMC 45/4.5 makes lovely stars out of highlights, already at aperture ƒ8 !
50 Megapixels in the classic "6x6" format
The result is a "6x6" classic digital image, made with a medium format lens, resulting into 50 MP when the Canon EOS R6 is used. With the Canon EOS R, it would result into a 75 MP image. An I may actually consider that camera.
In both cases - the resolution is waaaaay more than i truly ever use in my personal Diary here at XPan.se *LOL*
I like the handling style with the Vertex Adapter
What I really like about this way to work with the Vertex adapter - is that it is slower, and more manual. You have to think, and you have to concentrate. Way more than just taking "a shot" with a camera. Also the tripod itself, enables you to change your entire attitude towards what you are taking images of.
So, the whole handing is so ... well, very different to say the least.
Time wise it reminds me A LOT of dealing with a medium format camera, such as the Pentax 6x7 or the Mamiya RZ67 - because it takes time to compose and set things right before you take the image. I find it to be a very interesting, very different way, to do photography. And since I do have many Pentax 6x7 lenses... i thought, why not ?
A new genre
This new digital "medium format photography" - is a genre - which set itself apart from everything else i do in digital photography - that it actually feels fun, to work like this. The slow down for example, also can enable me to have "models", which have to stand still - and not move between the 4 frames (in case the model is centered in the frame, or his or her body across several frames.
But then this enables me again into that analog feeling and handing again, like i used to work in the studio at home.
Working with people... closer, with deeper contact
People didn't dance and fly around all the time. No, they stood still. And together we kind of worked ourselves towards positions that where beautiful to look at photographically. Slow movements, until it "felt right". And then the person froze / stood still until a couple of image were taken.
Now with the Vertex adapter, having to take 4 images which then will be stitched together - the model needs to stand still ! I absolutely love it. It creates a much denser collaboration between model and photographer. Actually working together - instead of the model just showing off, moving around like a chicken...
I like the old fashioned way. To take in the people you make images of.
Oh, it is so beautiful !!!!
Now I have to get Sal to work together with me... if he likes. And if he has time.
I am really intrigued
It's not that i need 50 MP. Or that noise is an issue with today's tools - which it so is not. Or the lack of sharpness, which also can be addressed. But the way to photography like this... well, well, well.... very different. And yet, with a feeling of recognition from the ol' studio camera days in the 90s.
I wonder how it feels to take images like that in daylight...
