With the same technique i use between Canon EOS R, the Vertex rotating adapter and Pentax 6x7 lenses - which is equivalent to a 46x46 mm sensor. The same with a Fujifilm GFX 50s medium format camera, would result into an equivalent sensor of 65x65mm.

That would mean, the latter can utilize the ENTIRE IMAGE CIRCLE of the Pentax 6x7 lenses. It would mean, that the results are almost the same like when you use Pentax 6x7 lenses with film. Showing the entire focal length, like it was designed for originally.

This of course sound utmost interesting to me - so i might look out for a second hand Fujifilm GFX 50s camera next spring, when the prices drop further. Because Fuji in Stockholm, is presenting its latest flagship model to the world, the Fujifilm GFX 100 II camera. People will abandon their old Fuji GFX 50 camera (2017) even more... and the prices drop.


What's up with a Fuji GFX 50s camera ?

The biggest difference is, that it has by design a larger (than fullframe) sensor, measuring 33x44mm, with totally 51 MP. And you can use medium format lenses directly with help of an adapter - albeit the crop factor will still be an issue, especially with the larger Pentax 6x7 lenses. But that's the same with the native digital camera, the Pentax 645z, too.

However, I thought that with the rotating Vertex adapter made for Fuji GFX cameras, the larger sensor and 4 overlapping images, create a larger sensor frame, overing the entire 6x7 lenses. By that, you really get the look of how photography looks like digitally, directly though a Pentax 6x7 lens all the way to the borders.

I find that extremely interesting - even if the usage is limited, compared of taking one image at the time (e.g. moving subjects). Yet, with a Fujifilm GFX 50s i can do both, of course.


A digital Pentax 6x7 camera

Albeit to be really honest. I am only interested in using the Fujifilm GFX 50 as a "digital Medium format camera á la Pentax 6x7". That is my primary objective.

Everything else... I do with my other cameras.

The Pentax 6x7 lenses would also become wider again, compared to how they perform now, when i use my Canon EOS R with the rotating Vertex adapter.

Cool !!!
