Oh my.

It arrived one day earlier - basically delivered by Cyberphoto over night, after I gave them the go late afternoon... it came to the post office next day here where I live. Amazing ! Well Cyberphoto is a good company with excellent service.


So, here she is

The "new" Fujifilm GFX 50s II Medium Format Camera in my hands, on my tripod.

When you adapt it with the rotating Vertex adapter with Pentax 6x7 lenses - you get now a virtual sensor size of incredible 65x65 mm - with 150 MP !

The uncompressed DNG RAW file size measures around 450-500 MB - each !



Me ?! So not a Fuji guy

Since I have never used a Fuji camera - i am totally unfamiliar with the camera setting. Oh my, sooo confusing in many ways - and not logic either. Kind of messy, like Olympus was for a long time until they change things to the better with the OM-1 model. Sony also was/is hysterically bad when it is about menus in many of their models. I have heard they change a little bit... so, i can't really tell, if they got it right, for the better, or still confusing.

Fuji could have done a better job, to be honest. Here Olympus with their Superpanel is absolutely stellar in my opinion. Second I find Canon to be very good. (Nikon I don't know anything about).

But OK. I have to learn anew - alot ! The Fujifilm way.

By the way - in this setting, stationary dealing with a tripod... it felt very cool with the Fuji GFX LCD screen - which you can set into all kinds of settings and angles. Because it tilts into all kinds of directions (while Canon, Olympus, Sony use just flip out screens).


Pentax 6x7 lenses

I have already set the Fuji up to be used with the big Pentax 6x7 lenses together with the Rotating Vertex GFX/P67 adapter. Man is that fun !! I love it every single bit. Now for the first time - I can see the ENTIRE rendering, their full image circle (after stiching) - which makes it fantastic. For the first time, it doesn't matter if used with 120-film in the 6x7 cm format, or digitally in the 7x7 cm format. All lenses now show fully their original designed focal length.

That's just stunning amazing !

I so did not see that coming just a few weeks ago. I had no idea that such a solution even exists. At least not in this rotating adapter kind of way.


You don't need a Fujifilm GFX

However, I also can say this: you do not need to pay a lot of money extra on top - for a Fujifilm GFX 50s II camera.

The Vertex adapter + Pentax 67 (or other medium format lenses of your choice - work delightful even with an Canon EOS R or any other fullframe mirrorless camera (with the right Vertex adapter and mount)

The difference is not that big, really. And you use the best center part of the 6x7 or 645 lenses - plus that when you already have a mirrorless camera, and some medium format lenses - the only expense is the approrpriate Vertex adapter - and you can already enjoy this new method.

I only chose the Fujifilm GFX 50s II - because i truly wanted to use the Pentax 6x7 fully, with their entire original image circle. But it was not necessary, really. It was my thing - my idea - that i wanted that. But the images with the EOS R where fantastic, also being all big medium format.

Wider view

Of course, all lenses now get wider, since I use the Fujifilm GFX 50s II with the Rotating Vertex method. Pretty cool, to see this happening, actually. I mean how the lenses now show a wider perspective, compared to when I used them with the Canon EOS R camera.

The big, bulky 6x7 Pentax Takumar 55mm f 3.5 becomes now a pretty wide lens - which it wasn't before. While the wide Pentax 67 SMC 45mm f 4 becomes very wide ! Not to mention the cazy Pentax 6x7 35mm f 4.5 Fisheye lens - get's really, crazy wide. And yes, the borders get all mush, especially after I defish the image, making lines straight.

But - I noticed that i liked the results, both with Fisheye effect, as well defished (on the Fuji GFX 50s II camera and the Vertex adapter). As you can see in the image comparison above - the difference is quite pronounced ! I might have stood a little bit more backwards in the wider image. Yet still - the view is definitely wider when using the Fuji camera with its overall taller sensor.


Here's another example

but with difference lenses: The 55mm lens is now a notch wider with the Fuji GFX camera, compared with the 45 mm & Canon EOS R + Vertex adapter.

Cool !

Makes the Pentax 6x7 wide angle lenses more useful now !! I assume that I don't really need the Fisheye, unless I want to go crazy wide. How much that will be useful outdoors, while looking natural or not - i'll have to test out, of course.

But the Pentax 6x7 wide angle lens, should now be a keeper - because it renders with straight lines - and I don't need to morph correct the borders. Therefore the borders should be a lot sharper, compared to how the borders come out with the defished Fisheye.

Take notice

in the last photo how the Pentax 67 SMC 45mm f4 lens now has the same width with the Fuji GFX 50s II camera - like the Fisheye 35mm f 4.5 has, when when used with the EOS R camera (+ Vertex adapter).

It means, in order to get a nice wide angle view using Canon EOS R + Vertex you get it with the Fisheye 35mm f 4.5 lens.

But with the Fuji GFX 50s II -and the Pentax 45mm f 4 lens - you get the same wide view - making it a better candidate for wide, natural views - and without having to defish anything.


(Vertex adapter) • You have to lock certain criterias in the camera

When working with the Vertex adapter, you need to lock the color temperature - so that all 4 images you take, will have the same colors. Otherwise the stitching process will generate funky looking images.

Also shutter speed needs to be fixed (manually adjusted to one value). And IBIS (image stabilization) has to be turned off. It is a good idea to turn on the self-timer, too - so that any vibration ebbs out before the image is taken. I usually set it to 2 seconds.
