The other beauty of the rotating, digital Vertex method is, that via Lightroom Classic, you are then dealing with ONE digital RAW (DNG) file, as if it was shot with a 46x46mm or 65x65mm sensor camera!

This makes everything feel, as if you just transfered your Pentax 6x7 lenses into a digital equivalent camera, so to speak. I find that simply amazing.

I never thought this was even possible.

Well the Vertex rotating adapter hasn't been out for such a long time really. I believe Fotodiox introduced it in year 2021 - but I never heard about this kind of rotating adapter method before. I stumbled on it by accident... I can't even remember exactly how... Ah, because of their earlier, more quirky adapters from 2013. (I don't know the exact name of those).

Which was/or is available for 4x5" format cameras. The new iterations I see on their homepage, are now possible with various DSLR cameras - but can not be used with 4x5" field cameras (like the Toyo Field 4x5 AII, the model I have). And the adapter only works with 120 mm largeformat lenses and longer. That has probably to do with the shorter distance of wider lenses, not giving enough room for an adapter to be used at infinity.

I didn't bother, albeit the idea is still very interesting. Yet, how often do i go out with a 4x5" Largeformat camera ? Almost never.

But it made me bump into the Vertex adapter for Pentax 6x7 lenses... That is how it all started.


Vertex adapter for Mamiya RZ67 lenses - not available

Pity, also, that the Vertex rotating adapter this far isn't available or even possible, with Mamiya RZ67 Sekor Z lenses. Now that is truly my primary medium camera for film. But its lenses are electronic... (albeit it should be possible, because you can manually close the lens with the level - but you need to "fixate it", wither with a tape or something else. A roundabout approach - but it should be fully possible to use Mamiya RZ67 Sekor Z lenses !! The electronically steered central shutter in the lens, isn't used when you adapt the lens on a different camera, since you use the camera's shutter.


File sizes...

Now having a mega large 125 MP RAW file (when using Fujifilm GFX 50s camera) - it a lot of megapixels. Waaaay more than what is needed for this kind of photography. But it isn't a problem either.

Since you get a single RAW file in the end of the process - you can create a RAW file that is smaller, let's say 50 or 75 MP instead of 125 MP. Nobody needs such huge DNA files with the Vertex method awhile using not painstakingly pin sharp Pentax 6x7 lenses like those made by Fuji (unless of course, you use Topaz Sharpen AI or Photo AI which increases the fine details). But still - 125 MP is way over the top.

I think 50-75 MP is more than plenty - and it is more easy to handle with further post processing, as well for storage.

When i first started with the Vertex method, i created TIFF files - but ended up with almost 500 MB files for every single photo (made via EOS R camera). Then i thought of Lightroom Classic, and realized that it can create a DNG RAW files from the 4 stitched images. The weight was now 250 MB instead.

Good enough for me.
