#Gx680 vs mamiya tiltshift manual#

Pentax 645 won't work with the longer camera-side adapter for deep grip GFX bodies, and neither will Mamiya 645. The catch is that shorter than 50mm is still mostly out of reach.

There are plenty of those floating around inside Mamiya RB67 lenses. You can either use them unmodified, like I'm planning to do, or you can put the GX cells in a Seiko #1 shutter. They apparently have a flange distance of 115mm, which puts the 50mm and 65mm Fuji lenses in play for someone shooting a deep grip GFX body.

The issue is the camera side adapter had to be longer to accommodate the grip of the 50S and other GFX cameras with a deeper grip, which pushes the GFX body farther away, and thus limits you to lenses with a flange distance of roughly 77mm (e.g., Apo-Digitar 80/4, also known as Componon-S 80/4).Д«ut that's where these Fuji GX lenses change the whole game. It's fairly simple to mount the adapter to a board, and you're on your way. I designed an adapter that RAF Camera in Moscow made to allow mounting a GFX 50S (at the request of a friend). Check this out:Д¬lick to expand.Up until last week I would have said you can get a 50S on a VX23D, but you have to be willing to live with 80mm as your shortest focal length. The flange distance appears to be 115mm, which puts the rear elements a long way away from the sensor, so even the 50mm lens (which is the only one that has a slightly smaller image circle) will be far enough that sensor cross-talk should not be an issue.ДЄnd what's really neat is that these lenses use a Seiko #1 electronic shutter, which has the same dimensions as a mechanical Seiko #1 - so if you don't want to use the big 'box' of the lens in its original form, you can remount the cells in a Seiko shutter and stick them in a lens board with a Copal 1 hole. On a 33mm x 44mm sensor, that's 35mm of shift in landscape orientation. I'm likely not going to need the shift potential the lens offers, but it's noteworthy that these things have a 120mm image circle (minimum). Fuji was really good at coatings when they made these their EBC coating should be effective. Computers were available for lens design, and the lens designs will be relatively simple because it's a rail focusing system. I'm optimistic because the whole system is relatively 'modern'. I'm waiting for the seller to box it up and get it shipped! Same with all the videos I've watched: people swap lenses without setting them up at specific positions.Д¬lick to expand.Ha, thanks Ed.

#Gx680 vs mamiya tiltshift manual#

There's no mention in any version of the manual (I've read all three!) about positioning the lens on the rail based on focal length. How would that work if it's not a fixed flange distance?ДЇor what it's worth, the user manual basically says 'stick the lens on and get shooting'. There isn't enough rail on the camera for the longer lenses to be symmetrical like a large format lens.

One key fact that drives my thinking is that the standard rail on the GX680 is only 65mm long, and all the lens, from 50mm to 500mm, use the same rail this includes the 100-200mm zoom. But the more I look the more it seems that this camera functions just like the Mamiya RB67, which has a fixed flange distance of 111mm for every focal length, and focus by rail.
