Building a technical camera – Part I

Step One of Building a technical camera

I have a new project: the ultimate DIY camera fun.

After much discussion with my buddy Satoru Murata, I decided to take on a project for the next few weeks. I will share with you some of the steps I will take into building a technical view camera… of sorts.

For those who are not familiar with such cameras, you can find a description here and a sketch below: http://en.wikipedia.org/wiki/View_camera

In a few words, this camera is made of a front board which holds a lens, and bellows that ensure the image coming from the lens goes without interference to a back element containing film or a digital sensor (there are also other types of capturing media but no need to go into such details here). What makes this type of camera special is the ability to move the front (and back) element in order to obtain large amounts of tilt and shift.

If you have been following me for a little while, you know that I use tilt and especially shift in my work, and sometimes using such special lenses in particular situations (for instance when you find yourself very close to the subject). For those who are into technicalities, another limitation of regular modern style T/S lenses is that movement happens at the front of the camera and not at the back. Back movement is however preferable because moving the front element changes the position of the image circle, and it usually is better to tilt (in particular) the rear element rather than the lens in order to avoid such changes in image circle position.

Now, you also now that I use Sony cameras for my work, as well as different sorts of lenses, ranging from modern and old Full Frame lenses to 30-ish years old Medium Format lenses (and I even also do Large Format film for fun). All these lenses are great, and MF provides a larger image circle, meaning that I can do larger movements than with FF lenses. Unfortunately, none of the adapters available on the market allow for full access to the MF lenses image circle, and some of them simply cannot be used, period (such as Mamiya RZ67). It is also impossible to use LF lenses on modern FF or MF dSLRs and backs.

So here is the idea: build a technical camera that will let me mount ANY (and I insist on ANY) lens (FF, MF, LF) on a modern digital FF mirrorless dSLR or MF back, and give TILT and SHIFT movement both at the front and back elements.

After some research online, I found that people can hack a Fuji GX680 body into doing something like this.

So I present you a new member in the family: a cheap (~$200 USD) Fuji GX680 III body which I will start stripping off its different elements in order to keep only the base body and moving elements.

On a different note, I’ll need to find this camera a name after it’s finished… let me know if you have suggestions! 🙂
