Hi, this is my first post here.
I would like to show off a project i built around 3years ago. It has had a lot of use so excuse the current condition of it. I designed & built it with my own hands...
In a nutshell it is a camera body built out of aluminium which i mount a Sony A7 (will also work for A7r\Mk 2,3 & 4) on the sliding back & mount any Mamiya RZ67 lens on the front end,
which has a bellows\focusing-rail to focus (50mm ULD in pics)...
I basically compose & focus the image using the Live-View of the A7 & set critical focus plus adjust the lenses floating element by the magnified live view on the lcd.
I then set the sliding plate to one end & take each exposure (in between sliding the back to the next frame). It is calibrated so that each frame (7 in total) has roughly a 40% overlap for stitching.
I can then easily merge the images in PS just using the built in reposition photomerge tool. There is no post cropping that needs to be done & zero geometric distortion as i am just capturing the large
image circle of the RZ67 Lens in multiple 35mm frames.
So far, i only have the 50mm ULD which is equivalent to an ultra wide lens. And i also have a 140mm Macro. I have been very impressed with the resolution\detail of the Mamiya lenses.
Next upgrade will be getting a A7R Mk2, i would love the MK4 but the bank wont allow it atm. lol
Anyway just thought i would share it, here are some pics of the setup & also some shots taken with it.
Cheers
