May 5 2022 status: I have parts to make 2 more. Sadly, I need to increase the price.

All initial orders from the first batch have been completed.

Introducing Hsq, a motorized, one touch eject, infinity focus enabled Instax Square film back for Hasselblad V system cameras (except ELM, clearance issues).

Use any Hasseblad lens and/or Macro tubes, no need for anything else (like a front mounted filter).

Features a full metal mounting plate and a Hasselblad style dark slide – you cannot release the shutter unless you remove the dark slide. Did I also mention the photos eject up and they have the correct, chemistry at the bottom orientation?

Check out the corresponding Rescue Me section for a use demo video. I need to replace the product pictures, I’ve made some small changes (added a beefier external on/off switch and a serial number inscribed motor cover.

Batteries (2x CR2) and one 10 frames Instax Square film cartridge included.

These were made in a very limited run (6 units in the initial run) and were available only on order to build. I am now out of stock and contemplating a new order of fiber optic plates from the manufacturer in order to produce more. Check/subscribe to the blog for news.

Why is this so expensive? In order to reach infinity focus on these, one needs to move the image plane quite a bit (there’s only a few mm-s from the metal mounting plate to the image plane in a Hasseblad V back). Some builders use a negative lens attached as a filter to the lens.  I use a custom ordered Fiber Optic Plate to transfer the image from the focal plane to the instax film surface. It’s expensive.

Due to the design, there’s an approximate 1 stop light loss in the fiber optic plate, so please rate the film at ISO400 outside, ISO 320 in subdued light and ISO 500 in very bright Sun (instead of the ISO800 box speed). Do test though, one frame should be enough to tell.

The back has a 5 year parts and labor warranty, I’ll pay for the return shipping to you. This does not include accidental damage (dropping it may break/chip the internal Fiber Optic Plate for example).

Shipping if free CONUS and Canada. For other destinations, the shipping calculator should be accurate. If you get some outrageous shipping quote for another destination, do contact me and I can send you an invoice with the proper amount for shipping (about $50 priority mail, about $75 express mail).
