NONS Camera Instax SQ back for Hasselblad V-System...

Godfrey said:
If you ordered a NONS Hasselblad back, it has to be the current generation model. The new model is just announced and they're taking pre-orders for it. 🙂

By the way: InstaxSQ film is nominally rated at ISO 800. However, I've found through a bunch of shooting and testing that ISO 800 proves a little optimistic as it tends to produce somewhat underexposed prints (at least with my Hasselblad V system lenses and Sekonic L-358 metering). I've found that rating the InstaxSQ film at ISO 640 produces more consistent results ... occasionally just a trifle hot for some scenes, but generally better exposures overall for most of what I shoot.

I suggest you experiment a little bit to find the ISO setting that works best for your photography.

Oh that's crap, the new one does not work with the SWC according to the website. They still show both, I just rashly assumed that meant both were available.
I may have to email them to see if they have any of the first versions left.

Right - I decided I wanted the universal capability of the current one. This should be fun!

As far as I know, they haven't discontinued the original model.

The new moderl back can't work with the SWC because the back focus of the Biogon 38mm lens does not allow moving the film plane rearwards by 3-4 mm, nor does the SWC have a useful mechanism to focus the lens critically without swapping in the ground glass back. The original model can work with the SWC/M because it maintains Hasselblad's original film plane location.

This is another reason why I think they haven't discontinued the original model. But it would likely be worth a note to ask the question and get confirmation.

One thing I immediately noticed - using a strap with this back may be risky, it will apply a lot of rotational force against the back.

Mine is charging right now.
 
InstaxSQ film is supposed to be rated at about ISO 800, but at least with my light meter and the Hasselblad, I've found exposures based on ISO 800 are about a third to a half stop dark. Given the breathtakingly limited latitude of instant print film, I decided to try to do a definitive ISO check using the Hasselblad 500CM and NONS InstaxSQ back.

First exposure was at a guessed ISO 640 and turned out just about right:


InstaxSQ B&W - Exposure Test, Color Checker​

So, ISO is closer to 640 than 800. That's about what I expected. So I engaged my portrait model (hey, his rates are low and he's cute ...):


Pride Bear, Portrait​

Right on the money! The meter read EV 11.9 (incident reading). The camera setup included the Sonnar 150mm f/4 T* lens and a 32mm extension tube to bring focus in to about 38 inches, so I opened up just a little from that meter reading.

Here's the setup on my dining table:

Fun fun fun! 🙂

This is great - you saved me and others money! Thanks for doing this - I’ll start at EI 640.
