The 23APO requires the use of an appropriate Hasselblad V-mount lens adapter for use with the target camera. The 23APO is not designed to be used on Hasselblad cameras due to mechanical incompatibilities.

So... they made Hasselblad-mount lens, that can't be used on a Hasselblad?

But with the Hasselblad adapter on all FF APS-C .. Cameras
And for some formats a shift adaprer is available


A high performance full mechanical 23mm Shift lens should be fine

So... they made Hasselblad-mount lens, that can't be used on a Hasselblad?

The choice sends motivated by the long flange focal length Which makes it possible to fit to almost any camera (except ironically the one with that mount natively) and the availability of existing adapters.

The 70 mm image circle could also encompass the 645 film focal plane size so long as no offset were used.

I'm sure this lens falls into the category of boats and exotic cars -- if you need to ask the price, you can't afford it.

And if one could afford it, is there a Hasselblad V adapter to 645 body flange?

It would be nice if the Arsenal fisheye had a published MTF chart one could compare.

based on the charts on the lens' web page. Distortion looks hard to correct, but maybe that's just me...

Here's the text in full from Steven Lee, founder of NWS, in response to my enquiries....seems constructive, and similar to the primary target market identified by Hartblei/Hcam in Germany, but they do seem to be interested in the needs of the MF market too....watch this space....

Dear Mr. Moore,

Thank you for your interest in our 23APO and Akrobat products.

Before we began defining our product specifications, we researched the market and our intended target customers extensively to make sure we can offer solutions for unmet market needs at prices that customers will pay. Then we designed each with price targets that are commensurate with performance and market expectations. We plan to release these prices once our prototypes have been fully vetted by beta- testers and our factory partners confirmed their offers based on final specifications.

One note about your choice of the Pentax 645z is that it has quite a deep body so even with the flange focal distance of the Hasselblad V-mount at 74,9mm, there is less than 5mm margin for any adapter solution. There are on-axis adapter solutions available but this limitation does not allow a 1-axis shift adapter or the Akrobat to work with it as a back – there is simply insufficient room. Given our choice of the Hasselblad V-mount, the 645z may not be a mount we can readily serve if tilt and shift are absolutely required.

The 23APO and 110APO were designed primarily to serve 24x36 FF cameras, even though their image circles cover some MF formats. We did so because there are many more FF cameras, and they are very much in need of a high resolution ultra-wide-angle with edge-to-edge sharpness. For many working professionals with Art Director clients, they have mostly relied on the more profitable FF 5Ds/5D Mk IV and D850 than any MFDB. In fact, until the GFX and the X1D came along, there were few reasons to believe that MF would ever thrive again beyond the few very well-heeled who buy IQ3 and 4s.

Since our public announcement about a month ago, we received tremendous positive feedback from the MF market and it appears there is an obvious void we can fill. You voiced similar needs – an ultra-wide-angle that fits MF 33x44 cameras. We take these comments to heart and are considering how best to meet these needs, and will announce next steps when we arrive at possible solutions including new offerings.

For major events such as new products or events, we issue press releases. We plan to release progress updates on our website as soon as we are confident and ready so please check back once in a while to get the latest news. To keep you up to date, your name is added to our mailing list.

If you have any questions, please feel free to contact any one of us at info@nws-instruments.ch , or write me directly. We will do our best to answer your questions.

Thank you again.

All the best,
Steven Lee
