I am a close-up photographer and have a number of cameras systems, Nikon, View Cameras, and Hasselblad X2D. I’m always looking for a very thin extension tube so that I can use to bring more lenses closer.
In general I don’t believe in extension tubes because they degrade a perfectly built lens, but if I am going to use one, as good as many of the Hasselblad XCD lenses are, then I want it to be very, very thin. That way, at least in the center, there is as little degradation as possible.
And as good as the Hasselblad XCD lenses are, I could only hope that someday Hasselblad would come up with a thin extension tube for the XCD lenses, yet I dared not think it would actually happen.
This 9mm is about as thin an extension as physically possible for such large lenses, more than I could hope for, and it maintains AF and Auto Exposure Functions. It took a while to show up, yet it is very well made and perfect for many XCD lenses like the 30mm and others.
I realize that "getting close" is the reason for the extension tube. Just curious what the farthest subject distances are with the 9mm tube for your 38 / 80 ... i.e. 1 ft, 2 ft, 3 ft, etc.
Or, is it just a matter of only a few inches diff between nearest / farthest focusing range?

I did a quick test with my 55mm V lens and a measurement tape and I could focus between 29 and 53 cm (roughly) with the extension tube, using the same test I got 44cm as the MFD without the tube so it overlaps this distance. I checked the data sheet for the lens and the MFD was given as 45cm so I wasn't to far off in my measurements.
