The camera he used was a Hasselblad H4D-50 on loan from Hasselblad USA along with HC 100mm f/2.2 and HCD 28mm f/4.
My impression is that what he says is that:
Both cameras have issues with achieving optimal focus, but when accurate focus has been achieved the two HC lenses are not as good as the sensor in the Hasselblad. The Leica lenses are almost as good as it gets.
Lloyd has extensive experience with lenses, like Zeiss lenses on Nikon and Leica lenses on Canon using adapters and some absolutely astonishing quality lenses from Coastal Optics. That said, he has a limited experience with MF. He has done extensive testing with S2, and may even consider buying it. But he has issues with focusing. His experience with the Hasselblad is less immersive.
He has a lot of sample images, but no "A/B" comparison between the two systems. To put it shortly, in his view:
- The Leica optics are as good as it gets
- Achieving correct focus with either camera is a real challenge
- The Leica works better for the kind of work he does

I have revisited the DAP article. Lloyd used the 28 HCD 28/4 and the HC100/2. The 28/4 lens had a misalignment issue but the HC100/2 was OK. He found the HC100/2 to be very sharp at the center but lacking sharpness on edge and corners. He has actual pixel samples clearly showing the problems.
Now, he could obviously have two bad samples on loan from Hasselblad USA. He often finds issue with equipment. On the other hand Lloyd says that his findings are consistent with MTF-s published by Hasselblad and Leica. Lloyd has tested a lot of equipment and has a lot of input from Zeiss and Brian Caldwell (the designer of the Coastal Optics 60/4 APO lens), so he feels he is competent enough to interpret MTF charts.
Can you elaborate a little more? I understand you have to respect the copyright of the site owner; but in general terms what does he means by "that the S2-lenses were another class"? is he talking about build quality? image quality?.
From his site Loyd Cambers appear to have a good investment in Leica (time mastering etc). If that is the case, his opinions should be very, very relevant.
A simple question, in this context the "Hasselblad" is the H4D-40?
