Hasselblad X1D

Hasselblad X1D Format Equivalent Focal Length, Depth of Field

For a general understanding of format equivalence, see Format-Equivalent Depth of Field and F-Stop.

Format equivalance quick summary for the XCD lens lineup:

21.8mm f/4 ~= 17.9mm f/3.3
30mm f/3.5 ~= 24.7mm f/2.9
35-75mm f/n.n ~= 28.8 - 61.6mm f/n.n
45mm f/3.5 ~= 37mm f/2.9
65mm f/tbd ~= 53.4mm f/tbd
90mm f/3.2 ~= 74mm f/2.9
120mm f/3.5 ~= 98.6mm f/2.9
180mm f/2.8 ~= 148mm f/2.3

Versus 36.0 X 24.0 mm sensor. Nominal focal lengths as per specifications; actual focal lengths of real lenses are usually rounded.

There are no “fast” lenses in the lineup, even considering the equivalent lens speed. To match a Zeiss Otus 85mm f/1.4, we would need an XCD 105mm f/1.7*, which would be 2.5 stops faster than the fastest lens listed above, and the size of a super telephoto. So it’s clear why the XCD lenses are the size and speed they are.
