>>3372253Fullframe: 36 x 24mm = 43,267mm diagonal
Hasselblad H6D-50c / X1D-50c / Phase One IQ3 50MP is quite similar
Sensor: 43,8 x 32,9mm = 54,78mm = 0,79 cropfactor
Hasselblad H6D-100c / Phase One IQ3&4 are quite similar depending on MP
Sensor: 53,4 x 40mm = 66,72 = 0,65 cropfactor
50mm fullframe requires 63,23mm and 76,92mm on above mf systems
The blur circle ( C = Aperture Diameter A x (Distance S1 - Distance S2 / Distance S2) is independend of the focal length.
So for the same framing all that matters is paerture diameter which has to be the same on both shots to match.
F-stop is Focal length / aperture diameter:
50mm / 1.4 = 35,71mm diameter
63,23mm / 35,71mm = f1.77 or 1.4 / 0,79 = f1.77
76,92mm / 35,71mm = f2.15 or 1.4 / 0,65 = f2.15
If you look at Hasselblad or Phase One's lens lineup you wont find many lenses this fast. 2.8 and slower are the majority.
1.9 and 2.2 being the fastes Hasselblad has to offer. Not to forget 1.4 isnt even the fastest FF has to offer.
