I'm really lost now. Could someone tell me how to convert between
those formats and 35mm?
35mm -> *istDx is  1.5x
35mm -> 645  ??
645 -> 645D ?? (I think it is 1.3x but not sure).
35mm -> 645D  ??
35mm -> 67  ??

Hi Thibouille,

I made this table a while ago:

        b       h       Dia     Normal Lens
APS-C   24      16      28,3    28      
135     36      24      43,3    50      
645D    45      34      56,4    55      
645     56      42      69,7    75      
67      70      55      89,0    90

Hope this helps,
