hi everyone.more question needs your help
i readed the pdf issued by phase one which listed several hassel lenses usable with 645df as follows
Lenses usable in combination with Phase One Multi-Mount
Carl Zeiss CFi 30 f.3,5 3 hasselblad V
Carl Zeiss CFE 40 f.4,0 3 hasselblad V
Carl Zeiss CFi 50 f.4,0 3 hasselblad V
Carl Zeiss CFi 60 f.3,5 3 hasselblad V
Carl Zeiss CFE 80 f.2,8 3 hasselblad V
Carl Zeiss CFi 100 f.3,5 3 hasselblad V
Carl Zeiss CFE 120 f. 4,0 3 hasselblad V
Carl Zeiss CFi 150 f.4,0 3 hasselblad V
Carl Zeiss CFE 180 f.4,0 3 hasselblad V
Carl Zeiss CFi 250 f.5,6 3 hasselblad V
Carl Zeiss CFE 350 f.5,6 3 hasselblad V
i am going to buy a portrait lens,one amount 120 150 or 180.my question is why only cfe 120 listed here but no cfi 120.and on contrary,only cfi 150 but no cfe 150 listed here.is there any substantial reason?so far as i know it,the only different between cfe and cfi lenses is the lens code.
thank you in advance!
