Having used both Hasselblad and Leica R systems I can tell from my own experience that Tech-pan in 35mm will give you impressive definition, rich grey-scale, and that 13x18 enlargements could look like medium-format enlargement out of a....100 iso say delta 100 (one of my favourite). But you will never, never have the subtle nuances as well as the width of the grey-scale (deep blacks with lots of details) you would get from 120 films exposed with medium-format Zeiss optics.(posted 9186 days ago)
