I have no 'mottos'. I use the 80 and 50 most. Actually I carry them always together.
Ditto. In order of use 80mm, 50mm, 250mm, 38mm [SWC], and then 150mm. I do not do portraits often any more. If I am travelling and there are either narrow streets or tram lines, then I will tend towards wide angle more. Mostly I use the focal length for image cropping [read: compostion] more often then for perspective choice.
Warning!! Handling a Hasselblad can be harmful to your financial well being!
Nothing beats a great piece of glass!
I leave the digital work for the urologists and proctologists.
