Large Format 24-105 equivalents

I’ve said in a previous post that I use my Canon 5D as a finder for my Ebony 45SU. Before now I’ve used an approx guess at 4x the difference in focal lengths in order to choose my lens. Today I tried out converting these settings by eye, trying the large format lens and then finding out the focal length that would be the equivalent in 35mm.

So the conversions I found were (based on a focus point of approx 4m )

The 80mm lens can be checked by using with long dimension of a 4×5 cropped 5D viewfinder to check the short dimension of the 80mm..

I’ll have to try infinity focus equivalents next.

Addendum:
Infinity focus tested – results updated in image
