Large camera lens comparison chart
Angle of view is the
most accurate way for comparing lenses and formats. The Focal Length Equivalent
Chart is to aid us with a very simple comparison to a format that 99% of us
have graduated from. The 35mm comparisons are very close. The angle of view was
measured from the actual exposed aria of the negative whenever possible. This
is why a 6x12 and a 4x5 have the same position. (120mm is the actual exposed
with of a Fidelity cut film holder)
