p.3 #1 · 100mm non-L macro

Thanks for posting the field of view test!

If the distance to the tape measures from the focal plane is 17 inches (432 mm) and ...

... we approximate the lenses as "thin lenses", then by calculation from the image data ...

The macro lens has a focal length of 88 mm at that distance.

The zoom has a focal length of 66 mm at that distance.
