Focus MechanismCONSTRAINED_RECONSTRUCTION: G2 translates toward the object while D5 decreases and D14 increases by the same δ at a fixed image plane. The 500.000 mm object-plane-to-image-plane states use solved δ = 0.954821883 / 2.944389620 / 9.421757313 mm at W/M/T. The US wide row prints 0.855 mm, which images 547.193 mm; M/T agree with 500 mm to source precision.
