S-Mount Lenses User Guide V1.1.0
S-4.1-F3-5MP-T1-2.5
Lens position at infinity (approximately)
defines values for the position of the lens when focused to infinity. We
recommend using a minimum thread engagement length of 1.0 mm (two 360
degree turns). Below this length, lens mounting is not stable enough.
