Mechanical Relationship: Ndeupi hukama pakati pelenzi nevhavha?

Mumusangano, vatori vemifananidzo vanoshamisika apo, pakuona chivharo, ndinobvunza kuti: * “Malenzi api aunonyanya kushandisa? Wakapfura nechiedza makumi mashanu-kopeck 50mm f/1.8G kana nyanzvi inorema 70-200mm f/2.8 VR zoom?”*.

Zvinoita sekuti, lenzi inei nazvo? Ngatiratidzei kinematic yekubatanidza kubva mukati.

3 Zvinhu zvesimba zve optics pane shutter drive unit

1. Aperture Lever kushanda:Pane ese Nikon F-mount lenses (kunze akatevedzana E ane electromagnetic diaphragm) iyo shutter uye diaphragm mutyairi anokokwa ** neimwechete yemagetsi mota **! Rini Imwe neimwe furemu, lever iri mubayonet shaft chitubu-yakaremerwa inokwevera pasi iyo lens aperture. Pama lenzi akasimba ekare mutoro uri pamota iyi unowedzera ne40%.
2. Microdeformations ye magnesium chassis kubva kune inorema optics:Kana uchigara wakatakura D750 chitunha nacho ine 2-kilogram 70-200mm f/2.8 telephoto kamera yakasungirirwa pabhandi nemuviri (uye kwete negumbo retatu!), pasi pehuremu lens, microbending ye front frame ye bayonet inoitika. Izvi zvinogadzira kusarongeka kwechigaro chevhavha.
3. Electromagnetic diaphragm (E-mhando):Mazuva ano Nikkor E lenses (semuenzaniso, 200-500mm f/5.6E) bvisa iyo mechanical load kubva kune shutter lever nekuvhara aperture neyayo stepper mota.

Dhiraivha tafura yekutakura zvichienderana nerudzi rwe optics

Lens type	Nheyo yekudzora aperture	Shutter Drive Motor Load
Primes 50mm f/1.8G / 35mm f/1.8G	Mechanical leash (Chitubu chechiedza)	Standard (Minimal wear)
Kurebesa kureba 80-200mm f/2.8D / 70-200mm f/2.8G	Mechanical leash (Hard spring + Weight)	Kuwedzera mutoro pane gearbox
Yemazuva ano Nikkor E/Z-Mount Optics	Electromagnetic diaphragm	Minimum (Leash haana kubatanidzwa)
