Three eras. Three native machines.

This exported unit combines the SX-70's lower folding chassis with the door used to load an integral-film pack. The rigid base supports the folding mechanism, while the closed door keeps the cartridge seated and the film path light-tight.

The rear shell forms the structural enclosure around the film-pack chamber and the path from which the pack's dark slide is ejected. It protects the cartridge area and helps hold the film at a repeatable plane behind the folding optical assembly.

Eight modeled pleats represent the opaque bellows that seal the changing space between the front standard and camera body. A folding camera needs this flexible light barrier so the lens can deploy without admitting light around the intended image path.

The deployed front standard is the rigid board that carries the fixed lens and shutter assembly at the front of the bellows. Its locked position establishes the optical geometry needed for the SX-70 to focus and expose integral film.

The four modeled struts represent the linked folding mechanism that raises and braces the front standard and viewing assembly. Their pivots let the SX-70 collapse flat and return to a stable shooting configuration when opened.

The reflex mirror redirects the taking lens's image into the focusing path before an exposure is made. Because the SX-70 is a single-lens-reflex camera, the photographer frames and focuses through the same 116 mm lens that exposes the film.

The focusing screen presents the lens image for visual focus, while its Fresnel structure distributes light across the finder. This optical screen is part of the SX-70's folded SLR viewing path and is cleared from the taking path during exposure.

The exported viewfinder combines a pop-up hood with the eyepiece through which the focusing screen is inspected. Its folding construction preserves eye-level composition while allowing the camera body to close into a thin package.

The front release and its pivoting linkage start the SX-70's automated exposure cycle when pressed. The linkage is distinct from the leaf shutter inside the fixed lens module, avoiding a second representation of the same exposure gate.

The timing board coordinates the camera's reflex reset, motor drive, film picking, and print ejection after an exposure. Reduction gears trade motor speed for enough torque to move an integral-film sheet through the developer rollers.

The paired rollers receive each exposed integral-film sheet as it exits the camera. Their pressure ruptures the reagent pod and spreads processing chemistry across the image area, so clean and parallel rollers are essential to even development.

This exported hardware unit groups the tripod socket, folding latch, and chassis hinges. The socket anchors the camera to a support, while the latch and hinges govern the body's mechanical opening and closure.

The front bezel is the structural rim surrounding the exported 116 mm objective. It protects and locates the front of the fixed lens module without acting as an interchangeable lens mount.

This exported singlet uses exaggerated convex curvature to make the front objective legible in the educational model. In the camera's four-element 116 mm f/8 lens, the front optical surface begins gathering and refracting light toward the film.

The focusing cell is a mechanical carriage around the front optical assembly, modeled with a helical exterior. A helical converts the photographer's focusing input into controlled axial movement that changes the lens-to-film distance.

The model represents this correction group as a cemented doublet behind the front objective. Grouping refracting surfaces lets a compound lens share optical power and reduce aberrations that a single element would leave uncorrected.

Five joined overlapping blades visualize the lens's mechanical exposure gate in this export. Leaf-shutter blades open around the optical axis and close after the interval selected by the automatic exposure system.

The aperture iris forms a variable opening that controls how much of the lens's light cone can pass. Its blades are a moving mechanical stop, while the SX-70's exposure electronics coordinate the selected opening with exposure time.

The photocell and its small board form the exported sensor module for the SX-70's automatic exposure system. It measures scene brightness rather than making the photograph, allowing the timing circuit to adjust shutter operation without a manual speed dial.

The rear optical group represents the field-correcting surfaces nearest the camera body. These elements complete the lens's convergence and correction before light enters the SX-70's folded reflex path.

The square flange seats the fixed optical module against the SX-70's folding front standard. Unlike a user-changeable bayonet, this structural interface keeps the lens and shutter permanently aligned to the camera body.

This exported unit combines the shutter linkage with electrical terminals at the rear of the fixed lens assembly. The coupling transfers exposure-control action, while the contacts provide the electrical connection required by the camera's integrated exposure and flash systems.

The rounded shell is the main structural enclosure for the µ[mju:]-II's 35 mm transport, finder, flash, and fixed lens. Its compact capsule form and sealed joints support the all-weather construction described by Olympus without implying that the camera is waterproof.

The molded front fascia is the splash-resistant faceplate surrounding the lens, finder, flash, and sliding-cover path. As a structural skin, it locates exterior openings and helps shield the internal mechanism from handling and weather.

The open cover exposes the lens and represents the clamshell control used to switch the camera on for shooting. Sliding it closed protects the front optics, so one mechanical action serves as power control and lens shield.

The guide rails constrain the cover's lateral travel, while the spring and interlock give that movement a defined end position and switching action. This mechanism lets the protective shell operate the camera reliably without a separate exposed power lever.

The collar surrounds the fixed lens barrel and provides the seat for its protective barrier doors. It mechanically guides the powered lens as it extends to the shooting position and retracts into the compact body for storage.

The exported finder combines its front window with an Albada-style viewing lens in a separate optical path. Unlike an SLR finder, it frames without looking through the 35 mm taking lens, so close subjects can show parallax between view and recorded image.

This electronic unit groups the automatic xenon flash's front diffuser, reflector, and energy-storage capacitor. The capacitor releases stored charge in a short pulse, while the reflector and window direct and spread the resulting light toward the scene.

The exported transport combines the 35 mm cartridge position, take-up spool, and sprocket shaft. Powered advance winds exposed film and controls frame spacing, then the camera rewinds the roll when shooting is complete.

The back door closes the film chamber, and its pressure plate holds 35 mm film flat at the exposure plane. Film flatness matters because the fixed lens is calibrated to form a sharp image at one consistent distance.

The exported control unit groups the metering board, focus motor, and flexible circuit that coordinate the compact camera's programmed operation. After the release is pressed, these electronics manage autofocus, automatic exposure, shutter timing, and communication with moving lens parts.

This hardware unit combines the shutter release, mode buttons, and threaded tripod socket. The controls initiate shooting and select operating behavior, while the socket provides a mechanical mounting point for a support.

The front bezel is the structural rim around the µ[mju:]-II's fixed 35 mm lens opening. It locates the weather-seal edge and shields the front optical module when the barrier doors move.

Two joined barrier leaves form the model's automatic lens shields behind the front bezel. They move clear when the camera powers up and close over the front element when the lens retracts.

The convex front element begins the refracting path of the fixed 35 mm f/2.8 lens. As the most exposed glass surface, it gathers scene light before the remaining elements correct and focus the image onto film.

The two-stage outer barrel is the structural tube that supports the compact lens during powered extension. Its nested form lets the optical assembly reach the calibrated shooting position and then retreat behind the camera's cover.

The short-travel helical carriage moves the focusing cell along the optical axis. Under autofocus control, this guided mechanical motion changes lens-to-film spacing for subjects from the specified 0.35 m near limit to infinity.

The educational model represents the middle correction group as a cemented doublet. Its refracting surfaces share optical power and help correct aberrations within the four-element, four-group 35 mm lens specification.

This joined blade unit represents both the programmed aperture and the leaf shutter in the compact lens. The iris meters the opening while the shutter times the interval, with both actions selected automatically by the camera's exposure system.

The rear meniscus is the last modeled optical element before the 35 mm film plane. Its field-flattening role helps deliver a focused image across the rectangular frame rather than only near the optical axis.

The stepped baffle forms a matte structural throat around the rear image cone. By blocking off-axis internal reflections without clipping intended rays, it helps preserve contrast inside the compact camera body.

This fixed interface combines the chassis flange with a flexible motor tail and electrical contacts. It keeps the non-interchangeable lens module seated while carrying power and control signals across a mechanism that extends, focuses, and retracts.

The magnesium-alloy shell is the a7 III's primary structural chassis in this educational export. A rigid body keeps the lens mount, shutter, stabilized sensor, and controls in a stable relationship while protecting them from normal handling.

The faceted front armor forms the structural surround around the lens mount and the camera's shoulders. It protects the internal chassis and provides fixed exterior support without determining the E-mount's register by itself.

The deep grip is the load-bearing body projection used to hold the camera and house its battery compartment. Its shape lets the hand support the body and an 886 g FE 24–70 mm f/2.8 GM while keeping the shutter release and dials within reach.

The hinged door closes the NP-FZ100 compartment at the base of the grip. Its latch provides repeatable mechanical access to the removable battery while keeping the pack seated during operation.

The three-tab bayonet ring is the mechanical seating interface for Sony E-mount lenses. A short locking twist secures the lens at the specified 18 mm flange distance, while separate contacts carry power and data.

The 36 × 24 mm back-illuminated CMOS sensor converts the lens image into electronic signals at approximately 24.2 million effective pixels. Sony places phase-detection sites on this imaging plane, allowing the same electronic module to support capture and autofocus measurement.

The sensor rides on a floating in-body stabilization carriage represented here with its support frame and actuator coils. The a7 III corrects camera motion over five axes by shifting and rotating this platform during capture.

The dual focal-plane curtains travel across the sensor to define the mechanical exposure interval. At faster speeds they form a moving slit, while the camera can also use an electronic front-curtain mode in supported shooting conditions.

The central hump is the structural housing around the a7 III's electronic viewfinder assembly. Although its silhouette recalls an SLR prism, it encloses an electronic display and magnifying optics rather than a reflex pentaprism.

The eyepiece and magnifier enlarge the OLED finder's electronic image for the photographer's eye. These are true optical elements even though the viewed picture originates as a live sensor feed rather than light redirected by a mirror.

The tilting rear LCD presents live view, playback, menus, and touch-position input as an electronic display. Its hinge changes the viewing angle without changing the alignment of the lens, shutter, or sensor.

The mode, exposure-compensation, and command dials are the camera's principal top-plate mechanical inputs. Their rotation lets the photographer alter exposure and operating modes while keeping the camera in a shooting grip.

The Multi Interface Shoe combines a mechanical accessory rail with electrical contacts for compatible flashes, microphones, and other accessories. This exported unit is categorized electronically because those contacts extend camera communication beyond a passive mounting shoe.

The paired lugs are mechanical anchor points for attaching a camera strap. Their load is transferred into the body structure so the camera and mounted lens can be carried without stressing a cosmetic panel alone.

The mainboard houses the processing electronics that turn sensor output into autofocus data, viewfinder frames, image files, and video. The associated HDMI and USB interfaces connect those electronic systems to external displays, storage, power, and control devices.

The deep petal hood is a structural shade shaped to block oblique light without entering the 24 mm frame corners. It also surrounds the large front element, although flare control rather than impact protection is its designed optical purpose.

The threaded front ring accepts standardized 82 mm filters and accessories. It is categorized mechanically because attaching or removing a filter relies on the ring's threads rather than any optical or electronic coupling.

The oversized aspherical front element begins gathering the wide 24 mm field while supporting the zoom's constant f/2.8 maximum aperture. An aspherical surface can correct aberrations with a profile that a simple spherical element cannot provide.

The exported two-element front group represents the wide-angle correction section behind the objective. As the lens zooms, coordinated group positions change focal length while controlling distortion and maintaining focus across the frame.

The inner barrel is the structural carrier that extends as the zoom mechanism changes focal length. It supports moving optical groups against tilt and play while sliding inside the lens's main chassis.

The wide control ring gives the photographer mechanical input across the 24–70 mm focal-length range. Its rotation drives the internal cam system rather than moving every optical group by the same distance.

The cam sleeve and its three modeled guide pins translate zoom-ring rotation into guided axial movement. Shaped tracks encode the different travel required by individual optical groups throughout the zoom range.

The focus ring is a rotating mechanical control whose movement is read electronically rather than coupled directly to a focusing helicoid. Focus-by-wire lets manual input and autofocus command the lens's powered focusing system through the same control electronics.

The exported unit combines a corrective optical element, its moving carrier, and two modeled voice-coil blocks. It is categorized electronically because the actuator components position the focus group in response to autofocus or focus-ring commands.

The middle group represents the zoom-compensation optics between the focusing carrier and aperture. Its refractive power works with the moving front and rear groups to maintain image formation as focal length changes.

The aperture housing carries the electromagnetic stop actuator around the lens's optical axis. It is a mechanical carrier because it locates and moves the diaphragm assembly, even though body commands arrive electronically through the mount.

Nine joined overlapping blades visualize the FE 24–70 mm f/2.8 GM's circular aperture mechanism. Their coordinated movement changes the opening for exposure and depth of field while retaining a rounded shape when stopped down.

The rear correction stack contributes optical power and aberration control on the sensor side of the diaphragm. It directs the converging image cone toward the short-register E-mount and the a7 III's full-frame sensor.

The high-curvature rear element is the last modeled refracting surface before the mount. Its field-flattening role helps focus detail across the planar full-frame sensor rather than only near the center.

The sealed main barrel is the structural chassis surrounding the zoom's optical and mechanical core. It locates internal guides and rear components while resisting the bending and twisting loads applied to an 886 g lens.

The ultrasonic autofocus motor positions the internal focusing group from commands sent through the E-mount contacts. Sony used Direct Drive SSM in this first-generation SEL2470GM to move substantial glass quickly while keeping focus operation quiet.

The metal E-mount bayonet seats against the body's flange and locks after a short rotation. Its gasket reduces dust and moisture entry at the joint, but weather resistance does not make the mounted pair waterproof.

The exported contact block uses eight modeled pins to represent the lens's electronic connection with the camera body. Through the native E-mount interface, the real lens exchanges power and data for identification, focus, aperture, and shooting metadata.
