Lever Lock Type E-Mount system
Sony's new mount system securely locks E-Mount lenses to the camera body and enables the use of larger, heavier lenses without need for additional support.
This breakthrough is based on a clever combination of advanced material
science and ingenious engineering. The Lever-Lock Type E-Mount securely holds E-Mount lenses and adapters to the camera body. In fact, it can hold
unsupported: Long, cine and zoom lenses of similar weight to unsupported PL-Mount lenses on the F55 (under static and dynamic loading).
the FS7 II Lever Lock Type E-Mount is similar to operating the PL-Mount common to cinema cameras.
Place the E-Mount lens in the Lever Lock Type E-Mount
opening and then, with your free hand, rotate the locking ring in a counterclockwise direction. This securely clamps the E-Mount lens in the mount.
When the ring comes to a stop, a secondary latch automatically locks the ring in place to prevent unintentional disengagement. To disconnect the lens, switch off
the secondary latch, then rotate the locking ring in the clockwise direction to release the lens.
All the usual benefits of the E-Mount are retained.
Electronic Variable ND
Sony's unique new Electronic Variable ND technology, first introduced in the FS5, provides "run and gun"
filmmakers with a whole new means to seamlessly adjust exposure while shooting.
Variable ND frees the lens iris from the traditional job of exposure control. With
Variable ND, the lens iris can be dedicated instead to the important job of setting depth-of-field. In documentary field work, bright exteriors and dim
interiors no longer need automatically result in distracting variations in depth-of-field.
Variable ND also permits any lens to be used
consistently at its "sweet spot" within its best f-stop or T-stop range (peak optical performance for that particular lens). In so doing, Variable ND avoids
the image degradation and softening that typically accompanies opening or closing the lens iris too much.
The FS7 II offers three different
Variable ND operation modes: Preset Variable ND, Manual Variable ND and Auto Variable ND. Large, easily accessible switches on the front side of the camera
permit quick switching between these modes with the camera on the operator's shoulder.
Preset Variable ND
The ND turret knob
enables four presets for ND attenuation. The first preset is "clear," in other words, no ND. That leaves three preset settings, which are user-selectable in
1/3 stop steps within the camera's 2 to 7 stop range.
For example, each of the three user-selectable ND presets might be set to a desired ND density for each of
three particular scenes, which, in combination with iris settings, could give each scene a particular look with regard to depth-of-field.
Manual Variable ND
This mode is ideal for "run and gun shooting." The operator can manually adjust exposure by turning either a knurled wheel near
the front of the camera or an index-finger wheel on the SmartGrip. In either case, the result is a smooth, seamless adjustment of exposure within a 2 to 7
stop attenuation range. Both control wheels can be user-assigned to control ND density--or one of them can be reassigned to adjust audio level or lens iris.
A smarter SmartGrip arm
The length of the FS7 II's SmartGrip can be changed without any tools. The new design uses knobs contoured
to facilitate locking and loosening by hand, even when wearing gloves. Furthermore, the new design enables relocating the SmartGrip to a new position,
closer to the camera body. This makes it easier to hold the FS7 II against the chest or underarm to permit shooting more comfortably, from more angles.
Media easier to eject
XQD cards now project twice as much from their slots in order to facilitate card changeover while wearing gloves
