Nikon Z7 Mirrorless Camera with 24-70mm Lens (Refurbished)

Introducing the Z mount, Nikon's full-frame mirrorless system promises to deliver class-leading image quality and optics in a compact form factor. The Z mount itself makes much of this possible with a 17% larger inner diameter than the F mount, enabling the use of more advanced optics and lens designs, including ultra-fast f/0.95 options. For minimizing camera and lens size, the Z mount features a 65% shorter flange distance, measuring just 16mm, which allows for dramatically slimmed down body designs. The larger mount also supports faster and larger-volume communications between the body and lens to improve overall performance throughout the system.

A 45.7MP BSI CMOS sensor is used for high-resolution shooting, impressive low-light quality, and fast readout speeds to benefit continuous shooting, movies, and time-lapse recording. The back-illuminated design of the sensor affords noticeably cleaner high-sensitivity output for reduced noise when working at high ISO values, up to a native ISO 25600, as well as vivid and smooth quality at sensitivities as low as ISO 64. The sensor's design also omits the conventional optical low-pass filter in order to achieve the greatest sharpness and resolution from the sensor. Benefitting the sensor is the apt EXPEED 6 image processor, which affords a wealth of speed throughout the camera system, including the ability to shoot continuously at 9 fps in raw.

Utilizing the sensor and processor attributes for more than just still imagery, the Z7 is also a more-than-capable multimedia camera. Video recording is possible at UHD 4K (3840 x 2160) using either the full-frame area or a DX crop area in 30p, 25p, or 24p frame rates. Full HD 1080p video recording is also supported at up to 120p for slow motion playback, and video files can be saved to the in-camera memory cards or as an uncompressed file to an optional external recorder via HDMI out.

Advanced video functionalities have been added with the Z7. This includes the N-Log gamma for capturing flat-looking footage that maximizes dynamic range. Other additions are the ability to output high-quality 10-bit data over HDMI and an Electronic VR function for smooth handheld shooting. Focus Peaking can be used to benefit manual focus control and a Zebra Stripes option is also available to help detect over-exposed areas within the frame. Audio recording can be handled using the built-in stereo microphone or an optional external mic can be added via the 3.5mm stereo jack for greater control over quality, and live monitoring is possible via the headphone jack.

Further complementing video capabilities, the Z7 is eligible for an optional ProRes RAW upgrade, enabling the camera to output ProRes RAW footage to a compatible Atomos external recorder. This upgrade provides greater color grading flexibility with the ProRes codec along with the ability to output uncompressed 12-bit raw footage over HDMI. This upgrade requires sending the camera to Nikon's Service Department for installation.

The Z7 also blends both still and video capabilities with the ability to produce 8K time-lapses using the Interval Timer Mode or in-camera 4K time-lapse movies, with the ability to record up to 9999 exposures for either method. This system also makes use of a silent interval timer, which produces no shutter noise, does not contribute to wear on the shutter mechanism, and is energy efficient to maximize battery life.

Located on the sensor is an array of 493 phase-detect autofocus points covering 90% of the image area both vertically and horizontally. This provides fast and accurate focusing for both stills and video and with a wide coverage area, subject tracking will work out to near the edges of the frame. Hybrid AF is available for video, which will automatically switch between phase- and contrast-detect systems to provide smooth focus during shooting. Additionally, the latest NIKKOR Z lenses are optimized for silent operation.

Included with the camera body is the standard zoom NIKKOR Z 24-70mm f/4 S lens, which covers a wide-angle to portrait-length range and features a constant f/4 maximum aperture. The optical design incorporates one aspherical element as well as a unique aspherical extra-low dispersion element; both of which help to greatly reduce a variety of aberrations and distortion for high sharpness and accurate color rendering. A Nano Crystal Coating is also used to control flare and ghosting for increased contrast in strong lighting conditions. Suiting both photo and video applications, a stepping AF motor is also featured for smooth, near-silent autofocus performance.
