The Nikon Z-mount system is a mirrorless camera lens mount developed by Nikon for its full-frame mirrorless cameras, starting with the Z series. Introduced in 2018, the Z-mount system signifies Nikon’s transition from DSLR to mirrorless technology while maintaining compatibility with its extensive F-mount lens lineup through adapters.

The Z-mount has a flange focal distance of 16mm and a throat diameter of 55mm.

Strengths:

• Large throat diameter enables the development of high-quality lenses with fast apertures and optimal optical performance
• Short flange focal distance allows for a more compact camera and lens system
• Compatibility with Nikon’s F-mount lenses via the FTZ adapter, providing access to a vast range of existing lenses
• Expanding native Z lens lineup catering to various user needs and budgets
• Integration with Nikon’s established ecosystem, making it easier for existing Nikon users to transition to the Z system
• Nikon’s autofocus and metering technologies provide fast and accurate focusing capabilities with Z lenses

Weaknesses:

• Limited native Z lens lineup compared to more established systems, although the lineup is continually expanding
• Limited third-party lens options, although this is gradually changing as more manufacturers develop Z-mount lenses
• Adapting F-mount lenses can lead to slightly reduced performance compared to native Z lenses, particularly in terms of autofocus speed and accuracy
• The cost of entry for some Z lenses can be high
