Nikon 1-mount

Nikon 1-mount is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Nikon 1-mount rather than just read about it. In short: The Nikon 1-mount is a type of interchangeable lens mount developed by Nikon for its Nikon CX format mirrorless interchangeable-lens cameras. The 1-mount was first introduced on the Nikon 1 series in 2011, and features a three-lug bayonet mount with a 40 mm throat and a flange to focal plane distance of 17 mm.

Key takeaways

Nikon 1-mount belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Nikon 1-mount to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Nikon 1-mount from memory before moving on to harder problems.

Reference excerpt

The Nikon 1-mount is a type of interchangeable lens mount developed by Nikon for its Nikon CX format mirrorless interchangeable-lens cameras. The 1-mount was first introduced on the Nikon 1 series in 2011, and features a three-lug bayonet mount with a 40 mm throat and a flange to focal plane distance of 17 mm.

Cameras

The Nikon 1 series of mirrorless interchangeable lens cameras was originally announced on 21 September 2011 with two cameras, the Nikon 1 V1 and the Nikon 1 J1. It grew over the following seven years to have a total of 11 cameras. Nikon discontinued the series in July 2018, when the Nikon Z-mount was introduced.

Lenses

Zoom lenses

Power zoom lenses These lenses have an in-lens motor to operate the focal length control, aimed at making smooth zooms during videography.

Prime lenses

All-weather lens Lenses are optically identical to their non-sealed counterparts and use the same bayonet, but have an extended flange to ensure a watertight seal with the Nikon 1 AW1 body.

Nikon 1-mount adapter to use F-mount lenses Nikon SLR cameras, both film and digital, have used the Nikon F-mount with its 44 mm throat iameter and 46.5 mm flange since 1959, while the 1-mount has a 40 mm throat diameter and a 17 mm flange distance. The FT-1 lens adapter allows many F-mount lenses to be used on 1-mount cameras. The FT-1 adds 29.5 mm to the length of the attached lens, which is the difference in flange distance between the Nikon F-mount (46.5 mm) and the 1-mount (17 mm). When used with the FT-1, F-mount lenses have a 2.7x crop factor, e.g., a 300mm lens acts like an 800mm lens. An adapter is attached to a powered-off camera in the same manner as a lens. Once it is attached, the F-mount lens can then be attached to the adapter. The mount adapter provided by Nikon to support F-mount lenses on their 1-mount mirrorless cameras is:

Nikon FT-1: The FT-1 supports the use of all F-mount lenses especially with integrated autofocus motor. The FT-1 adapter mounts and meters with all AI-P, AF, AF-S, D and G lenses and compatibles providing autofocus with all lenses with integrated autofocus motor. It further mounts Pre-AI, AI, AI-S and E lenses without metering as well as lenses which jut out the F-mount. Although not recommended, it can be used with teleconverters for extreme telephotos.

Third party lens

Future lenses At the Nikon 1 launch in October 2011, Nikon showcased seven prototype lenses. As of October 2012, five of those lenses had been produced. Due to its introduction of the Nikon Z-mount, Nikon discontinued the Nikon 1 line in 2018, including cancelling any future lens releases.

Worked examples

Example 1 — a first encounter with Nikon 1-mount

Start with the simplest possible case. Write down what Nikon 1-mount claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Nikon 1-mount before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Nikon 1-mount ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Nikon 1-mount

In research: Nikon 1-mount appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Nikon 1-mount in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Nikon 1-mount is common in secondary-school and first-year university syllabi. It links to neighbouring topics Lens mounts, Nikon 1-mount cameras, Nikon 1-mount lenses, so understanding it makes those chapters shorter.
In everyday life: Look for Nikon 1-mount outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
