How can you tell the difference between AiS and AI?

How can you tell the difference between AiS and AI?

Ai lenses have only ONE set of aperture values on them, while AiS lenses have two sets of aperture numbers….a big-sized set, and behind them and closer to the body is a smaller,secondary set of numbers called the ADP or Aperture DIrect Readout set….

How do I know if my Nikon lens is AiS?

What is the difference between AI and AI-S lenses?

1. The minimum aperture (both the main larger and smaller direct read out figures) are marked in orange i.e. F16,
2. A notch has been taken off the rear bayonet mount, above the lens locking notch. This allows certain Nikon cameras to detect if an AI-S lens is fitted or not.

How do you use a lens distance scale?

1. Focus on the nearest object you need sharp, read the distance on the lens.
2. Focus on the most distant point you need sharp, read the distance on the lens.
3. Rack the focus to the mid-point between those two points on the lens distance scale.
4. Stop down the lens aperture to the smallest number you judge might be needed.

What is the difference between depth of field and hyperfocal distance?

Wide lens apertures give shallow depth of field, while small apertures give more depth of field. And there is a way to make depth of field much simpler when you’re shooting landscape photographs. It’s called the ‘hyperfocal distance’, and it’s explained in depth at the end of this tutorial.

What does Nikon AIS mean?

The Ai-type Nikkor lens was introduced during 1977, and was the first major change to the famous Nikon F mount since it was launched in 1959. The designation is derived from the name of the method used to couple the lens with the TTL metering system of compatible Nikon cameras, which is known as Aperture Indexing (Ai).

What does AIS stand for Nikon?

In 1977 Nikon introduced the AI lens which was short for Automatic Maximum Aperture Indexing. This was a new system for coupling the lens to the camera’s exposure system. These lenses were much faster and easier to mount and release because the “AI ridge” automatically meter-couples when the lens is mounted.

WHAT IS lens distance scale?

Focusing range and distance scale These lens numbers indicate the distance at which your lens is currently focused. So at one end of the scale, you’ll find the infinity symbol, and at the other end, you’ll find the lens’s minimum focusing distance (i.e., the closest the lens can focus).

What do the numbers on the lens mean?

The first number or pair of numbers indicates the range of available focal lengths in millimeters. From this you can tell what angles of view the particular lens can handle. Lower numbers mean a wider angle. So an ordinary, basic 18-55 DSLR lens can “zoom” from medium-wide views out to the beginning of telephoto range.

Does hyperfocal distance work?

Definition 1: The hyperfocal distance is the closest distance at which a lens can be focused while keeping objects at infinity acceptably sharp. When the lens is focused at this distance, all objects at distances from half of the hyperfocal distance out to infinity will be acceptably sharp.

Is hyperfocal distance important?

Hyperfocal distance is only important to calculate when you have objects both close and far away from your lens that need to be sharp. When shooting distant landscapes without foreground elements, one does not need to worry about hyperfocal distance, since focusing is set to infinity.

Can AI-S lenses be mounted on any Nikon camera?

AI and AI-S lenses can be mounted on all Nikon cameras with an F-mount. However, lower-end cameras such as the D3xxx and D5xxx don’t have the aperture feeler so you lose light metering.

What is the highest aperture value on an AI-S lens?

> On AI-S lenses, the highest aperture value is in orange. This is true, but incomplete. The pertinent fact is that on an AI-S lens, the highest f-number on the small ADR scale at the bottom of the aperture ring is orange, whereas on AI lenses this number is white, like all of the other numbers on the ADR scale.

What is auto indexing on a Nikon camera?

In 1977, Nikon came up with a new way to couple the aperture ring to the camera’s light meter: Auto Indexing or AI. AI lenses have a ridge that catches a feeler on a ring surrounding the lens mount on the camera. (Mounting a non-AI lens may bend or break the feeler.)

What is the difference between AI and AI-S lenses?

This is true, but incomplete. The pertinent fact is that on an AI-S lens, the highest f-number on the small ADR scale at the bottom of the aperture ring is orange, whereas on AI lenses this number is white, like all of the other numbers on the ADR scale.
