Samyang AF 50mm F1.4 FE Instruction Manual

Thank you for purchasing this Samyang Optics product.

The Samyang AF 50mm F1.4 FE lens is a high performance single vision
lens designed exclusively for the E-mount of SONY αinterchangeable­lens cameras. (This lens cannot be used with an A-mount camera.)

※ FE refers to the full frame E-mount.

󳢯The lens is designed exclusively for mirror-less cameras, where the

distance between the DSLR contrast lens and the image sensor is
close, and affords the user excellent performance and results.

󳢯This lens allows the user to shoot optimal quality picture and video in

response with the 35mm Full Frame image sensor.

󳢯This large-caliber lens gathers as much light as possible and provides

the best image quality among equivalent models.

󳢯It minimizes various aberrations, and creates a clear image by using

three high precision aspherical lenses.

󳢯The fast and accurate AF (autofocus) function ensures excellent optical

performance.

󳢯 Its size, comfortable for holding and shooting, provides a firm grip

feeling, enhancing the stability for shooting.

󳢯Its simple but refined design as well as metallic material ensures a

luxurious look and excellent durability.

󳢯This product is designed in the form of an inner focus lens, meaning the

lens does not come out or rotate according to the focal distance, and is
therefore free from dust and convenient for using a polarizing filter.

󳢯Please read this instruction manual and familiarize yourself with the

functions of the lens, the operating method, and cautions for handling
the product correctly prior to use. Also, refer to the instruction manual of
the camera you are using with the lens.

󳢯The supported functions of this product may vary according to the

camera model.

In order to maintain the user's safety and prevent damage to the product,
fully familiarize yourself with the following items in order to use the product
correctly.
󳢯It is dangerous to look at the sun through the lens directly. It may

seriously impair your vision.

󳢯Be careful not to apply an impact when attaching the lens. The lens is a

precision optical product, so dropping or applying an excessive impact
to the lens may cause product failure.

󳢯In order to use the lens safely, attach or detach the lens while the

camera is turned off.

󳢯Be careful not to touch or contaminate the contact point of the mount. If

an electronic signal is not transmitted between the camera and the lens
smoothly, a malfunction may occur.

󳢯Do not wet the lens or touch the lens with a wet hand when using the

lens near water. Doing so may result in fire or electric shock.

󳢯It is recommended to use a strong tripod. If a weak tripod is used, the

tripod may fall down, damaging the camera and the lens.

󳢯Do not store the lens without the lens cap in a location with direct

sunlight, such as inside a vehicle. Direct sunlight passing through the
lens may be concentrated, causing a fire.

󳢯If the lens is placed in a hot location, damage or distortion may occur,

and a problem in its performance may result.

󳢯Store the lens in a dry and well-ventilated location. Avoid direct sunlight

and do not store the lens with naphthalene or moth balls.

󳢯Avoid using the lens in a location with drastic temperature changes. In

particular, if you move a lens that has been chilled in a cold location to a
warm location, moisture in the air may be concentrated outside or inside
the lens, causing a failure or mold production. In such a case, keep the
lens in a plastic bag or an exclusive camera bag and take it out when
the temperature of the lens becomes similar to the peripheral
temperature.

󳢯Keep the lens out of the reach of children. Failure to do so may cause

an accident or personal injury.

󳢯If the lens surface gets dirty, dust it off using a lens blower or a brush

and wipe it with a soft and clean cloth (cleaning tissue, cotton cloth,
etc.).

󳢯When dusting or cleaning the lens, do not use an organic solvent such

as thinner, alcohol, or benzene.

󳢯When cleaning the lens, put a small amount of ethanol or lens cleaner

on a soft and clean cloth or a cleaning paper and wipe the lens by
circling outwards from its center.

Name of each part

󳢯Attaching the lens

- Remove the front cap and the rear cap of the lens.

- Align the mount index (white dot) indicated on the lens to the lens
mount index (white dot) indicated on the camera mount, and rotate the
lens clockwise until a clicking sound occurs.

󳢯Detaching the lens

- With the camera lens detaching button pressed, detach the lens by
rotating it counterclockwise until the lens stops.

󳢯There are five focus methods for SONY αinterchangeable-lens

cameras. (

※ This may vary according to the camera model.)

- AF-S (Single shooting AF): The focus is adjusted automatically in the
camera.

- AF-A (Automatic AF): The camera switches to single shooting AF or
continuous AF mode automatically according to the movement of a
subject.

- AF-C (Continuous AF): The focus is adjusted continuously in the
camera.

- DMF (Direct manual focus): Manual fine adjustment is available after
automatic focusing.

- MF (Manual focus): The focus is adjusted manually.

󳢯For detailed content regarding the focus mode setting, refer to the

instruction manual of the camera.

󳢯The hood blocks unnecessary light and protects the front surface of the

lens from rain, snow or dust.

- Align the mount position index indicated on the hood with the hood
index (white) indicated on the lens, rotate the hood clockwise until a
clicking sound occurs and the hood is fixed.

- You can store the hood by mounting it on the lens in the opposite
direction.

※ Caution: If the hood is not mounted correctly, vignetting may occur.

(Vignetting: A reduction of an image's brightness at the periphery
compared to the image center occurring when the angle of the lens’
view is covered)

󳢯A filter can be mounted on the filter mounting screw at the front of the

lens.

- Only one filter can be mounted.

※ If two or more filters are mounted at the same time, vignetting may

occur.

- Check if the filter size is compatible with the lens (refer to “Product
specifications”), and then mount it at the front of the lens.
