We believe that you will have a special photographic experience with the 50 mm

F1.4 AS UMC lens.

Advantages of 50 mm F1.4 AS UMC

1. 50 mm F1.4 AS UMC full frame image size.

2. It compensates for aberrations by using a glass aspherical lens and hybrid

aspherical lens and, at the fully opened position, produces a high resolution

and a high contrast at the center of the lens as well as around the periphery.

3. The flower-shaped hood and UMC (Ultra Multi Coating) design suppresses

flaring and ghost images.

4. Robust durability with a high strength aluminum body.

This product is designed with its own mount so you can easily take photographs

by mounting the lens directly onto the camera, without installing an additional

adaptor.

※ Read this instruction manual carefully to familiarize yourself with your lens for

correct use.

※ Please read the Safety Precautions at the back of this instruction manual prior

to use.

The 50 mm F1.4 AS UMC lens mount is uniquely designed for Nikon (Fujifilm) F,

Fuji X, Pentax (Samsung GX) K, Sony (Minolta), Canon EOS, Canon M, Four

Thirds, Micro four thirds, Sony E, Samsung NX compatible cameras.

You can adjust the focus by turning the focusing ring when using the 50 mm F1.4

AS UMC lens, as it is a Manual Focus (MF) adjustment lens.

ex)

1.4 and 2 are 1 stop (1 EV) away from each other.

Set a brightness between 1.4 and 2,

which is 0.5 of a stop (0.5 EV) between the two

The hood has a bayonet system which guarantees speedy, efficient, safe and precise

installation, and enables you to enjoy shooting that is free from ghosting or flaring.

Align the attachment reference point on the hood with the reference

point for a hood on the lens, push the hood onto the lens and turn the

hood to the right until it makes a clicking sound.

The 50 mm F1.4 AS UMC lens supports a maximum brightness of 1.4.If you take a

photo in an outdoor place exposed to sunlight, you may not get a clear image

because the subject is too bright.Since the depth of focus becomes too shallow at

brightness 1.4, if the subject is not focused correctly you may get an unclear image.

Therefore, to get a clear image, focus the subject correctly and then take the photo.

Some cameras require special settings when using this lens.Please refer to the

following and set the camera when necessary.
