14mm F2.8 ED AS IF UMC Lens

Thank you for purchasing the 14mm F2.8 ED AS IF UMC lens.

We believe that you will have a special photographic experience with the 14mm F2.8 

ED AS IF UMC lens.

The 14mm F2.8 ED AS IF UMC lens mount is uniquely designed for Canon, Nikon 

(Fujifilm) F, Pentax (Samsung GX) K, Sony α (Minolta), Canon M, Sony E, Fujifilm X, 

Samsung NX, Four Thirds, and Micro Four Thirds cameras.

Hold the lens hood gently and press the lens release button on the camera. Turn the 

lens in the opposite direction of the attaching direction to detach the lens.

You can adjust the focus by turning the focusing ring when using the 14mm F2.8 ED 

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

Some cameras require special settings when using this lens.

Please refer to the following and set the camera when necessary.

 For some Canon cameras, if you set the camera mode dial to Av and set the 

  brightness by turning the aperture adjustment ring on the lens, the camera 

  automatically changes the shutter speed. Therefore you don't need to adjust the 

  shutter speed as well, which is required in M mode.

(The procedures above are for the 40D. The settings for the camera or the menu may vary based 
on the model or due to a functional upgrade. Refer to the camera instruction manual or contact the 
camera manufacturer for detailed information.)

 If the release lock is disengaged in the above way, the state of disengagement is 

  maintained even though the main switch is turned off. If you want to enable the 

  release lock function, perform the above procedure again.

 For some Samsung NX cameras, if you set the camera mode dial to A and set the 

  brightness by turning the aperture adjustment ring on the lens, the camera 

  automatically changes the shutter speed. Therefore you don't need to adjust the 

  shutter speed as well, which is required in M mode.

1)  Set the camera mode dial to M.

2)  Adjust the shutter speed to achieve the appropriate exposure for the 

 brightness.

The diaphragm of the 14mm F2.8 ED AS IF UMC Canon mount is not compatible with 

the camera.

If the brightness is set to F8 or above, you may not be able to set the correct focus 

due to a difficulty in viewing the subject through the camera viewfinder. Turn the 

aperture adjustment ring so it is fully open when attaching the lens to the camera, and 

then set the depth of field and brightness you want prior to shooting.

You can set the depth of field and brightness by turning the aperture adjustment ring 

when using the 14mm F2.8 ED AS IF UMC lens.

The F numbers can be set from 2.8 to 22.

The 14mm F2.8 ED AS IF UMC lens is a wide-angle lens and captures a vivid wide 

angle of view by minimizing image distortion. You can capture extensive panoramas, 

which is very useful for landscape shooting.

① 

To change the focus from a subject that is far away to a subject that is close,

 t

urn the focusing ring to the left (∞ to 0.28 m) and focus on the clearest subject 

  by using the indication signal on the camera, or by checking visually.

② 

To change the focus from a subject that is close to a subject that is far away,

 

turn the focusing ring to the right (0.28 m to ∞) and focus on the clearest 

   

  subject by using the indication signal on the camera, or by checking visually.

Hold the lens hood gently and align the camera mount attachment point with the 

attachment reference point or line on the lens. Push the lens into the camera and 

gently rotate the lens in the attachment direction until it makes a clicking sound.

Advantages of the 14mm F2.8 ED AS IF UMC lens

   

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 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.

Your Nikon mount has electronic contacts that allow it to communicate with Nikon AF 

cameras. These contacts enable the A, S, and P modes of the camera. When a 

subject is correctly in focus, the camera emits a beep or an indicator light comes on.

The diaphragm of the 14mm F2.8 ED AS IF UMC Sony (Minolta) mount is not 

compatible with the camera. If the brightness is set to F8 or above, you may not be 

able to set the correct focus due to a difficulty in viewing the subject through the 

camera viewfinder. Turn the aperture adjustment ring so it is fully open when 

attaching the lens to the camera, and then set the depth of field and brightness you 

want prior to shooting.

If this lens is used on some Konica Minolta (Minolta) or DYNA series cameras, the 

release lock function (misuse prevention function) of the camera must be disabled. It 

is required to disable the release lock function only on the first use, as below.

The diaphragms of the 14mm F2.8 ED AS IF UMC Canon M, Samsung NX, Sony E 

and Fujifilm X mounts are not compatible with the cameras. If the brightness is set to

Causes

Corrective Action

A lens cannot be attached to 

the camera.

A lens cannot be detached 

from the camera.

Blurry images

F

EE (blinking)

Automatic focusing does not 

work properly.

Dark or too bright pictures

The camera flash is not 

functioning.

The camera finder indication 

or the display does not 

display.

Zooming failure

This lens cannot be mounted 

on other cameras.

You want to attach our 2X or 

1.4X converter lens.

The attachment reference point on the lens 

is not aligned with the lens attachment 

reference point on the camera.

Align the attachment reference point on the 

lens with the lens attachment reference 

point on the camera.

Incorrect rotation direction for detaching the 

lens.

If you turn the lens while holding the 

camera, it may cause damage to the lens.

Press the lens release button on the 

camera, and gently turn the lens to the lens 

attaching/detaching reference points, in the 

direction as marked on the camera, and 

then pull the lens forward.

Incorrect focusing

Insufficient shutter speed or camera shake.

Turn the focusing ring while checking the 

indication or checking an object visually, set 

the focus until it becomes clear, and then 

press the shutter.

Steady the camera and take a photograph 

at a shutter speed of 1/125 secs.

The aperture adjustment ring on the lens is 

not set to the minimum aperture value.

Turn the aperture adjustment ring to set it to 

the minimum aperture value. (F22)

A manual focusing lens has trouble with 

automatic focusing.

Use the focusing ring to adjust the focus.

Inappropriate exposure

Adjust the aperture adjustment ring 

accordingly.

The non-CPU lens may not be compatible, 

depending on the camera.

See the camera manual.

This lens corresponds to the Nikon AI-P 

lens.

See the camera manual or flash manual.

This lens is not a “D-type” lens (which 

relays distance information to the camera).

This lens does not have an electric contact 

signal, so there is no communication with 

the camera through electric signals.

No problem with shooting

This lens is a single lens.

This lens is designed for its own mount.

Purchase the designated lens mount.

Our converter is designed for the T (M42 

screw) mount only. Therefore it cannot be 

used with the 16 mm F2.0 ED AS UMC CS 

lens.

Use each company's own mount converter. 

However, be aware that auto focusing is 

unavailable.

9. Safety Precautions

1. It compensates for aberrations by using a complex aspherical and glass aspherical 

    lens and, at the fully opened position, produces high resolution and high contrast at 

    the center of the lens as well as around the periphery.

2. Controls chromatic aberration optimally by using premium optical glass with high 

    refraction and extra-low dispersion.

3. Allows precision focus control by providing a soft and wide focus operation area.

4. Ultra multi coating design for optimum suppression of ghost images and vivid color 

    image reproduction.

5. Maintains an unchanged size with its inner focus design.
