T-S24mm F3.5 ED AS UMC
Instruction Manual
Thank you for purchasing T-S24mm F3.5 ED AS UMC lens.
We believe that this new T-S24mm F3.5 ED AS UMC lens for video recording will give
you a special photographic experience.
The T-S24mm F3.5 ED AS UMC lens is a retrofocus type lens which corrects and
emphasizes the perspective, and also adjusts the depth of field.
This lens completes an optical system based on superior optical technologies, and
maintains excellent resolution both at the center and around the periphery of the lens
by adopting a high performance Glass Molding ASP lens and a UMC (Ultra Multi
Coating).
The tilt shift unit controls the depth of field to the subject and the area for shooting. This
lens compensates for image distortion and allows you to capture various images that
you were never able to do with the existing lenses.
Advantages of the T-S24mm F3.5 ED AS UMC
1. Image size of 35mm full frame.
2. It compensates for optical aberrations using a high performance aspherical lens.
3. In the fully open position, it produces a high resolution and high contrast at the
center of the lens as well as around the periphery.
4. The UMC (Ultra Multi Coating) design suppresses flare and ghost images.
Since the T-S24mm F3.5 ED AS UMC lens is designed for a designated mount, you
can easily take photographs without installing an additional adaptor, by mounting the
lens directly onto the camera.
Please read this instruction manual carefully and use it accordingly.
※ Please read the safety precautions at the back of this instruction manual prior to
use.
Please read this instruction manual prior to use.

2. Attaching to and Detaching from the Camera
When attaching or detaching the T-S24mm F3.5 ED AS UMC lens, make sure that the
tilt scale and the shift scale are positioned at ‘0’ and locked.
Failure to do so will make it difficult to attach a lens to the camera since the tilt or shift
part moves.
Attaching
Hold the tilt area of the lens gently, align the lens mounting reference point or line with
the lens ring mount of the camera, push the lens into the camera and turn the lens
softly in the attaching direction until it makes a clicking sound.
Detaching
Hold the tilt area of the lens gently, press the lens release button on the camera, turn
the lens in the opposite direction to that for attaching, and pull it out.
3. Focus Adjustment
You can set the focus for a subject by turning the focusing ring when using the T-S24
mm F3.5 ED AS UMC lens, as it is a Manual Focus (MF) adjustment lens.
When using the tilt/shift function, you cannot check if the focus is correct using the
distance scale of the lens.
If you have a camera which allows you to view images through the viewfinder or to
capture a live view, check the focus while looking at an enlarged image. If you change
the tilt and shift values after setting the focus, the subject will be out of focus.
Nikon Mount
① When focusing on a subject from a far distance,
turn the focus ring to the left (∞ to 0.2) and focus on the clearest subject by using
the indication signal on the camera or by checking visually.
② When focusing on a subject from a near distance,
turn the focus ring to the right (0.2 to ∞) and focus on the clearest subject by using
the indication signal on the camera or by checking visually.
Sony α / Canon Mount
① When focusing on a subject from a far distance,
turn the focus ring to the right (0.2 to ∞) and focus on the clearest subject by using
the indication signal on the camera or by checking visually.
② When focusing on a subject from a near distance,
turn the focus ring to the left (∞ to 0.2) and focus on the clearest subject by using
the indication signal on the camera or by checking visually.
4. Brightness Control
You can set the desired brightness by turning the aperture ring when using the
T-S24mm F3.5 ED AS UMC lens. You can set the F NO from 3.5 to 22.
When using the tilt/shift function, vignetting or slight color change may occur. Vignetting is a phenomenon where the corners of the image darkens. To reduce this, close the
aperture or compensate the exposure prior to shooting.
Experience is required to determine the correct exposure using the tilt/shift function.
It is recommended to test shoot until you feel comfortable with the exposure.
5. Tilt&Shift control
The tilt/shift unit controls the depth of field to the subject and the area for shooting This
lens compensates for image distortion and allows you to capture various images that
you were never able to do with general lenses.
5-1. Tilt control
The T-S24mm F3.5 ED AS UMC lens allows you to express the depth of field to the
subject in various ways using the tilt unit. It is recommended to use a tripod for proper
shooting.
Make sure to differentiate the knob for tilting. The tilting knob is black and the locking
knob is grey. Use the black knob to adjust the tilting and rotate the grey knob in L
direction to hold it in place.
※ CAUTION
When you use the tilt function, make sure that you do not touch the sensitive
areas of the tilt unit.
Do not turn the knobs with excessive force. Doing so may damage the knobs.
5-2. Shift control
The T-S24mm F3.5 ED AS UMC lens allows you to correct distortion of the subject
using the shift unit. It is recommended to use a tripod for proper shooting.
Make sure to differentiate the knob for shifting.
The shifting knob is black and the locking knob is grey. Use the black knob to adjust the
shifting and rotate the grey knob in L direction to hold it in place.
If the amount of shift is large, the lighting may be different at the top or bottom of the
image or on the left or right of the image. Therefore it is recommended to shoot by
reducing the aperture value.
5-3. Lens rotation movement
The tilt/shift direction can be changed by turning the tilt/shift unit.
If you pull the mount rotation lever and the tilt rotation lever when the lens is mounted
on the camera, you can rotate the tilt/shift unit.
90° rotation is available for the mount and tilt units.
The lens is half secured at every 30 degrees and fully secured at 90 degrees.
Please note that there is a danger of pinching your finger in the locking lever when you
rotate the tilt/shift unit at a high speed.
When rotation starts you can remove your hand from the rotation unlocking knob, since
the rotation will continue.
If the lens is secured at 90 degrees, press the knob and rotate it.
6. Cameras that Need Special Settings
Some cameras require special settings when using this lens.
Canon
The diaphragm of the T-S24mm F3.5 ED AS UMC Canon mount is not compatible with
the camera. If the brightness value is set to above F8, the user may have difficulty in
setting the correct focus by viewing a subject through the camera viewfinder. Therefore
focus on a subject with a fully open aperture when attaching this lens to the camera,
and then set the depth of field and brightness you want to express prior to taking the
photo.
1) Set the camera mode dial to M.
2) Adjust the shutter speed to achieve the appropriate exposure for the brightness.
※ The shutter speed of some Canon cameras changes automatically if the shooting
mode dial is set to Av and the brightness is set by turning the aperture ring.
Therefore the shutter speed is not required to be set additionally as with the M
mode.
(The above procedure applies to 40D. Settings for the camera or the menu may
change, depending on the model or due to a menu upgrade. Therefore refer to the
camera manual or contact the camera manufacturer for detailed information.)

The diaphragm of the T-S24mm F3.5 ED AS UMC Nikon mount is not compatible with
the camera.
If the brightness value is set to above F8, the user may have difficulty in setting the
correct focus by viewing a subject through the camera viewfinder. Therefore focus on
a subject with a fully open aperture when attaching this lens to the camera, and then
set the depth of field and brightness you want to express prior to taking the photo.
(The above procedure applies to the D8000. The settings for the camera or the menu
may change depending on the model or due to a menu upgrade. Therefore refer to the
camera manual or contact the camera manufacturer for detailed information.)
