Attaching and removing
The HTS 1.5 is attached to the camera in the same manner as
mounting a lens, matching the alignment index 9 with the index
on the camera body. The lens is mounted onto the adapter in
the same manner, matching the alignment index 1. The lens and
adapter can be mounted singly or combined. Removal is either
singly or combined using the lens lock (6) on the adapter and the
lens lock on the camera body in the conventional manner.
Attaching the HTS 1.5 displays a new screen on the camera
grip to indicate the HTS button. When pressed, it will bring up
the HTS screen on the display showing the movements' data,
namely, shift in mm, tilt and rotation in degrees.

HTS 1.5 settings
Shift and tilt movements have click stops for zero settings and
are lockable. Rotation has clickstops for each 15º but can be
set at any angle up to 90º clockwise or 90º counter-clockwise.
The shift and tilt adjustment knobs are released by rotating the

Inside the camera
The enlarged image circle
is projected onto the sen-
sor (grey rectangle).
Part of the image lies
outside the sensor.
(In reality the projected
image would be inverted)
The top of the blue object
is now projected onto the
sensor but the verticals
have converged.
After returning the camera
to the level position and
shifting the lens upwards,
the projected inverted
image moves upwards, al-
lowing the top part of the
subject onto the sensor.
The verticals remain paral-
lel in the result.
Getting Started
locks (2 and 4) in a counter-clockwise direction. The adjustment
knobs are then rotated in either direction until the desired posi-
tion is achieved and then secured in place by rotating the locks
in a clockwise direction.
The amount of shift and tilt adjustment can be read off the
scales (7 and 10) by the indicators or the camera grip display.
Note that settings made according to the clickstops or the
scales are very close but approximate. For example, when tilt
has been zeroed by the clickstop, the reading on the grip may
be displayed as 0.4°. Please note therefore:

For critical use, always check the settings on the camera grip display.
All movements data is automatically stored with each individual
file and can be later viewed in Phocus.
It is good practice to ensure that both shift and tilt have been
zeroed before you start work. There is no indication in the view-
finder display regarding the amount of movement set and it is
not always obvious just by looking at the image in the viewfind-
er. Also, check the orientation of the adapter, making sure it is
capable of tilting or shifting the lens in the desired directions. In
the case of architectural/documentary photography or similar it
would also be advisable to level the camera in all planes before
work begins.

Remember when using shift that the equipment in use will have an effect on
results. Smaller sensor models will allow more movement and film magazines
(because the film area is greater) will allow less less movement to exploit
before vignetting becomes noticeable.

A 90° clockwise rotation is not possible if a GIL (GPS accessory) unit is attached.
Camera settings
There is no need to make any specific camera settings. You
may, however, wish to make a new user profile for the sake of
convenience. For example, you might want to set the buttons at
the rear of the grip to Stop Down and Mirror Up for easier thumb
access (see following section for details). Autofocus and focus
aid are automatically inactivated.

The HTS 1.5 is very simple to use. The
high level of integration within the system
makes it almost seamless in operation.

Lens settings
Focus is manually controlled while shutter and aperture settings
are controlled in the conventional manner from the camera (or
Phocus, if tethered).
Exposure settings
For optimum accuracy, exposure should be measured with shift
and tilt set at 0mm and 0°. You will note that when movements
are more than 1mm or 1°, the exposure information is no longer
visible in the viewfinder. This information immediately returns,
however, when the movements are zeroed again.
The preferred method is therefore Manual or using Auto and
then locking the reading. Shift and tilt changes can be made
without altering the exposure settings again as the H3D II takes
such movements into account. If, however, lighting is altered,
then for accurate exposure readings, movements will have to be
set back to zero and a new reading taken.
Particular attention to consistent exposure settings should be
shown when using shift to 'stitch' shots, in order to avoid post–
production problems.
Technically, any alteration of sensor to lens distance demands
a corresponding exposure compensation (as takes place during
tilting) but the camera assesses the data from the HTS 1.5 and
makes the necessary compensation automatically.
Mount extender
The mount extender is attached to the camera foot by inserting
the positioning pin on the extender into the recess in the quick
coupling plate on the camera and rotating the retaining screw
clockwise into place. The mount extender creates clearance
from the tripod/stand head to allow for free rotation of the unit.
Storage and transportation
It is recommended that you store the HTS with zero movements
in the supplied case. Avoid leaving the HTS for long periods with
extreme movement settings, particularly in very hot conditions,
for example, in a closed car in the sun. Occasionally check the
optics for dust or marks, treating the glass surfaces with the
customary precautions.
