Safety
•Do not use around flammable gas. All electrical equipment can
generate sparks that can ignite flammable gas.
•The head has powerful motors that can pinch, so take care not to get
your hands trapped in the head or cabling.
•Keep the equipment dry. The system has not been made
weatherproof. Do not use with wet hands.
•Keep cables tidy. Use cable ties to keep them out of harm’s way. If
you have a head with slip rings then make use of them; avoid
running any cables between the base and the rotating head or
camera.
Overview
Thank you for using the SFH-50 robotic camera head from Mark Roberts
Motion Control (MRMC). The SFH-50 head is designed for reliable
day-in, day-out use in professional studio environments. The versatility of
the SFH-50 makes it suitable for live action, stills, and time-lapse
applications.
You can connect your SFH-50 to any MRMC controller, such as a PC
running Flair Motion Control Software or one of the MSA-based
controllers such the Large Flat Panel (LFP), MSA-20 Handwheels,
Joystick Controller, or Mini MSA.

Setting up the hardware
1. Mount the SFH-50 head onto your choice of support, such as a
heavy-duty tripod or metal plate. The head can be over-slung
(sitting on a tripod or platform) or under-slung (hanging from its
mount).
Further details about mounting specifications are described in
Appendix 3 Specifications.

SFH-50 with Roll Ring:
Hint
If your SFH-50 has a Roll Ring and you use under-slung
mounting, move the camera platform to the bottom
(lowermost) position by manually rotating the Roll Ring 180°.
Do not move the camera platform to the bottom by inverting
the Tilt, as doing this will twist the Roll motor cable that goes
through the Tilt axle.

2. Adjust the height of the camera platform relative to the head, so that
the camera lens will be at the same height as the Tilt axis (and
centred in the optional Roll Ring) when the camera is mounted later.
Do not adjust the platform height when a camera is mounted.
To adjust the height on an SFH-50 with a Support Arm, loosen the
five retaining bolts that hold the camera platform in place (one on
the Support Arm, then four on the main platform arm), turn the
two height adjustment bolts to achieve the platform height you
want, then re-tighten the five retaining bolts.

To adjust the height on an SFH-50 with a Roll Ring, loosen the six
retaining bolts that hold the camera platform in place (four in the
rear, two in the front), turn the height adjustment bolt to achieve the
platform height you want, then re-tighten the six retaining bolts.

3. If you are using external Lens Control Motors (LCMs) mounted on
the head, bolt the mounting rods onto the head, then mount the
LCMs onto the rods in approximately the correct position. You can
fine-tune the position later.
