This lens ring consists of a metal outer ring and a
plastic inner ring that fits the lens . barrel precisely
The inner ring allows mounting of lens, exact which
protects it from stress by providing area of greater
contact.
V2 lens ring improves its functionality by adding cut
out windows to outer and inner rings, allowing focus
distance to be read in both landscape and portrait
orientations. It also allows access of AF/MF switch.

Roll angle of camera can be set relative to the AF/MF switch on lens. More
accurate value can be obtained by extending the reference mark on the lens
using a piece of tape or label. It can be read in 30° intervals by aligning
notches at the back of outer ring to AF/MF switch or the added mark.

Installing Lens Ring to Lens
Tips and Tricks
Using Different Roll Angle in Different Situations
Loosen the knob on outer ring until the
edge of opening is flush with lens ring
plate. Don’t loosen further. It will only
make installation more difficult and can
potentially damage the thread if knob
is completely unscrewed. See Page 2
for trouble shooting.
Squeeze to take out the inne r ring.
Check label on inner ring to confirm
wi th le ns i n use a nd di rec ti on of
mounting. The arrow should point to
the front of lens.
Align window on the inner ring to the
refe ren ce mark of t he foc us scale.
Insert the lens. Stretch the ring when
necessary. Move it to a position where
it fits snugly. Push it against the anchor
point on lens to ensure exact mounting
and consistent NPP setting.
Align base of outer ring to opening of
inner ring. Insert outer ring from the
back of lens. Loosen lens ring knob
slightly if necessary. Rotate and slide
un til p osit ion ed on to inn er rin g.
Tighten fully. Mount lens to camera.
We suggest fixing the inner ring with a
piece of tape about 40mm (1.5”) long.
Stretch the tape so that the ring will
grasp the lens firmly. This eases installation of outer ring and prevents movement of inner ring when outer ring is
rotated. Cut any tape that goes beyond
trimmed area of inner ring. This step
can be skipped if users do not plan to
rotate outer ring.
Mount lens ring to quick release clamp
of pano head in use. Rotate to align
windows of outer and inner rings with
camera in landscape or portrait orientation. Slide the lens ring plate to NPP
setting and tighten the clamp fully.
A unique feature of the lens ring is its ability to roll
the camera into different angles quickly. Experts in
the field use different roll angles with crop sensor
cameras in different situations. A roll angle of about
60° (sensor diagonal aligned vertically) can be used
to diagonal angle of view over take advantage of
horizontal and vertical to increase overlap or reduce
number of images to be taken. This is important in
multi-camera rig for capturing instantaneous action
pan oramas o r pan oramic v ide os, where fewe r
cameras equal substantial cost saving. A camera can
also be rotated to landscape orientation temporarily
to take extra shots to capture large moving objects
such as waves, trains, busy traffic and various kinds
of racing. The larger horizontal angle of view help to
freeze the scene and reduce stitch issue due to
movement across multiple image shots. The area
near nadir and zenith usually contains static objects
and is easy to stitch.
The lens cover consists of a cap and a lens hood. The cap and hood must be
removed in order to get enough angle of view for taking panos with 4 shots
around.

Outer Ring Knob Completely Unscrewed
The outer ring knob should not be unscrewed completely. If unscrewed completely, the
thread inside the socket can become damaged if the screw is canted or skewed while
attempting to re-tighten. Should the knob completely unscrews, ensure the knob screw is
parallel to the lens ring plate again, then tighten the knob slowly. If a strong resistance is
felt, loosen it and try again. DO NOT FORCE THREAD THE SCREW. If you are unable to tighten
the knob, please contact customer support for assistance.
