Thank you for purchasing Xit 404's Canon 20mm Focus Ring to use with
our Manta Gears. On the back is our warranty information to help you
prolong the life of this product.
This product is in our Manta Line. The advantage of the Manta Line of
Rings and Gears is that the parts are interchangeable. For example the
Manta Gear fits on all Manta Focus/Zoom Rings as well as our
Manta Teleconverter Extension Rings. This allows you to purchase one
gear that mates with a variety of lenses.
Assembling the Focus Ring to your Manta Gear
If you are manual focusing make sure your lens switch is in manual mode.
Look at the drawing to the left and note which end of the lens the Focus
Ring slides onto. Then follow the instructions below.
1. Slide the Focus Ring onto your lens from the back until it stops.
2. Slide the Manta Gear on from the back of the lens. Align the white
dot on the Manta Gear with the unpainted red dot on the Focus Ring.
Then press the two parts together. Once the the two parts are fully
mated, while holding the Focus Ring with one hand, and pressing
the red Manta Gear latch with thumb, twist the Gear until the white
dots line up (note: the locked icon). The Manta Gear is now locked
onto the Focus Ring.
Disassembling the Focus Ring
1. Remove the Manta Gear by pressing and holding the latch on the
Manta Gear. Then twist it until the white dot on the Manta Gear is
lined up with unpainted red dot on the Focus Ring (note: the
unlocked icon).
2. Pull the Manta Gear off the lens.
3. Remove the Focus Ring by reversing the steps 1 and 2. above The
white dot and the unpainted red dot will not be lined up after step 2,
allowing you to slide the Focus Ring off your lens.
