Without Relay Lens
Setup
The relay lens is 150mm in
length and only 62mm at its
widest point.
This allows the front of EMWL
to be placed extremely close to
the subject while keeping the
bulk of the camera system and
the photographer at an
extended distance.
It is possible to use the EMWL
without the relay lens if you do
not need the extended working
distance, but you will want a
camera or a monitor that can
correct the inverted image in
EVF or LCD.

The EMWL modular system is designed for exchangability underwater, each module can assemble and disassemble in
water. When entering the water or each time after interchanging lenses, air bubbles might be trapped in between lenses.
The air release ring is to allow water to pass through and therefore releasing the air bubbles.
* Interchanging lenses in sandy bottom and murky water is not recommanded.
* We recommand to open and close the air release ring only when the water is clear.
There are 2 types of air release ring :

wrapping.
