Nauticam is dedicated to designing the finest underwater imaging products available. The new EMWL - Extended Macro Wide Lens - takes that innovation to the next level. The EMWL allows you to shoot macro, wide angle and combine the styles to create images we only dreamed about previously!

EMWL
The EMWL was built to work with several popular macro lenses and is optimized for both stills and video. It is a wet mount design so the lens can be attached and removed underwater. This increases the versatility of the entire system and other accessories like SMC and CMC macro converters can also be used. It is a modular design with three individual pieces that make up the EMWL, the Focusing Unit, the Relay Module and the Objective Lens. Nauticam has made components optimized to work with different camera manufacturers and their macro lenses, as well as choices for four unique perspectives. Let’s look at the individual parts and dive a bit deeper into the EMWL.

EMWL Focusing Unit
To ensure the best results across a range of cameras, four focusing units were designed and each unit is custom designed optically to work with the recommended primary lenses. You will want to purchase the correct version for the lens you are using. The EMWL is very sharp, and has very good contrast, autofocus works extremely well. This is a significant advantage compared other available relay lenses. You also have the option to add a manual focus gear. Lens adapters such as the Nikon FTZ, EF to EOS R or the Sigma MC-21 can also be used. The focusing unit is the part that is connected closest to your port, it is designed with 6 glass elements in 3 groups and attaches via the Bayonet Mount System.

EMWL Relay Lens
The next piece that attaches to the front of the focusing unit is the Relay Lens. It was designed to the highest standard with 14 glass elements in 10 groups. The EMWL Objective Lenses generate an inverted image, making it appear upside down. The Relay Lens corrects the inverted image and relays the image back to the focusing unit and sensor. It is 150mm in length and only 62mm at its widest point. This allows the front of the EMWL to be placed extremely close to your subject while keeping the bulk of the camera system and the photographer at an extended distance. It also opens up creative possibilities for videographers to shoot motion shots in tight spaces. Imagine a push through eel grass to reveal a juvenile bat fish or a pull back from a small subject to reveal the burrow it lives in. All three Focusing Units use the same Relay Lens. 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 monitor that can correct for the inverted image in the EVF or LCD.

EMWL Objective Lenses
The final piece that attaches to the front of the Relay Lens is the Objective Lens. There are four different versions with varying degrees of angle-of-view. You would choose one based on the look, subject or type of image you would like to produce. These, like the other two parts, can all be put together and disassembled underwater. You could keep all four objective lenses with you and swap out when needed. You can shoot these just like you would any other lens, but the real magic happens when you get up close to your subject. The 160°, 130° and 100° objective lenses will focus as close as the front element and the 60° objective lens can focus as close as 15mm. You could fill up most of the frame with a nudibranch and still have room for a diver in the background! The EMWL is a great tool to boost your creativity.
160° Objective Lens 87226
This is the widest of the four Objective Lenses. It is perfect for larger macro subjects or any image where you want to see more of the background. The small front element offers many creative opportunities.
130° Objective Lens 87223
This ultra wide Objective Lens is designed with 9 elements in 7 groups. The image quality rivals the best wide angle lenses so feel free to shoot it for traditional wide angle shots or macro subjects with background elements.
100° Objective Lens 87222
This is an extremely versatile angle of view. It is the smallest and sleekest in physical size making it a good choice for timid subjects and tight spaces. It is designed with 9 elements in 6 groups. An angle of view of 100° is still a lot of background space for small macro subjects or to shoot wide angle with. A 16mm lens on FF is 107° for comparison.
60° Objective Lens 87221
For a narrower angle-of-view or if you would like the background elements to look more compressed, than the 60° objective lens is the perfect choice. It is designed with 9 elements in 6 groups. There are three focusing ranges that can be set on the lens, ∞-55mm, 55-25mm and 25-15mm. I would suggest setting it to the ∞-55mm setting and adjust to one of the closer settings when working extremely close to a subject. The closer setting work similar to an extension tube by moving the lens further away from the sensor.

Mounting
There are three mounting options for the EMWL.
Bayonet Mounting
The EMWL focusing unit ships with a bayonet mount attached. You just need to add the appropriate Bayonet Mount Converter to the front of your port. If you wish to use a Super Macro (SMC-1 or SMC-2) or Compact Macro Converter (CMC-1 or CMC-2), they can be attached with an optional Bayonet Mount Adapter.

- M77 Bayonet Mount Converter II 83251 for Nauticam 77mm threaded ports
- Bayonet Mount Adapter 83214 for SMC and CMC
Flip Holder For The EMWL
There is also an optional flip holder for the EMWL. It is a double flip design with one dedicated flip for the EMWL and another available for a SMC or CMC. Please note: Ports shorter than 80mm are not compatible with the flip holder.

M67 Threaded Mount
The last option is a M67 mount for the EMWL to thread the EMWL directly to a M67 port.
