Nauticam Extended Macro Wide-Angle Relay Lens EMWL

Combines Macro with Wide Angle Shooting Style


The Nauticam Extended Macro Wide-Angle Lens EMWL is a long bugeye wet lens which incorporates wide angle with macro, truly a unique shooting style. It is built to work with popular macro lenses and shoot both stills and video. It is a wet lens so the lens can be attached and removed underwater. This makes it a very versatile lens and can even work with diopters such as Nauticam SMC and CMC. The lens design is long and narrow which enables you to put the ens extremely close to your subject while keeping the bulk of the camera system at a distance.

The lens has a modular designed, it is comprised of 3 parts - Focusing Unit, Relay Module and Objective Lens. It is optimized to work with different cameras and macro lenses.

How to Build Your EMWL

  • Choose the Focusing Unit appropriate to your lens
  • Choose the Objective Lens - preferred degrees of angles of view. There are 3 options to choose from  60°, 100°, 130°

Lens Components

Focusing Unit

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. 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 options to choose from Canon, Sony and Nikon/Micro Four Thirds

Compatible Lenses:

Canon   Sony   Nikon & Micro 4/3
Canon EF 100mm f/2.8L Macro IS USM   Sony SEL90M28G FE 90mm F2.8 Macro G OSS   Nikon AF-S VR Micro Nikkor 105mm f/2.8G IF-ED
Canon EF-S 60mm f2.8 Macro USM for APS-C       Olympus M.Zuiko Digital ED 60mm f2.8 Macro


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.


Objective Lens

This completes the EMWL lens and there are three different versions with varying degrees of angle-of-view - 130°, 100° and 60°. You can swap the objective lenses underwater to achieve the best results. You focus as close as the front element with the correct setting.

130° - Widest of all objective lenses and is made up of 9 elements in 7 groups. It is perfect for larger macro subjects or any image where you want to see more of the background.

100° - The most versatile of the 3. It is the smallest in physical size making it a good choice for timid subjects and tight spaces. It is designed with 9 elements in 6 groups.

60° - If you like a narrower angle-of-view or would like the background elements to look more compressed, this one is for you. There are three focusing ranges that can be set on the lens, 00-55mm, 55-25mm and 25-0mm. It is designed with 9 elements in 6 groups.


The EMWL uses the Nauticam Bayonet Mounting System II. You can easily attach or remove the lens underwater.
