Nauticam EMWL Extended Macro Wide Lens Focusing Unit for Canon SLR & Mirrorless Cameras

• Canon EF 100mm f/2.8L Macro IS USM
• Canon EF-S 60mm f/2.8 Macro USM

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 to 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. 

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 three unique perspectives. Let’s look at the individual parts and dive a bit deeper into the EMWL.
