The Spectrum Filter SF -1.5 is designed to compensate for the light absorption of all water colors and therefore provides a smooth, well balanced light spectrum to the sensor of your camera. This greatly improves the color rendering of your images and adjust the color coordinates close to daylight for outstanding results with manual white balance.
KELDAN Spectrum Filters explained from Wetpixel on Vimeo.
The Spectrum Filter SF -1.5 has a compensation depth of 3.5m. At this depth the filter makes a pertfect compensation of the light absorption of the water column. The camera then sees a daylight spectrum just like shooting at the surface.
The filter is designed to provide optimal performance for any water color from blue to green water. It works best within a depth range of 2 to 15 meters. The filter has a damping equivalent to a loss of 1.5 stops.
For deeper depth we recommend to use either SF -3.5 B (for blue water) or SF -3.5 G (for green water)
The filter can be easily cut to the needed size. The substrate of the filter is a thin plastic sheet.
Three pcs. filter sheets with the size 80x80 mm are shipped in one envelope.

Macro to Wideangle Lens 1 (MWL-1)
€2,050.00*
The Nauticam MWL-1 is a revolutionary concept! It is a wet-mounted ultra wide lens (meaning it can be attached and removed underwater) designed to be used with a 60mm full frame equivalent macro lens that results in an ultra-wide 150º field of view. The MWL-1 can focus from the lens' front element to infinity. Ultra wide angle and macro perspectives are now available on the same dive - even with full frame DSLR systems.
MACRO TO WIDE ANGLE LENS 1 (MWL-1)
The MWL-1, similar to other Nauticam underwater optics is made from precision ground optical glass with advanced anti-reflective coatings to eliminate glare and internal reflection.
MACRO AND WIDE WITH ONE CAMERA LENS!
For many photographers, especially those moving up to an SLR or mirrorless system, there is trepidation at being locked in to either macro or wide angle on a dive. With compact systems that featured wide zoom range lenses that, when paired with corrective optics, could allow for wide angle or macro on the same dive. When moving to an interchangeable lens and port system you would previously have been committed to either wide angle or macro for a given dive.
CLOSE FOCUS WIDE ANGLE IMPACT
With the introduction of the MWL-1, not only can you switch between wide angle and macro on the same dive you can also capture unique close focus wide angle images of macro subjects. This technique works best when a macro subject can be placed very close to the lens where exaggerated perspective makes it pop out from an ordinary background.
The MWL-1 excels at smaller apertures and full-frame shooters will get optimal results at F16 or higher.
MULTIPLE MOUNTING OPTIONS
With two mounting options, Nauticam's bayonet system or one of two available flip mounts, the MWL-1 can be quickly engaged or disengaged or even swapped for an CMC-1, going from wide angle to super macro in seconds.#

Wet Wide Lens C (WWL-C) by Nauticam
€1,030.00*
The next evolution of the WWL-1 is here! As the versatility and capability of compact cameras increases, Nauticam has developed a smaller and lighter water contact wide angle lens tailored specifically to the compact camera user. Designed from the ground up to match the compact camera's form factor without sacrificing optical quality, the WWL-C is a powerful addition to not only Nauticam compact housings but also, via an optional adapter, to those from other manufacturers such as the Olympus TG-6 and their PT-059 housing.
Introducing Wet Wide Lens for Compact Cameras (WWL-C)
With the original Wet Wide Lens, the WWL-1, Nauticam used computer aided lens design software to create an underwater-specific corrective lens that allowed for an unprecedented 130º field-of-view with full zoom-through optics and extreme close focus capabilities. The WWL-1 wasn't just for higher end cameras that already benefitted from interchangeable lenses to attain better image quality, the WWL-1 was designed to work with a variety of cameras that featured a 28mm equivalent lens including compacts and micro-four thirds.
Delivering a stunningly sharp 130º field-of-view with 24mm equivalent lenses, the WWL-C also features zoom-through capable optics.** The WWL-C features a pre-installed metal buoyancy collar and a non-removable metal dome shade.
The WWL-C will also feature an updated quick-release Bayonet Mount. Lenses that feature the new Bayonet Mount II will not be compatible with previous Bayonet Mount adapters but all Bayonet Mount lenses will be able to be used with the new Bayonet Mount II Bayonet Mount Adapters without modification.
In the sidebar you will find a list of anticipated housing compatibility along with the supported focal-length range as well as the necessary port configuration for the Bayonet Mount II standard.
Compact Housings
The WWL-C is designed around the 24mm focal length which is commonly the widest focal length for fixed-lens compact cameras. While the WWL-1 was also able to deliver 130º field-of-view it required that the camera's lens be zoomed in slightly to 28mm. With the WWL-C, there's no more need to zoom to avoid vignette! This also means that more of the camera's zoom range is available.
The new NA-TG6 (17816) for the Olympus Tough TG-5 and TG-6 cameras is WWL-C ready out-of-the-box as it comes with the new Bayonet Mount II converter pre-installed. With the TG-5 and TG-6 the WWL-C allows for use of the 25-100mm zoom range!
For those compact housings with the N50 interchangeable port system, there are new short ports with Bayonet Mount II adapters pre-installed.
Configurations for some of the latest models:
Sony RX100 VII in the NA-RX100VII use (38705) N50 Short Port 17 with Bayonet Mount with a usable zoom range of 24-30mm
Canon PowerShot G5X Mark II in the NA-G5XII use (38703) N50 Short Port 25 with Bayonet Mount with a usable zoom range of 24-50mm
Panasonic Lumix DMC-LX100 II in the NA-LX100II use (38704) N50 Short Port 22 with Bayonet Mount with a usable zoom range of 24-30mm
Complete configurations for all supported models can be found on the Port Chart for the WWL-C.
Mirrorless M4/3 Housings
The WWL-C is not just for compact cameras! The Panasonic LUMIX G VARIO 12-32mm F3.5-5.6 ASPH. MEGA O.I.S. lens, when used with (36165) N85 Power zoom macro port 29 and the (83250) M67 to bayonet converter II allows for the use of the full 12-32mm zoom range.
Mirrorless APS-C Housings
Sony, Canon, Nikon and Fuji Mirrorless APS-C can all benefit from the WWL-C. The Sony SELP1650 E PZ 16-50mm F3.5-5.6 OSS offers excellent performance from 17-50mm with only slight vignetting at 16mm. The compact size of the WWL-C works in tandem with the low profile series of Nauticam housing for Sony's E-mount APS-C series of cameras such as the NA-A6600 and NA-A6400 to provide a travel-friendly package that doesn't compromise optical quality.
Adapter for Olympus PT058/PT059 Housings
Using the WWL-C with the Olympus PT058 and PT059 Housings for their Tough TG-5 and TG-6 cameras is now also an option with the (83256) Bayonet Mount Converter for Olympus PT058/059.

Spectrum Filter SF -3.5 G Film 60x60
The Spectrum Filter SF -3.5 G is designed to compensate for the light absorption of green water colors and therefore provides a smooth, well balanced light spectrum to the sensor of your camera. This greatly improves the color rendering of your images and adjust the color coordinates close to daylight for outstanding results with manual white balance.
The Spectrum Filter SF -3.5 G has a compensation depth of 6m. At this depth the filter makes a pertfect compensation of the light absorption of the water column. The camera then sees a daylight spectrum just like shooting at the surface.
The filter works best for green water within a depth range of 6 to 20 meters. The filter has a damping equivalent to a loss of 3.5 stops. Normally low noise cameras that allow to shoot at ISO 1600 or higher are required when using this filter.
IMPORTANT: If you experience problems wit too low light level switch to a lighter filter such as the SF -1.5 (loss equvalent to 1.5 stops). The use of a lighter filter is always the better option than using no filter at all!
The filter can be easily cut to the needed size. The substrate of the filter is a thin plastic sheet.
