The Olympus OM-D E-M5 II Camera
The E-M5 II has refinements large and small, from an additional stop of performance of the 5 axis stabilization to a fully articulated LCD; the “II” is an impressive update. Little touches include a lockable mode dial and two additional programmable buttons. Olympus clearly listened to users when it made the Super Control Panel on by default (no more hunting in the menu to try to enable this). The camera also now allows the info screens to be customized, such as the histogram, level and highlight/shadow warnings that can be shown together. Long exposure fans will like the LiveTime feature – realtime long exposure shooting – very cool.
For underwater photographers, the biggest improvement is a serious upgrade to the electronic viewfinder, which now sports a 2.36m dot LCD (same dot count as the revered E-M1). It is hard to shoot what you can’t see, and the upgraded EVF goes a long way towards improving vision, especially when paired with a Nauticam enhanced viewfinder.
For the videographer, the E-M5 II significantly upgrades the frame rate (60 fps) and bitrate (77 Mbps), with both ALL-I and IBP recording modes. It is the first Olympus to offer focus peaking while shooting video, and gains a microphone socket. The video here can take advantage of the in-camera image stabilization, allowing for smoother handheld video clips.

The NA-EM5II Housing
The new housing from Nauticam is an evolutionary marvel. This housing is true to it’s NA-EM5 predecessor: highly configurable with the separate handle design (see CFWA Monster, below). This design allows the user to configure handles independently. One very desirable mode is to outfit the housing with a single left handle (Flexitray or Easitray), accompanied by a handstrap on the right. This helps to make rig as small as possible, with the comfort and security of the handstrap. Two handle options are available, as well as going as small as possible, with no handles or trays, ideal for the freediver shooting ambient light, for example.
More than just good looking, this is a rugged housing, ready to tackle thousands of hours of underwater abuse. Crafted from solid aircraft aluminum, the housing can reach depths of 100m with ease. The effortless (but secure) single rotating housing latch opens the housing back. The camera drops in easily, with no controls needing to be preset. The rear mounted housing o-ring makes maintenance simple. Dual fiber optic synch ports are standard and take advantage of the supplied Olympus accessory flash. To make the most of the E-M5’s excellent electronic view finder (EVF), Nauticam has crafted an optional rear acrylic display window that includes a mount for installation of Nauticam’s acclaimed 45º and 180º magnified view finders, providing the ultimate in composition and focus ability.
Like all Nauticam housings, particular attention is paid to ergonomics. Buttons and dials are easy to access, with minimal reach required. The Olympus Main and Sub dials are easily accessed by thumb or forefinger with no need to release grip on the housing while adjusting aperture and shutter speed. The important Fn1 and Fn2 buttons are just as easy to reach and can be programmed for a multitude of functions. A few of the useful settings are AF Lock, One-touch White Balance, Manual Focus, ISO and Exposure Compensation. Switching between LV and the EVF is a snap and a quick press of the Info button can show or hide Olympus’ new LV Super Control Panel on the OLED screen for quick access to many critical settings. The mode dial can easily be turned through the typical P, A, S, M, Movie mode and some “easy shooting modes”. Controls need to offer a proper “feel” and Nauticam’s patented two-stage lever shutter release allows for natural, precise focus and shutter release activation. Every one of the features on the new NA-EM5 is engineered to the same exacting tolerances of Nauticam’s now famous line of DSLR housings. That quality will surely be reflected in every picture taken with this remarkably powerful imaging system.
Premium Professional Optics
It’s all about the glass, and lenses are the key to terrific photography. The m4/3 system supports a large range of high quality lenses produced by Olympus and Panasonic (partnering with Leica), and third party lenses from Sigma are starting to appear. Several lenses that perform extremely well underwater are available (and reasonably priced!). Some examples:
- Olympus M.ZUIKO DIGITAL ED 12-50mm F3.5-6.3 EZ: The ultimate jack of all trades tool, this lens covers a very usable mid range, and features a unique macro mode. Shoot dolphins and nudibranchs on the same dive!
- Panasonic Lumix G Fisheye 8mm/F3.5: This 180º fisheye lens focuses close and is razor sharp. Combines with a small port, there is no better CFWA (close focus wide angle) option on the planet.
- Olympus M.ZUIKO DIGITAL ED 60mm f/2.8 Macro: This is an ideal macro lens for m4/3, and by adding the Nauticam CMC, it becomes a super macro monster. Imagine filling the entire width of the frame with something only 8mm wide!
- Panasonic Lumix G Vario 7-14mm f/4.0 ASPH: The 7-14mm is a rectilinear lens, ideal for shooting people or sharks or wrecks… subjects where the fisheye distortion is not welcome. On the wide end, this lens 114º wide, ideal for getting close to subjects to reduce the amount of water shot through. But a zoom gets to 75º – ideal for reaching out to that subject that is a little more skittish. The very similar Olympus M.Zuiko Digital ED 9-18mm f/4.0-5.6 can serve the same basic role at a lower cost.
There are many more options for the underwater photographer, including any of the several 14-42mm options, the Panasonic Lumix G X VARIO 12-35mm F2.8 ASPH. POWER O.I.S., Olympus M.ZUIKO DIGITAL ED 12-40mm f/2.8 PRO, Panasonic Lumix G Vario 12-32mm f/3.5-5.6 ASPH, Panasonic Lumix G 14mm F2.5 ASPH, and the Leica DG Macro Elmarit 45mm F2.8 ASPH.
Nauticam magnifying viewfinders are available in Angled 45º and Straight formats and both have external dioptric adjustments for dialing in perfect correction matched to the photographer’s eyesight.

Patented Port Locking System
Unveiled on the very first Nauticam DSLR housing in 2009, this locking lever has become a signature of the Nauticam brand. No twisting or threading action is required to mount a port, and it locks securely in place with this lever. Nauticam also offers locking port extensions, meaning a dome will never twist, even when used with a long extension ring.

The secure single rotating housing latch opens the housing back allowing for quick and easy battery or media changes.
Locking Camera Tray
A locking camera mount system secures the camera in place, providing strength and precise positioning even when a heavy lens is mounted.
