Nauticam Full Frame Straight Viewfinder 40°/ 0.8:1

The Full Frame Straight Viewfinder employs entirely new optics to allow distortion free viewing without clipping the image frame. With the new viewfinders, reviewing images in playback or navigating the menus through the EVF has never been so easy.

32º/1:1 vs. 42º/0.8:1

Because different photographers have different needs and priorities, Nauticam offers the Full Frame Straight Viewfinder in two options. The 1:1 viewfinder option offers the most magnification available for underwater viewing while preserving the image field and surrounding data on most cameras. This viewfinder is a breakthrough in performance on high resolution EVFs and is an absolute joy on traditional DSLRs. The level of detail rendered is unequaled in the industry.

For those utilizing cameras with known EVF challenges such as the Sony’s A1 and A7SIII cameras, or just for the photographer who wants as much working room on the viewfinder field-of-view as possible, Nauticam offers the new 0.8:1 version. The 0.8:1 viewfinder offers an equally crisp and bright EVF display as the 1:1 viewfinder, with slightly less magnification for uncompromising corner to corner image viewing or better imaging of shooting data.

Hassle-free Underwater Dioptric Adjustment

The much-loved dioptric adjustment is still featured and allows for easy eyesight adjustment in-water without disassembly of the viewfinder as well as simple installation and removal that takes only seconds.

Tool Free Installation

The Nauticam Full Frame Angle Viewfinder can be installed in seconds without any tools.  The viewfinder is a direct replacement of the stock 0.66X viewfinder on DSLR and many full-frame mirrorless housings but requires an easily installed adapter on certain MIL housings. The viewfinder can also be rotated to allow the camera to be used in portrait orientation.

Whether future proofing a viewfinder purchase for your current rig, or patiently waiting for a viewfinder worthy of the latest pro mirrorless camera you are diving, these cutting-edge viewfinders are the new industry standard to be looking at.
