Best Sony Full Frame lenses for Underwater
Let's look at the best Sony full-frame lenses for underwater use. The Sony E Mount is the standard for all Sony Mirrorless cameras, both full frame and APS-C sensor sizes. Look for the "F" designator in the lens description to know if it is designed for their full frame sensors, such as Sony FE 16-35mm. All lenses will fit on both types of cameras, however a cropped sensor lens "E" on the full frame cameras "FE" will result in the full frame camera shooting in "cropped sensor" mode. See below for our list of great Sony lenses for underwater photography with the full frame Sony mirrorless cameras including, but not limited to the A7RII, A7RIII & A9.
Sony FE 12-24mm F4 Lens
*Ultra Wide Without Fisheye Distortion"
The Sony FE 12-24mm Lens offers an ultrawide rectilinear field of view which is great for shooting large subjects that you are able to get close to. Curious animals, such as sea lions, and large man-made objects like shipwrecks are great subjects with this lens.
Sony FE 16-35mm F4 Lens
*Perfect All-Around Wide Angle Lens"
The Sony FE 16-35mm F4 Lens is a perfect underwater choice. It's wide enough to capture stunning reef scenes, big animals, wrecks and more, but also offers a longer zoom range for when you can't get as close as you'd like. In addition it makes a great topside wide angle lens. This is our pick if you're looking for one solid wide angle lens. We recommend the F4 version over the Sony FE 16-35mm F2.8 as most underwater photography is shot at smaller apertures so it is unlikely the F2.8 speed is needed and the F4 has a much nicer price tag! Although the F2.8 is a higher quality version of the F4.
Sony FE 28mm Lens + Fisheye Conversion Lens
*Lightweight, Ultra-Wide Fisheye View"
This Sony FE 28mm Lens with the Fisheye Conversion Lens offers a much wider field of view than both the 12-24 or 16-35mm rectilinear lenses. In addition a smaller dome port is needed with Fisheye lenses, and the overall weight of these two lenses compared to using a wet wide lens is much less. This makes it a great option for those looking to keep light on travel restrictions.
Sony FE 28mm Lens + Wet Wide Angle Lenses
*Flexible Wide Angle"
The Sony 28mm F2 lens pairs perfectly with high quality wide angle wet lenses such as the Nauticam WWL-1 or AOI UWL-09. Using the 28mm lens behind a flat port with the wide angle lens attached gives you the ability to remove the wide lens during the dive and shoot a tighter shot. It's effectively like diving with two lenses at once.
Sony FE 28-70mm F3.5-5.6 Lens + Nauticam WACP
*Revolutionary Lens / Conversion Port"
Sony FE 90mm F2.8 Macro Lens
*High Quality Super Macro"
Sony FE 50mm F2.8 Macro Lens
*Great All-Around Macro Lens"
ALL AROUND - MEDIUM FOCAL RANGES
Sony FE 24-70mm F4 Lens
*High Quality, Great for Video"
The Sony 24-70mm F4 adds a bit wider angle of view than the standard kit lens (28-70mm) making it a nicer choice for underwater. It's great for those subjects like medium to large sized animals you can't get close to, or for video work when a bit of extra zoom is desired. The consistent F4 aperture means a nice bright lens regardless of zoom.
Sony FE 28-70mm F3.5-5.6 Lens
The standard kit lens for the Sony Full Frame Mirrorless cameras, the Sony FE 28-70mm lens is your basic, mid-rage lens choice. This is good behind a dome port for animals you can't get too close to. In addition this lens pairs perfectly with the high end Nauticam WACP if looking for a top of the line wide angle solution.
Sony FE 28mm F2 Lens
*Perfect to Pair with Wet Lenses"
The Sony 28mm lens is a standard focal length prime lens which works great with either the Fisheye Conversion lens for a less expensive alternative to good wide angle, or pairs really well with several wet lenses. For top quality use with Nauticam's WACP (see above), or for more flexibility pair with Nauticam WWL-1 lens, or the Kraken Sport KRL-01.
