Mid-range zoom rectilinear lenses are often favored by photographers working on land because of the versatility they provide. This need for versatility is even more important underwater when you are not sure if you will need a wide angle or a close-up lens, and don’t want to fiddle with heavy, cumbersome wet lenses.
One all around lens that works especially well in this situation is the Nikon Z 24-70mm f/4 S as it offers an economical way to shoot a broad range of subjects, from very small to fairly large critters or objects; wide angle views one moment, closeups the next, and everything in between.

First announced in 2018, it was the first zoom lens made for the Nikon Z system and since then has been an essential part of the Nikon lineup. It requires no adapters when used with Nikon mirrorless systems such as the Z6, Z7, Z8 and Z9.
Empowered by the Z system's larger mount and cutting-edge imaging advancements, the Z 24-70mm f/4 S lens delivers great sharpness, vibrance, and even lighting across the entire frame.

When photographing sharks, the action tends to shift quickly from long shots of sharks to close ups as those same sharks swim close to the camera. A zoom is ideal for reacting to the changes in distance. // Nikon Z6 • 31mm •1/250• f/9• ISO 450 © Glenn Ostle
For large subjects the Z 24-70mm f/4 S offers wide focal lengths, and for small subjects it provides close focus of less than 1 foot (11.8-inches).
Other features of the Z 24-70mm f/4 S lens include:
- Aperture: f/4 – f/22
- Filter size: 72mm
- Dimensions: 3.1 in. (77.5 mm) x 3.5 in. (88.5 mm)
- Weight: 17.7 oz. (500 g)

The sea lions that frolic in the Sea of Cortez are fast swimmers and can quickly change from being in the distance, to being right in front of you peering into your lens. Once again, a wide zoom helps capture all the action. // Nikon Z6 • 24mm • 1/125 • f/10 • ISO 320 © Glenn Ostle
Nikon has recently announced two new Z 24-70mm models including the Z 24-70mm f/2.8 S for softer backgrounds when shooting wide open, as well as the Z 24-70mm f/2.8 S II billed as “the world's first 24-70mm f/2.8 to feature an internal zoom design, which contributes to upgraded weather resistance, faster AF performance, and a 16% reduction in weight compared to the previous generation.” Both new models come at a steeper price than the original but offer a significant number of improvements.
If you are looking for a rectilinear Z-mount lens for underwater versatility, the 24-70mm f/4 S or the new f/2.8 S or f/2.8 S II models are great choices.
