Nikon D780 Underwater: Initial Thoughts and Review
Nikon D780 Underwater: Initial Thoughts and Review
The Nikon D780 is proof that Nikon is not done with their DSLR cameras..... yet. In fact, the release of the Nikon D780 is particularly exciting because the camera represents an elegant hybridization of mirrorless and DSLR technology. This is evident in the D780's new phase-detect AF system in live view that is capable of autofocus tracking.
With a 24.5 megapixel, full-frame sensor capable of shooting 4K video @ 30fps, the Nikon D780 is equivalent to a DSLR version of the Nikon Z6. For underwater photographers looking for diverse AF systems, including an optical viewfinder AF system similar to the D5, the D780 will be a great option.
Whether it's a better option for underwater photography than the slightly cheaper Nikon Z6, it's hard to tell. If you want the benefits mirrorless photography including edge-to-edge focus points, no need for expensive magnified viewfinders, IBIS, and z mount lenses, then the Nikon Z6 is going to be a future-proof option. If you're not quite ready to step out of the DSLR world, then the Nikon D780 is going to be the way to go. In fact, the new phase detect AF system in live view gives it a direct advantage over the Nikon D850.
So lets take a deeper look into what makes this camera so excellent and the range of accessories available for underwater creatives....

The most exciting update made to the Nikon D750 has been the autofocus system. In live view, the Nikon D780 has the guts of a Nikon Z6 phase detect autofocus system. This means quick focus with AF tracking.
The 24.5 MP sensor itself appears to be the same as the Nikon Z6. It is backside illuminated with dual gain ISO. It is expected to perform much better at higher ISOs and has an improved ISO range of ISO 100 - 51,200.
The D780's video capability is also significantly better than the Nikon D750. It appears that the D780 has inherited video from the Z6 - with an ability to shoot 4K up to 30 fps, with the full width of the sensor.
Burst modes and slow shutter speeds have also been improved on the Nikon D780. The Nikon D780 can shoot 12 fps burst in the silent live view mode. Landscape and astro photographers will appreciate shutter speeds of up to 900 seconds, without the need for a remote trigger.

Body and Build
The Nikon D780 is built like your standard Nikon DSLR. It's durable, ergonomic, and completely weather-sealed. The largest physical change from the D750 is that the D780 has an additional dedicated AF-on button. At 840 grams it's not particularly light weight or heavy. As with any DSLR, it has an optical viewfinder which many photographers still prefer to the EVF of mirrorless cameras due to the benefits of clarity.
A Radical New Live View System and Improved AF
For the entirety of their existance, DSLRs have been plagued by bad live view autofocus. Because of this, generations of photographers rarely consider using live view systems in their photography. However, for underwater photographers, view finders are difficult to look through, and magnified viewfinders can be prohibitively expensive. This is one of the big reasons why mirrorless cameras are a benefit to underwater photographers. Well, the D780 is slated to be just as good as a mirrorless camera in live view - featuring a 273 point phase detect AF system capable of AF tracking. This is going to open up a world of possibilities to underwater photographers and videographers. This new system basically makes the Nikon D780 a hybrid DSLR-mirrorless camera.
Beyond of the live view AF, the 51 point AF system through the viewfinder is said to be borrowed from the flagship D5. Whether or not it performs as well....we can't wait to get the camera in the water to find out!
Better Burst and Expanded Shutter Speeds
For an entry level full-frame DSLR, the D780's burst rate is quite alright at 7 fps. In live view, using silent shutter, it's as high as 12 fps! This should be pretty exciting for underwater photographers that shoot quick pelagic subjects who don't want to spend the extra money on a faster camera.
For landscape and astro photography, the expanded shutter speed range of 900 seconds to 1/8000 seconds is exciting. Photographers won't need to use a remote trigger for long exposures under 900 seconds!
Improved Video Capability
The video capability of the Nikon D780 is one of the most exciting features it has to offer. At 4K resolution up to 30 fps, it's a serious upgrade from the outdated D750. The video capability and quality is similar to the Nikon Z6 which uses the full width of the sensor to shoot 4K - producing very detailed video. The excellent live view AF system will contribute to the great continuous AF in video mode. The D780 should also have improved color compared to it's predecessor. Finally, the Nikon D780 is capable of shooting 10-bit N-log or HLG picture profiles - which preserve detail after processing. It is, however, important to note that the D780 doesn't have in-body image-stabilization, which is a huge benefit of the Nikon Z6.
What can we say....the battery life is great! At 2260 shots, it's rated almost 7 times longer than Z series cameras! For underwater photographers and videographers that means more shooting time underwater and less worry about having to change batteries topside. In fact, it should be possible to get multiple days of diving on a single battery!
The Nikon D780 is a very exciting DSLR for underwater photography. With a vastly improved live view AF system, it is a cross between a DSLR and mirrorless camera. Users will reap the benefits of both designs. With AF tracking a phase detect AF, it will be a good camera for underwater photographers that want to track there subjects and don't want to use a small viewfinder. For photographers that like the clarity and dynamic range of an optical viewfinder, they'll get that too....along with an excellent 51 point AF system.
The image quality from the Nikon D780's sensor has proven to be excellent for a mid range full-frame DSLR, as it is likely tried and tested with the Nikon Z6. Improvements in low light capability should be noticeable which will be welcomed especially by cold water divers. We're hoping for less noise in our photos compared to the Nikon D750.
Ultimately, the Nikon D780 gives photographers who aren't ready to leave the DSLR world for mirrorless cameras, time to adjust to a changing world. It's certainly a worthy upgrade from the D750 that places it on the other side of the mirror from the Z6.
Nikon D780 for Underwater Video
The Nikon D780 just might be Nikon's best DSLR for Underwater video. It offers 4K video using the full width of the sensor (downsampled from 6K). This ensures a higher level of detail than normal 4K video. Nikon's colors have improved quite a lot in their video from previous generations of the camera. The D780 also offers 10 bit logarithmic recording which should please anyone who likes to post process their video to bring out as much detail as possible. Finally, the phase detect live view AF system is one of the best on the market for underwater video.
Compared to the Z6, the Nikon D780 is similarly capable when it comes to video. However, it does not have any in-body image-stabilization. For this reason we recommend the Z6 over the D780 for underwater video.
The Nikon D780 is the perfect camera for any underwater photographer looking to step into a full frame system and doesn't want to go mirrorless. The D780 has a huge selection of F mount lenses with plenty of great options for underwater creatives. It offers an amazing AF system, including a groundbreaking AF system for live view. This makes it a good upgrade for DSLR users who are looking to use their LCD underwater and don't want to be hindered by slow AF. The D780 doesn't quite have the resolution of the D850, but the sensor is tried and true and brings truly excellent image quality to the table. The video is also the best of any Nikon DSLR. So for DSLR users that want a Nikon with good video, this is the camera for you.
