Nikon D780 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.

 

In order to get a true sense of what a hybrid DSLR-mirrorless camera means for underwater photographers, we took the Nikon D780 diving in the warm, tropical waters of Maui, Hawaii with an Ikelite D780 underwater housing and dual Ikelite DS161 strobes. Overall we thought the system had the same great, ergonomic feel of a Nikon DSLR with a vastly improved live-view autofocus system. This enabled us to forgoe using magnified viewfinders if we so chose and opened a new world of DSLR video, similar to the amazing results we often see with the Nikon Z6.

Nikon D780 Compared with Nikon D750

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. 

 

For underwater photographers, the largest considerations for upgrading from the D750 will be the value of having quick live view autofocus and a good focus system for underwater video (as well as excellent 4K video and color science).

Nikon D780 Key Features:

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. 

Pro Tip: Before taking your Nikon D780 underwater, it's a good idea to customize your i menu so that all essential controls (e.g., ISO, Focus Area Selection, AF modes) are just one button press away. If you forget this the you can end up having to push the ISO button while turning the back dial, which can be very annoying to do in an underwater housing. 

A Radical New Live View System and Improved AF

 

For the entirety of their existance, DSLRs have been plagued by slow 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.

 

The Nikon D780 has the unique benefit of offering two entirely different AF tracking capabilities - the traditional 3D AF tracking through the viewfinder and AF tracking in live view. Both can be fairly useful while shooting underwater - especially when trying to keep track of subjects that move suddenly or predictably. We tested the Nikon D780's AF tracking capability quite extensively during our Hawaiian dives. The AF tracking worked very similarly to the Z6 - it works great in some situations and not in others. It's necessary to be close to the animal being tracked, and even then it isn't always the most accurate. The Sony A7R IV still has some of the best AF tracking on the market. But the important takeaway from the D780 is that you can freely choose live view and viewfinder AF and both are excellent. 

 

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. 

We thought the video we captured with the Nikon D780 on par with the video from Nikon's recent mirrorless offerings. This officially makes the D780 Nikon's best DSLR for underwater video, and a serious contender for the underwater video camera market - despite not having IBIS. 

 

Battery Life

 

What can we say....the D780's 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. 

When we shot only in live view, we found the battery life to be reduced and similar to the battery life with the Z6 - as would be expected. That being said, we were able to get 3-4 dives out of a battery even if we were shooting just in live view. When shooting through the viewfinder, it should be possible to get significantly more dives. This is a big positive for anyone who wants to stick to DSLR's for the added battery benefit - especially photographers that dive in remote locations and don't have an easy way to change batteries on the fly.

Nikon D780 for Underwater Photography

 

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. 

 

Shooting the D780 underwater was an excellent experience. The camera adapted nicely to a wide range of dive conditions. The Nikon 8-15mm fisheye was a great choice when diving in the deep blue waters of Molokini. The Nikon 105mm macro was very useful for capturing macro patterns and tiny critters on hte reef. Overall we thought the images speak for themselves - the image quality is excellent. We thought the details and dynamic range in the images stands up to other professional Nikon DSLRs and mirrorless cameras of the same full frame resolution. The D780 will be an easy transition for any DSLR and full frame shooter. It has the iconic look and feel of a Nikon DSLR with the potential of a mirrorless camera. 

 

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.

 

Who Should Consider Purchasing the Nikon D780?

 

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.
