Nikon D780
Year: 2020
Price : $ 2.200

The D780 is the result of a marked improvement in quality and performance from the D750. The sensor has 24 MP with with phase detection on the sensor and a 51-point AF system. 7 frames per second (12 fps in electronic). The EN-EL15c battery has a capacity of 2,260 shots, and the D780 also accepts EN-EL15 batteries, but these cannot be recharged in-camera. Dual UHS-II SD card slots.
First of all, I must say that the D780 is an outstanding camera, at the top of its class and very close to the more expensive D850. Before I look at the Pros and Cons I will say right away that the D750 in summary represents some good sides of mirrorless cameras and some good sides of DSLRs. The technical details are at the bottom.

Pro
1 - Very fast autofocus.
Phase detection live view autofocus. It responds immediately with precision. Since I have also tried some mirrorless cameras I would say that there is no comparison in speed and accuracy, but this is a known problem with mirrorless cameras (and not the only one).
The lever to change the focus mode is located on the lower left side

AF: auto focus
M: manual focus
Tip: By selecting AF-A the D780 automatically sets AF-S for static subjects and AF-C for moving subjects.
Tip: You can use Focus Peaking (Live View) for both movies and photos in manual focus and you will get the areas in focus in brighter color.
Rating: excellent
2 - Shutter speed
The speed of this shutter is remarkable and goes up to 1/8,000 sec (1/4,000 sec in the D750) and there is also an interesting option for those who want to shoot in the dark: the shutter speed, which you can extend in manual up to 15 minutes. There is no such option in other Nikon DSLRs and it is an interesting plus.
3 - SD slots:
For 2 cards. It is then possible to save all the settings of U1 and U2 in the SD1 card. Then you can save the file NCSET001. BIN in slot 1 (not in 2) before any repair or share the settings with other D780 users. The second card can serve as a backup:

Rating: excellent

- For sports and moving subjects: excellent
- Direct live optical finder: excellent

Cons
- No flash
- Burst speed at 12 fps with slight rolling shutter (rolling shutter effect). Solution: increase shutter speed.
- Extracting the monitor is hard and difficult. The slots are too close to the rubber eyecup.
