VIDEO
Because the Sony A7C Mark II and the A7C are so small, you frequently wish to bring them on vacations. Of course, having the ability to create stunning videos is advantageous. Fortunately, both cameras are excellent at this, but there are still disparities.
For instance, the A7C can film at a resolution of 4K30fps, which is more than sufficient for the majority of circumstances. You can film in 4K at 60 frames per second with the A7C Mark II and A7 IV, but you don’t utilize the entire sensor. Only Super35 mode, which has a 1.5x crop factor, may be used to capture 4K60p video with the A7C II or A7 IV.
However, the A7C II can capture 4K30p films from 7K oversampled video, which has the sharpest detail possible. This oversampling is marginally superior to the A7C’s, which can capture footage in 4K30p using a 6K oversampling. The A7C II or A7 IV should not be chosen only for this reason, as the difference is hardly discernible.
Another crucial factor is dynamic range, where there is just a slight difference between the three cameras. When you shoot in Slog-3, the Sony A7C offers a dynamic range of 14 stops. A dynamic range of 15 stops is slightly better on the A7C II and A7 IV.
The additional stability that the Sony A7C II and A7 IV feature, specifically the Active Mode, as Sony refers to it, is a key point to make. This method makes advantage of the camera’s gyro sensor to catch every movement in the movie. After that, you can use software to further stabilize the image.
The IBIS can make up to five stops of compensation even though the original A7C lacks this Active Mode. Additionally, the A7C II and A7 IV now include built-in stabilization that can correct for 5.5 stops, which is an improvement over previous models.
While the Sony A7C II and A7C use micro-HDMI ports, the Sony A7 IV uses a full-size HDMI port for connecting monitors. This is significantly more delicate and can break much more quickly. Something to think about. The A7 IV’s bigger body lets the heat to dissipate more evenly, so cooling is also improved.
AUTOFOCUS
Between the A7C II, A7 IV, and A7C, there are already several noticeable modifications in the sensor and video functionalities mentioned above. The autofocus will make the third key difference clear. Well, I’ll say up front that the A7C’s autofocus is truly great.
The AI component Sony installed in the A7C II is the first significant difference. This second CPU focuses solely on the camera’s deep learning functionality. This indicates that compared to the A7 IV and the A7C, the A7C II is much more accurate while focusing and can recognize a far larger number of subjects.
At least the eyes are always crisp, according to Sony, who says that the A7C Mark II and Sony A7 IV can focus up to 30% more correctly on people’s eyes. Animal eyes can also be distinguished by the A7C II and A7 IV, which is not necessarily a distinction from the A7C. The A7 IV and A7C II vary in that they can distinguish animal eyes in video mode.
The autofocus coverage of the three cameras has improved on the A7C II and A7 IV by up to one percent, which is a minor improvement to note. They cover 94% of the area, compared to 93% for the A7C.
