This advanced system ensures fast and accurate focus, even in challenging lighting conditions. The A7 IV’s real-time eye autofocus now includes birds in addition to humans and animals, making it a strong contender for wildlife photography.

Focus Mapping and Touch Tracking

The A7 IV introduces focus mapping, allowing photographers to visualize depth of field for more precise focus control.

While the Sony A7 IV is a feature-packed and versatile camera, it does have some cons and known issues that users should be aware of:

  1. Rolling Shutter: The A7 IV, like many mirrorless cameras, is prone to rolling shutter issues during fast movement or panning in video mode. This can result in distorted images, particularly when filming at lower frame rates.
  2. Menu System: Although the A7 IV has a more user-friendly interface compared to its predecessor, some users still find the menu system to be complex and challenging to navigate.
  3. Limited Articulating Screen: The A7 IV’s variable-angle touch LCD screen is an improvement over the A7 III’s tilting screen; however, it does not fully articulate, which can be limiting for some shooting scenarios, such as vlogging or selfies.
  4. Battery Life: While the A7 IV’s battery life is improved compared to previous models, it may still be insufficient for extended shooting sessions, particularly when using power-hungry features like continuous autofocus or shooting in high-resolution video modes.
  5. Price: The Sony A7 IV’s price point may be a barrier for some users, particularly beginners or hobbyists who are considering upgrading from the A7 III or other entry-level cameras.
  6. No Full-Size HDMI Port: The A7 IV uses a micro HDMI port instead of a full-size HDMI port, which can be less durable and prone to disconnection, especially when using an external monitor during video shooting.
  7. Overheating: Although rare, some users have reported instances of the A7 IV overheating during extended video recording sessions, particularly in warm environments or when shooting in high-resolution video modes.

It is essential to weigh the cons and known issues against the camera’s numerous benefits and advanced features when considering the Sony A7 IV as a potential investment.
