A7m4 is slow to transmit photos.

A7M4 is a camera model introduced by Sony, which is mainly aimed at photographers and professional photographers. The speed at which the camera transmits photos depends on many factors, including the resolution of photos, file format, transmission medium and so on. Generally speaking, if you think A7M4 is slow in transmitting photos, you can try the following methods to improve it:

1. Use a fast memory card: If you use a slow memory card, the transmission speed will be limited. Try using a faster memory card, such as UHS-II or CFexpress.

2. Choose the appropriate transmission mode: A7M4 supports multiple transmission modes, including USB, Wi-Fi and wired network transmission. You can choose the transmission mode that suits your needs and ensure a stable network connection.

3. Compressed photo file: If the photo file format you use is RAW format, consider using a compressed format (such as JPEG) to transmit photos. Because the file in RAW format is relatively large, the transmission speed will be slow.

4. Update camera firmware: Sony will continuously introduce new camera firmware versions to solve some performance problems and optimize transmission speed. Please make sure that your camera firmware is the latest version, and you can download the update from Sony official website.

If you still feel that the transmission speed is slow after trying the above methods, I suggest you contact Sony customer service, who can provide more specific help and support.
