Fujifilm has issued an official statement regarding the overheating problem of Fujifilm X100V. They say:
When the X100V is used in a continuous manner (such as with continuous video shooting) or when used in a high temperature environment or direct sun light, a user may feel the grip become noticeably hot, due to heat generation within the camera’s electric circuit board and battery.
If you get the overheating warning please contact your local Fujifilm support and ask for a fix.
Fujifilm X100V priced at $1399. Check availability at B&H Photo / Amazon / Adorama. See below for the official Fujifilm statement.
Notice Regarding Continuous Use of Fujifilm X100
To our valued customers
Thank you very much for purchasing and using our products.
When the X100V is used in a continuous manner (such as with continuous video shooting) or when used in a high temperature environment or direct sun light, a user may feel the grip become noticeably hot, due to heat generation within the camera’s electric circuit board and battery. It is important to note that this heat will not generally affect the camera’s performance until the camera shuts off as described below. However, the emulating heat may cause skin irritation and may ultimately be uncomfortable for the user.
When the camera’s temperature increases in this manner, a yellow warning icon first appears on the LCD screen. If the temperature increases further the red warning icon will appear and shortly thereafter, the camera will turn off automatically.
In cases where the X100V shuts down automatically, we would recommend that you permit the camera to cool down before further use. In situations where the use environment is particularly hot or where the user has blood circulation or sensitive skin issues, we would recommend use of a tripod or a gimbal for periods of continuous shooting. As noted above, the camera will shut off in the event of a significant temperature increase.
You can rest assured that Fujifilm is absolutely committed to quality and service excellence, with respect to the X100V, and with respect to all other FUJIFILM products.
