The insidiousness of “video cameras”: the mileage is 5,000 frames, and the matrix has worked for 2,000 hours

With the development of video shooting on hybrid mirrorless cameras (Sony A7S III, Panasonic GH5/GH6, Fujifilm X-T4, Canon R6), a special class of used cameras. The seller displays the carcass with a proud note:“Shutter travel is only 3,500 frames! New condition!”. However, when turned on during long-term shooting, the matrix overheats after 5 minutes.

As a service engineer, I declare: **for a video camera, a short shutter travel DOES NOT GUARANTEE the “freshness” of the matrix!**

3 Main risks when buying a used video camera

1. Pixel burnout by lasers at concerts and clubs:if the videographer filmed in clubs with a laser show, a direct laser beam burns tracks on the matrix. Incurable glowing streaks appear in the video and hot spots.
2. Overheating and degradation of processor thermal paste:regular shooting 4K 60fps in the heat speeds up aging of sensor trim elements.
3. Wear of the rotary display cable:Constantly rotating the screen leads to rubbing multi-core loop.

How to check the camera from under video recording?

• Check the mileage on our service: if the mileage is low (up to 10k), but the HDMI socket is loose, and on the bottom scratches from the video rig - the carcass was actively filming video.
• Record 4K video for 15-20 minutes during your meeting and check for heat and hot pixels.
