The influence of studio light and synchronizers on the load of the shutter system
Studio specifics: Why do “studio” carcasses last longer?
Advertisements for the sale of used equipment often indicate: *“The camera was only used in a photo studio at a shutter speed of 1/160 sec. studio light"*. In the workshop, we confirm: in studio bodies, the wear on the shutter actually occurs much more softer!
Why does working with flashes spare the shutter mechanics?
1. Working at shutter speeds X-Sync (1/160 - 1/250 sec)
During standard photography in a photo studio, the shutter operates at shutter speeds no shorter than **1/250 second**. At this speed the first curtain completely opens the frame, and the second begins to move only after the flash pulse.
- The curtains move with comfortable acceleration without the extreme dynamic shocks associated with short shutter speed 1/8000 sec.
- The brake damper experiences 2 times less load!
2. Danger of High Speed Sync (HSS/Auto FP)
If you go outside from the studio and turn on the **HSS (High-Speed Sync)** mode at shutter speeds of 1/4000–1/8000 sec, the flash emits a series of high-frequency micropulses, and the shutter forms a narrow gap between the first and second curtains. This is where mechanical wear returns to maximum values.
Gate Load Table for Various Scenarios
| Shooting scenario | Shutter speed and mode | Shutter Curtain Load |
|---|---|---|
| Classic photo studio | 1/160 – 1/200 s (X-Sync) | Minimum (Gentle kinematics) |
| Street photography with flash | 1/4000 – 1/8000 s (Auto FP HSS) | High (Extreme overclocked curtain) |
