Today, technology allows us to minimize camera vibrations (through sensor displacement or lens optical element moves, depending on the brand you use). But there is nothing better than avoid vibrations from the beginning. Camera Technica did a thorough comparative test observing directly the vibration induced by various shutter triggers:
- Normal: Shutter pressed by the photographer’s digit
- Remote shutter
- Remote shutter and mirror lockup enabled
Conclusion: Do like all the best landscape photographers obsessed with the finer details: Use a tripod, lock the mirror up before shooting and use a remote shutter (and beware of the wind, too).
