Vibration Reduction

Vibration Reduction atau VR merupakan fasilitas dari varian lensa kamera yang berfungsi mengurangi getaran karena kurang kuatnya tangan pada saat mengambil gambar. Istilah ini digunakan pada lensa-lensa dari serial kamera bermerek Nikon. Canon menggunakan istilah Image Stabilizer (IS) yang fungsinya sama dengan VR dan juga Sigma menggunakan istilah Optical Stabilizer (OS). Ketiga istilah ini pada dasarnya bekerja dengan cara yang sama, yaitu menggunakan grup tambahan di tubuh lensa yang berfungsi untuk menyeimbangkan bidikan lensa dengan cara menggerakkan grup ini ke arah yang berlawanan dari getaran tangan kita. Sistem penyeimbang di tubuh lensa ini lebih superior dari sistem penyeimbang yang terdapat di sensor kamera seperti Sony Alpha, dimana hasil yang stabil bisa dilihat langsung di optical viewfinder.

Sistem ini terus dikembangkan dimana pada saat ini (Desember 2006), tehnologi yang terakhir bisa memberikan total 4-stop lebih lambat daripada jika kamera dipegang oleh tangan, seperti di lensa Canon EF 70-200mm f/4 IS USM.

Contoh: Untuk lensa di atas, dengan mengikuti pedoman standar panjang fokal / detik, jika lensa tersebut di-zoom ke 200mm dan dipegang secara handheld, maka pedoman Shutter Speed yang aman adalah 1/200 detik. Dengan tehnologi ini, maka lensa yang sama bisa dipakai hanya dalam 1/12 detik.
