In the overall history of camera technology image stabilization is a rather recent development. Image stabilized lenses did not appear up until 1995 when Canon introduced the EF 75-300mm f/4 – 5.6 IS - the first image stabilized lens. IS or Image Stabilization is the acronym that Canon uses to refer to this technology. The technology was actually first seen on a previous lens, also made by Canon, the EF 300mm f/2.8L IS USM. This lens however did not reach the market up until 1999 which made the 75-300mm the first commercially produced image stabilized lens the world has seen.
Nikon calls this technology VR or Vibration Reduction. Other manufacturers use different other acronyms to label this technology. However, at the end of the day, they all mean the exact same thing. Though, in this case it is fair to say that all technologies are not the same. In fact all lenses are not optically stabilized either. There are some manufacturers who prefer to stabilize the sensor inside the camera rather than the lens! This happened because when image stabilization was developed digital sensors were not around and it would have meant either moving the physical film or the sensor. Canon and Nikon devised it was much easier to move the focusing elements inside the lens than moving the actual film.
Okay. Now we need to have a deeper understanding of how image stabilization works and why most professional and serious enthusiasts prefer to pay more for image stabilized lenses. Read more...
