I.O.S. and Nikons V.R. image stabilisation are so amazing and one exceptional advance over the old analogue film camera,s. I have demonstrated on Flicker the power of my recently aquired Nikon P900 with 24 to 2000mm (35mm equiv.) Lens. The images shown to demonstrate a photo taken at 2000mm optical and 4000mm digital are both hand held–by me–and I will not see my 36th birthday again. But no credit to me, more so made possible by the truly amazing image stabilisation. No gimmick, this truly works. Nikon best describe their V.R system as vibration reduction with an angular velocity sensor and image sensor motion vector information for vibration absorption. Now I just quote without understanding this any more than–why my dog always know its time for a trot down the garden as I am about to eat my meal. We recall from the dark days the importance of keeping the lens steady to avoid camera shake. 2000mm would have been impossible. I just cannot wait to see what is developed in fifty years time.
Image stabilisation has come a long way over the years. I’ don’t think you need to buy fast (f2.8), bulky, heavy, expensive lenses when you can buy a more more compact and lighter lens with excellent stablisation. I’ve seem your examples on Flickr and they clearly demonstrate how good it is.
