Camera Lenses Explained: how to get sharp photos using telephoto lenses
Using telephoto lenses with image stabilisers
Many camera and lens manufacturers have developed systems that enable you to get sharp results with slow shutter speeds. Most current Sony, Pentax and Olympus DSLRs use an in-camera system, so it’s available whichever lens you use.
Canon, Nikon, Sigma, and Tamron use lens-based systems, which tend to be better than the in-camera ones.
Look out for lenses with the following abbreviations: IS (Image Stabilizer), VR (Vibration Reduction), OS (Optical Stabilizer), and VC (Vibration Compensation).
With a little practice these systems enable you to shoot with shutter speeds well below those you would normally use when hand-holding the camera.
Shooting from a distance using a telephoto lens makes all the subjects in the frame appear much closer to each other than if you’d used a shorter focal-length lens from a nearer viewpoint.
It’s the distance that you shoot from rather than the focal length that causes the ‘compressed perspective’ effect.
If you don’t have a long lens you can get the same effect by simply cropping in on an image shot at a shorter focal length at the same distance as you would if shooting with a telephoto.
