Photo Review Tech Editor Margaret Brown looks into the benefits and consequences of using focal length extenders.
Don’t discard your old lenses; adapters can enable you to use them on your latest camera, usually with worthwhile results.
Lens aperture is an important criterion in any camera’s exposure adjustments. But, for low light photographers, it is equally important in determining the choice of which lens to use.
The uses, advantages and disadvantages of shooting with longer telephoto lenses.
The main accessories for lenses are hoods, filters and adapters and all have benefits and drawbacks. Some manufacturers supply lens hoods with lenses; others offer them as options. Filters and adapters are always sold separately.
There’s a lot of misunderstanding about what constitutes a ‘macro’ lens. True macro capabilities require the lens to be capable of 1:1 or ‘life size’ reproduction. Lenses that provide a 2:1 reproduction ratio (or greater) also qualify as macro lenses but they are usually highly specialised and not widely available.
Although most lenses can be used for portraiture, fast telephoto lenses with moderately short focal lengths have long been the first choice of professional portrait photographers. Focal lengths typically considered ideal range from about 70mm to 135mm in 35mm format, with a bias in favour of the 85-105mm section.
Although just about any lens can be used for photographing landscapes, most photographers prefer using wide-angle lenses because they better encompass scenic panoramas. But that doesn’t mean they’re the only option.
The second lens in a twin-lens kit is usually a telephoto zoom lens that picks up where the range of the standard zoom lens ends. These lenses take in focal lengths that are ideal for portraiture, sports and wildlife photography.
Most people buying an interchangeable-lens camera for the first time will opt for the ‘kit’ lens bundled with the camera. When you’re buying an entry- or mid-level camera, it’s a convenient way to get a lens (or two) that suits the camera.
