Close-up Filters
A close-up filter works like a magnifying glass and allows the photographer to take a macro picture with a standard lens.
A close-up filter is usually specified in terms of "diopters," which is a measure of their magnifying power. Higher numbers yield more relative magnification on a given lens, but image quality also tends to decrease correspondingly.
A close-up lens, or close-up filter, is basically a magnifying glass that attaches to the front of your camera lens. Close up filters have ranging powers allowing you to get in close to varying extents.
The cheapest way to get macro shots is to buy a close-up filter to screw onto the front of your lens. They are designed to allow closer focus, and they come in various strengths, such as +2 and +4.
Sure it’ll get you close, likely to within 1:3 magnification (that’s 1/3 life-size on the film or sensor) but technically, true macro is considered 1:1 magnification—life-sized--or higher. ) Close-up filters are a less expensive ...
Other important accessories I own are: set of extension tubes (could not live without them), polarizing, ND graduated, 81B, and +3 close-up filters, flash bracket, ...
8 lens fitted with a Canon 500D close-up filter to take the photos. The close-up filter got me close enough to the flowers to fill the frame and the fast maximum aperture of the lens let me hand-hold the camera at relatively low ISOs at 1/160 second.
It's true the camera is not really built for macro work but if you get the lens hood you can attach a close-up filter.
If you take close-ups only occasionally, a simple set of screw-on close-up filters will provide an inexpensive solution. For more serious work, a macro lens or a zoom with a macro feature offers superior quality.
Macro lenses can be especially useful when photographing small details, but you can also rely on inexpensive extension tubes or front-mounting close-up filters.
If you don't have such a lens, SLR users can consider getting a set of close-up filters which attach to your lens like regular filters, but provide magnification that allows you to get very close to your subject.
Her lenses includes a 12-24mm, 28-135mm and 100-400mm; she also takes along a 2x teleconverter. "This gives me a working range of 12mm to 80mm," Waidhofer says. For her macro work, she uses an extension tube and a close-up filter rather than take a ...
