The set includes 1x UV filter, 1x Polarizing Circular Filter and 1x Close-up +4 macro pre-set.
Macro preset Close Up +4
Allows you to take macro shots without special macro lenses. The principle works similarly to reading glasses, the macro preset allows the lens to get closer to a small subject.
Macro photography, or photographing small objects, can be accomplished by using special lenses or by using a variety of aids that replace the effects of macro lenses. Among the most commonly used are intermediate rings and close-up presets.
The advantages of preset lenses are minimal exposure prolongation, AF focusing capability, ease of handling and low cost. The disadvantages are a smaller magnification ratio and optical aberrations (most commonly color errors, which show up as color fringing in sharp transitions between light and shade. Achromatic (binary) lenses are used to suppress this error) and a smaller magnification ratio. And of course, they do not allow focusing at infinity.
A close-up lens is a lens inserted into the sleeve (hoop) of a photographic filter. It is most commonly fitted onto the filter thread of a lens - you need to know what diameter filter thread your lens has so you can choose a close-up preset.
UV
This thin UV filter absorbs ultraviolet rays, which often cause outdoor photos to be hazy and bland. It's thin enough to prevent vignetting and can be used on wide-angle lenses as well. It is used for color and black and white film photography and also for digital.
It also serves as a permanent lens protector.
Polarizing Circular
This thin Polarizing Filter removes unwanted reflections from non-metallic surfaces such as water, glass...
Polarizing filters are the most important filters for improving color rendition. They are color neutral and are suitable for both analog and digital photography. The polarizing filter effect is NOT achievable by any additional software modification!
- they enhance the rendering of clouds, the sky blue is richer, the colours are cleaner and brighter
- reduce haze for long distance shots
- removes glare e.g. on glass (not on metal), water surface becomes clearer.
