• A simple and convenient way to increase magnificationgive your photographs a more professional look
• Helps to reduce photons into your camera
• Camera len filter fits SLR camera / digital camera / camcorder DV with a 55mm diameter lens
• Metal and optical glass with rotating frame female thread on top to allow use with other filters or hoods
• This is an original product
• Camera lens is brand new in box with crystal filter case
• Size: 55 mm / 2.17 in (Dia.)

Details:

• The closeup filter is available individually in various magnifications, namely +4 diopter. High quality closeup optics is used in the manufacture of the various closeup filters to ensure that closeup photographs taken with the closeup filters are crystal clear and sharp. In addition, all zoom lenses mounted with closeup filters are able to stay in focus without distance restriction and therefore highly recommended for macro photography

• A Close-Up filter can be used to give you a magnification strength of +4. Use as an alternative to a macro lens

• Design and produced using high definition optical glass, MASS macro lenses provide high level of image clarity with superior sharpness and maximum light transmission on objects details such as flowers, jewellery, coins or small items
• The easy-to-use solution for getting extra close! This +4 macro adapter that lets you move in as close with 55mm lens. Just screw onto lens like a filter and take great close-ups. Each close up lens maintains resolution and picture clarity while magnifying image size. Use the lenses individually or in combination. Ideal for cataloging small items and focusing in on details of coins, flowers, jewelry, insects, papers, small collectibles or anything small that requires up-close detail as well as industrial photos of miniaturized components, medical and dental laboratory work and other scientific photography

What's the Camera Lens Filters:

• Camera lens filters still have many uses in digital photography, and should be an important part of any photographer's camera bag. These can include polarizing filters to reduce glare and improve saturation, or simple +4 filters to provide extra protection for the front of your lens

Close-Up Camera Effect Glass Lens Filter:

• This close-up lens allow you to take macro pictures covering a subject field with the area of half a postcard
• Cameras fitted with normal lenses do not permit us to move closer than a certain minimum distance from the object being photographed. The Close-Up lens, which is simply mounted in the front of our normal taking lens, permits the taking of close-ups and also makes possible the photography of details which would be quite impossible without using the Close-Up lens
• It doesn't block any light, so they only alter the reproduction ratio and greatly increase the working range of standard and telephoto lenses. For reasons of quality, stopping down to at least f/8 is recommended

Usage:

• Smoothing water movement in waterfalls, rivers, oceans, etc.
• Achieving a shallower depth of field in very bright light
• Reducing diffraction (which reduces sharpness) by enabling a larger aperture
• Making moving objects less apparent or not visible (such as people or cars)
• Introducing blur to convey motion with moving subjects
• photo with a smoothed water effect from a long exposure
• However, only use ND filters when absolutely necessary because they effectively discard light-which could otherwise be used to enable a shorter shutter speed (to freeze action), a smaller aperture (for depth of field) or a lower ISO setting (to reduce image noise). Additionally, some ND filters can add a very slight color cast to the image
• Generally no more than a few f-stops is need for most waterfall scenarios, so most photographers just keep one or two different ND filter amounts on hand. Extreme light reduction can enable very long exposures even during broad daylight

Problems with Lens Filters:

• Filters should only be used when necessary because they can also adversely affect the image. Since they effectively introduce an additional piece of glass between your camera's sensor and the subject, they have the potential to reduce image quality. This usually comes in the form of either a slight color tint, a reduction in local or overall image contrast, or ghosting and increased lens flare caused by light inadvertently reflecting off the inside of the filter
• Filters may also introduce physical vignetting (light fall-off or blackening at the edges of the image) if their opaque edge gets in the way of light entering the lens (right example). This was created by stacking a polarizing filter on top of a UV filter while also using a wide angle lens-causing the edges of the outermost filter to get in the way of the image. Stacking filters therefore has the potential to make all of the above problems much worse

Note on Choosing a Filter Size for a Camera Lens:

• Lens filters generally come in two varieties: screw-on and front filters. Front filters are more flexible because they can be used on virtually any lens diameter, however these may also be more cumbersome to use since they may need to be held in front of the lens. On the other hand, filter holder kits are available that can improve this process. Screw-on filters can provide an air-tight seal when needed for protection, and cannot accidentally move relative to the lens during composure. The main disadvantage is that a given screw-on filter will only work with a specific lens size
• The size of a screw-on filter is expressed in terms of its diameter, which corresponds to the diameter usually listed on the top or front of your camera lens. This diameter is listed in millimeters and usually ranges from about 46 to 82 mm for digital SLR cameras. Step-up or step-down adapters can enable a given filter size to be used on a lens with a smaller or larger diameter, respectively. However, step-down filter adapters may introduce substantial vignetting (since the filter may block light at the edges of the lens), whereas step-up adapters mean that your filter is much larger (and potentially more cumbersome) than is required
• The height of the filter edges may also be important. Ultra-thin and other special filters are designed so that they can be used on wide angle lenses without vignetting
