Extension tubes are designed to enable a lens to focus closer than its normal set minimum focusing distance. Getting closer has the effect of magnifying your subject (making it appear larger in the viewfinder and in your pictures). They are exceptionally useful for macro photography, enabling you to convert almost any lens into a macro lens at a fraction of the cost while maintaining its original optical quality. The DG extension tubes have no optics. They are mounted in between the camera body and lens to create more distance between the lens and film plane. By moving the lens father away from the film or CCD sensor in the camera, the lens is forced to focus much closer than normal. The greater the length of the extension tube, the closer the lens can focus.

The Opteka Auto Extension Tube Set contains three tubes of different length, a 13 mm, 21 mm, and 31 mm, which can be used individually or in any combination to obtain the desired magnification. Opteka's Auto Focus extension tubes are designed with all the circuitry and mechanical coupling to maintain auto focus and TTL auto exposure.

Absorbing 4 stops of light this filter helps Provide a balanced exposures and better depth-of-field control. High-Trans Titanium Filters have very high transmissive properties utilizing multicoatings and a Titanium oxide component. These filters are mounted in a light weight metal ring with a matte black anti reflective inner ring and a Titanium finnish outer ring to identify the titanium oxide componenet in the filter. The new coatings for this filter increases hardness and reduces the suceptibility to smearing.

This Item Includes: 1. UV Lens Filter 2. Circular Polarizing Filter 3. Flourescent Filter 4. Filter Pouch 5. Nwv Direct Microfiber Cleaning Cloth. Lens filters are translucent pieces of glass placed in front of a camera lens to alter or adjust the light entering the camera and more importantly to protect the camera lens. Lens filters improve photographs by giving photographers control over light and allowing them to emphasize the features of a scene that they consider most important.This filter kit is a combination of the three essential filters no photographer should be without.UV--Film and a digital CCD are more sensitive to UV light than our eyes are. This often shows up in images shot from high altitudes and long distances especially over water. This filter will remove the UV light and more importantly protect your lens from moisture, scratches, and damage. Circular Polarizer--provides color and contrast enhancement. Reflected light often shows up as a whitish glare that washes out color in an image. A polarizing filter will correct this problem creating deep blue skies. It also removes glare from non-metallic surfaces such as windows and water.FLD--provides color correction when shooting under fluorescent lighting. It will remove the greenish tint from the image, providing pleasing skin tones and true to life color renditions. Warranty:10 year manufacturer warranty. Made in Japan
