Opteka 58mm Screw-in Collapsible Rubber Lens Hood / Shade

Opteka rubber lens hoods are primarily designed to prevent unwanted stray light from entering the lens by extending and shading the end of the lens. In addition, since the end of the lens is extended you also get the added benefit of some extra protection from accidental impact.




Opteka HD² 58mm R72 720nm Infrared X-Ray IR Filter

Opteka specializes in manufacturing special optical devices for the past several years, would like to take this opportunity to introduce a newly developed product called the "HD² Infrared X-Ray Effect See-Through Multi-Coated Filter". This filter makes it possible for you to see images that are normally invisible to the human eye. It sounds like science-fiction but it isn't; this fantastic new product has been developed using the most highly advanced optical technologies available. This filter will filter out 99% of light seen by the naked eye only allowing infrared light through so that technically the naked eye can see 100% black when the filter is in place. Multi-coating prevents light reflection, ghost light...etc, making images clearer and sharper. On your digital camcorder, turn the "Nightshot" function on - the naked eye cannot pick up the high contrast black, so with the infrared filter and Nightshot combination, for example, it will help you see in the images provided, that we 'accidentally' spilt some permanent ink on this document and the text is now impossible to read. However, when we attached the filter to our Sony 'TR250PK' camcorder, the writing is clearly legible through the ink - thus the x-ray effect! You will be amazed with the power if you take the time to experiment and experience its capabilities for yourself. If you already have a digital camcorder with the Nightshot feature and are interested in experimenting with the X-Ray effect, this is by far the least expensive method, giving you the results you are looking for. Just screw on the filter, switch on the 'Night' feature, and you are ready to go!


Tamron AF 28-300mm f/3.5-6.3 XR Di LD VC (Vibration Compensation) Aspherical (IF) Macro Zoom Lens for Canon Digital SLR Cameras

The Tamron 28-300mm f/3.5-6.3 XR Di VC LD Aspherical IF Macro Lens is now equipped with a Vibration Compensation (VC) mechanism. This lens is ultra-compact and light-weight, with a constant minimum focus distance of 1.6' (0.5 m) and a high maximum magnification of 1:3. The remarkable achievements are brought about through XR (extra refractive index) glass and efficient use of aspherical lenses. The ideal "all-in-one" zoom lens, for indoor and outdoor use.

The VC mechanism helps prevent camera shake blur that may occur at slower shutter speeds. Developed by Tamron, VC features a triaxial configuration using three pairs of driving coils and slide balls around the compensator group of the lens' optical system. Since the compensator lenses are supported with rolling friction of the balls, the response performance is enhanced and the construction is simple, which results in the compactness of the lens. As a result, dimensional increases are confined to a mere 0.7" (17.8mm) in overall length and about 5mm in diameter.

Di (Digitally Integrated) design is the designation that Tamron uses for lenses that feature the improved optical design that meets the performance characteristics of digital SLR cameras, as well as film cameras. When used with APS-C size (standard) digital SLR cameras, the lens provides an angle of view equivalent to approximately 43-465mm, covering the standard to ultra telephoto range with no sacrifice of quality or aperture range.

Features:

The lens incorporates a highly accurate gyro sensor for detecting hand-shake, which, combined with a 32-bit RISC CPU, offers comfortable anti-vibration effects. The optical system uses a number of lens elements made from special optical glass materials including XR (high refraction index) glass elements, GM (glass-molded) elements, hybrid aspherical elements, LD (low dispersion) glass elements to compensate for on-axis and lateral chromatic aberrations and AD (anomalous dispersion) glass el
