This Cavision 0.35X Wide Angle Fish-eye Adapter (non-zoom-through) is designed for lenses with 58mm front filter threads (or 52mm, with optional AR58-52 Adapter Ring). It provides a unique fish-eye effect with a 65% wider angle of view. It features a universal design for use with a variety of different lenses. What is the differences between Wide Angle Adapters and Wide Angle Converters? Fixed focal adapters lose focus when the focal length on the camera lens is changed (i.e. zooming). For this reason the adapter is not recommended when live zooms are necessary. Note: Typically it is possible to change the zoom level a small amount while still retaining focus. When using an adapter, the normal focusing operation does not function. It is necessary to use the macro focus control instead. For mini-DV cameras that do not have a macro focus control, the lens will typically retain focus from the widest angle to approximately 1/4 of the zoom range. With zoom-through converters, normal lens operation is not affected. Focus operations will work the same as before and focus will not be affected when the focal length is changed (i.e. zooming)

For Sale is a New-In-The-Box Hoya HMC Circular Polarizing Filter and HMC UV (Haze) Filter with a 77mm threaded base, Filter Pack By Op/Tech and a Cleaning Kit. The Circular Polarizing Filter (CPL) is needed on virtually all cameras that utilize Auto Focus and/or Automatic Exposure. The CPL filter is a regular Polarizer with an added rear filter, a 1/4 Wave Retarder, that turns the Polarized light back into "normal" light so that your camera's focusing and exposure systems can adjust correctly. To use, simply rotate the front filter ring (there are 2 parts - a front and rear ring) until the optimal effect is obtained. NOTE: The Circular Polarizer can be used on ALL cameras, but the regular (linear) polarizer cannot; so, if you are unsure, always use a Circular Polarizer. The UV (Haze) filters are wise initial investments, they help protect your valuable investment from dust and scratches. If desired it can be left on the lens at all times for protection. Haze filters provide additional benefits of correction for Ultraviolet (UV) light which often makes outdoor photographs hazy and indistinct for color as well as black and white photos. Ultraviolet filters allow you to correct for the UV effect to varying degrees. The UV-Haze filter is helpful when photographing mountain and marine scenes, where increased haze threatens to make your photographs indistinct in color and clarity. The FILTER PACK by Op/Tech USA offers a secure system for carrying extra filters. The easy-access neoprene case attaches with a snap hook so that it can be attached conveniently wherever its needed. The protective pockets are lined with a micro fiber suede which reduces lint as well as streamlines the design. This is an ideal accessory for the avid photographer on the go!
