Cavision 0.35x Wide Angle Fish-eye Auxiliary Lens for Lenses with 58mm Filter Threads, or 52mm with Optional AR58-52 Adapter Ring.

While the Cavision 0.35x Wide Angle Fish-eye Adapter is a non-zoom-through lens accessory, it is innovatively designed for lenses with 58mm front filter threads, or alternatively, 52mm threads when used with the optional AR58-52 Adapter Ring. This high-quality auxiliary lens is capable of providing a unique fish-eye effect, expanding your field of view by a remarkable 65%. Its versatile, universal design makes it compatible with a wide range of lenses, enhancing your photographic capabilities.

Understanding the difference between Wide Angle Adapters and Wide Angle Converters is crucial. Fixed focal adapters, like this one, may lose focus when the focal length on the camera lens is altered, such as during zooming. Therefore, it's worth noting that this adapter may not be the best choice for scenarios requiring live zooms. However, it's typically possible to adjust the zoom level slightly while still maintaining focus.

When using this durable, user-friendly adapter, the standard focusing operation is replaced by the macro focus control. For mini-DV cameras lacking a macro focus control, the lens will generally retain focus from the widest angle to approximately 1/4 of the zoom range.

On the other hand, with zoom-through converters, the normal lens operation remains unaffected. Focus operations will function as before, and focus will not be compromised when the focal length is changed, i.e., during zooming. This Cavision 0.35x Wide Angle Fish-eye Adapter is an excellent tool for photographers looking to experiment with wide-angle, fish-eye effects, offering a new perspective to their work.
