This is the Hama Filter Clamp for 49-58cm Filter Pack 2 [5896]

Most owners of DSLR cameras and higher end video cameras will be familiar with and use filters. They are usually extremely easy to apply and remove, simply screwing on or off of the lens or each other. That's until one gets stuck. This may happen due to rusting, damage to the filter or camera lens or for other unknown reasons, but either way, they can be almost impossible to remove with your bare hands, leaving you stuck with the same filter attached to your lens indefinitely and significantly hampering your photographic efforts. Hama filter clamps (or wrenches) are a simple design that can be fitted around most filters measuring 49-58mm and provide the extra leverage that is required to remove/unstick seized filter using the handy grips to twist it from its mount. In a few quick twists your lens or filter should be free for the mounting of alternative filters and accessories.

Highlights
For easily screwing off seized filters thanks to leverage effect or for removing two filters which are too tightly screwed with each other
For filters or other screw-able lens attachments with a diameter between 49 and 58mm
