Unlike most compact cameras, you can attach underwater converters and 45mm filters to the high-quality TG models using the CLA-T01 converter lens adapter. The FCON-T02 fisheye converter enables circular fisheye recordings without restricting the lens brightness. Simply change the zoom position of THE FCON-T02 to switch between circular fisheye and full-frame fisheye photography. It is waterproof and is therefore also suitable for unique underwater pictures. The interior of the lens is filled with nitrogen gas, which prevents internal fogging due to temperature differences. With this unique accessory you can create more dynamic pictures and through the large wide angle the beauty of the underwater world is fully accentuated.
