Serounder 52mm Fisheye 52mm
Its aluminum alloy construction with anti-reflection coated glass provides a 0.35X magnification fisheye effect on standard 52mm filter thread lenses. The scratch-proof, oil-proof build and 230g weight ensure durable portability for quick attachment. Casual macro shooters would benefit most from this converter’s expanded wide-angle framing at a low cost.
