When I tried this lens accessory for my Olympus camera I was really impressed with how simple it was to use and how much it enhanced my photography .The compatibility with Panasonic cameras is also a great bonus. The aperture adjustment is smooth and precise, making it easy to achieve the exact look I`m going for. The only downside is that IT adds a bit of weight to my equipment, but it's worth it for the results. Overall, a great investment for any electronics enthusiast looking to up their photography game..
