Image Quality
The 37mm 0.25X Super Fisheye Lens provides a super fisheye effect that is suitable for capturing wide-angle shots with a unique perspective.

While it may not have the same level of universal compatibility as the fisheye lens, its autofocusing capabilities and wide-angle perspective make it ideal for landscape and architectural photography.
Ease of Use

However, the VILTROX 28mm F4.5 excels in user-friendliness with its efficient autofocus system, allowing for quick and effortless shooting without complicated setups. This feature can significantly benefit those who prefer spontaneous photography. While both lenses offer ease of use, the VILTROX’s autofocus may give it an edge for dynamic shooting situations.
