Sigma 8mm f/3.5 EX DG Circular Fisheye 8mm

58.2 Score
8mm f/3.5 Canon EF, Canon RF
Why we recommend this

Its defining characteristic is the full 180-degree circular image it projects onto full-frame sensors, creating a distinctive, frame-filling fisheye effect. The use of SLD glass and a Super Multi-Layer coating ensures strong correction of chromatic aberration and effective flare suppression for clean image quality. This lens is best for experimental photographers and astrophotographers seeking a dedicated circular fisheye perspective, not a standard rectilinear wide-angle.

Sigma Contemporary 302972 30mm

23.3 Score
30mm 16 Canon RF
Why we recommend this ▼

Its f/1.4 maximum aperture and 30mm focal length provide strong low-light capability and smooth bokeh, housed in a weather-sealed, 286g body. Fast, near-silent autofocus and the 9-blade diaphragm make it equally reliable for video and portrait work. This lens best suits APS-C mirrorless shooters seeking a compact prime for everyday photography and shallow depth-of-field portraits.
