Lens Review
Introduction | Sigma 30mm F1.4 DC HSM A Canon lens performance | Sigma 30mm F1.4 DC HSM A Nikon lens performance | Sigma 30mm F1.4 DC HSM A Canon Versus Canon EF 40mm f/2.8 STM | Sigma 30mm F1.4 DC HSM A Nikon Versus Nikon AF-S DX Nikkor 35mm f/1.8G | Conclusion

Comparing the Canon mount model to the full-frame $249 Canon EF 40mm f/2.8 STM (the firm doesn’t have a comparable APS-C format model in its range) the Sigma is a better performer but the tiny Canon ‘pancake’ is no slouch. Sharpness is close although the Sigma is a somewhat disappointing at full aperture whereas the Canon has consistent edge to edge sharpness through the aperture range Needless to say the Sigma is (1.33 stops) ‘faster’ than the Canon, and so overall it’s an impressive result.
