As we’ve seen with other makes the Sigma 35mm (54mm equivalent) f/1.4 DG HSM A is the best performing lens of its type.

Not only is very well corrected but it also achieves the highest peak sharpness score out of all those tested. In second place is the highly regarded Pentax smc DA* 55mm (85mm equivalent) f1.4 SDM, another well corrected model though with lower sharpness. That’s bettered by the smc DA 50mm (77mm equivalent) f1.8 version in sharpness, but it’s negligible in real world terms, but’s a good choice if on a budget.
