Forums > Back > next PZ lens test report: Sigma AF 85mm f/1.4 HSM EX DG
#7
My guess is reaching the limitation of resolution of the lens. I.e, newer aps-c like the 7d have smaller pixels and therefore require higher resolution from the lens to maximize the sensor. Having said that I did not actually check how it 'fared' worse and presumed (perhaps incorrectly) it was a resolution issue.

This lens is very high on my "wanted" list. A bit odd that it seemed to fare worse in the APS-C tests than FF ones (?).
