>>4317654An earlier, handheld test pic. I didn't see any mention of this in reviews, but wide open at f2.8 there is longitudinal ca. I took the same pic at f5.6 and it was very faint by then. This shows it clearly because it's high contrast and the dof is a couple of mm wide and it's red in front, green in back. I actually may not have noticed it otherwise. On regular objects you can faintly make it out in the bright white highlights.
