Get Canon 85mm f/1.4L IS at B&H Photo.
This series looks for contrast (overall and micro contrast) but also for secondary longitudinal chromatic aberration, and any hints of focus shift.
Lens weaknesses pop out like a sore thumb with a subject and lighting like this, so I like shooting such a scene to establish baseline performance. The 85/1.4L IS is a strong performer, but it has one weakness.
Includes images at sizes up to full camera resolution from f/1.4 through f/1, and crops also.
