The warmer colour of the Canon image works well here. I've maybe darkened it a bit too much but it seemed to look best for highlight detail this way. For both cameras, a shutter speed of 1/160th was used for the Elinchrom studio flash, but both of them strayed for this too readily when making adjustments (to the aperture setting). The Canon appears to be back focusing here, and may need a micro AF adjustment. However, it is never safe to do micro AF adjustments based on closeups; they should be done at between 30X and 50X the focal length, and zooms should be set to the short side of the centre of their range - I'll maybe calibrate this lens at 35mm focal length.
