Canon EF 100mm f/2.8 Macro USM - £440
Despite a little edge softness at f/2.8, the Canon lens does a sterling job to produce sharp images with good consistency across the frame.
Central performance is very good, with only minimal levels of fringing at all apertures, but things start to fall apart towards the edges.
Distortion is low, but it's not quite as low as on some of the others. Overall, its performance is consistent with its price tag.
Images test verdict
Sharpness is sometimes excellent, and consistent. With reasonable control over both distortion and fringing, the Canon's a good performer.
