Summary: Actually, there are no real disadvantages of this Olympus 60 mm macro lens to consider. This is one of the best performing micro-43 lenses on the market now. The resolution of the Olympus 60 mm macro on a 16-megapixel Olympus OM-D is higher than that of the many lenses we have tested on a camera with an APS-C sensor. Compared to the famous Olympus 50 mm macro for four-thirds, this Olympus 60 mm macro lens scores virtually the same.
Pros: Very high image quality:, Dust and splash proof, Constant body length & focus limiter
Cons: Actually none, but if you are splitting hairs: expensive and big compared to the Olympus 45 mm 1.8, which offers the same optical quality (but no macro)
