Some say that the 60mm micro is optimized for close focusing and degrades at distance. Make your own conclusions... both images shot within moments of each other on a Gitzo 1228 and Markins M10 ball head using the ML-L1 remote. Both using Nikon L37C filter. In camera sharpening normal; no other post processing. These are the original uncropped images saved in Nikon Capture 4.2 as jpg good quality.
