Only some of the current Sony cameras are particularly good, they have made big advances but its not across all Sony cameras. Similarly only some of Nikons use good Sony sensors.
100mm diameter lens? Are you sure you don't mean focal length? The Nikon 105mm f2.8 Macro is the only choice. Fantastic lens for astro, been using it for years, Canon do make an equivalent one. BTW the f2.8 Nikon lenses are great, pin sharp, i use 14-24 and 70-200 as well.
