Solebury Mountain Observatory


Nikon Micro-Nikkor 60mm Page

It's really astounding what this lens does for the performance of a Nikon D100 Digital Camera!

The page is currently pretty sparse, just some sample pictures. But it should give you some idea of the quality of the raw images coming from the camera. Simply spectacular!

Warning! The images on the page are quite large and will take some time to load. I suggest a broadband connection only!
