KenRockwell reviewed the Nikon 105mm f/2.8GED-IF AF-S VR Micro-Nikkor and wrote:
“I tried three samples at PMA 2006. All of them didn’t autofocus very well on my D200. They would often not get good focus, so the green focus confirmation dot in the lower left of the finder wouldn’t light, so the shutter wouldn’t release in S
mode. This is bad. My old 105 mm AF, not even D, focuses much more reliably
Pass on it and get the older 105 mm f/2.8 AF instead. That older lens sells for $700 and this new one sells for $830. I’m hoping the focus issue I saw will go away. I’ll let you know if I try it again.”
