I was debating whether I should post this here or in the film photography forum, as the lens in question was made for film SLRs, but I thought since I only shoot with digital cameras I might as well post here and see what happens.
So, I recently learned about the legendary Nikkor 105mm f/2.5 Ai/Ai-s lens (The lens used by Steve McCurry to photograph the famous Afghan Girl portrait featured on the cover of NatGeo.) This lens has been praised for it's optical quality and has been found to be an excellent astrophotography lens. Now, I was and still am considering this as my next lens purchase, but while looking at Ken Rockwell's Nikon 105mm FX Corner Sharpness Comparison I noticed that the cheap Series E lens seemed to be quite good in the corners, which led me to suspect that it may be a cheaper astrophotography alternative to the more expensive 105/2.5 lens. But of course Ken's pictures are of trees and not stars, and I could not find any examples of this lens being used for astrophotography.
So if anyone reading this has used the Nikon 100mm f/2.8 Series E lens for astrophotography, I'd like to hear your results and maybe even see some images produced with the lens if possible.
