Some lens are spherical, some are non-spherical, some are aspherical. Difference? I assume the non & the aspherical are the same.
What is AIS or AI-S? What is HSM? What is AFS?
My lens wish list:
Sigma Super Wide Angle 14mm f/2.8 EX Aspherical HSM Autofocus
Sigma Zoom Wide Angle-Telephoto 24-70mm f/2.8 EX Aspherical DF
Nikon Zoom Telephoto AF VR Zoom Nikkor 70-200mm f/2.8D G-AFS ED-IF Autofocus Lens (Vibration Reduction) - Black
Nikon Normal AF Nikkor 50mm f/1.8D Autofocus Lens
