hi All,
Has anyone tried
these http://www.iceinspace.com.au/forum/d...9Af0J5EwgAOw== nikon FX lenses, in particular the 135mm and 80-200mm focal lengths. Would be used with stl11000 camera.
Is there really a notable difference between prime and variable focal length lenses in term of image quality when used in astrophotography?
If using variable focal lengths, is a change in focal length a problem during longh exposures? (may have to tape up)
What does the AI stand for in the lense description.
Any alternative suggestions welcomed also.
Josh
