| p.1 #3 · 300 2.8 optical differences? |
Has anyone directly compared image quality at 2.8 for early versions (pre AF-I including manual focus) to AF-S versions on higher resolution bodies such as the D800?
Yes, I still have a few of those lenses
The optical formula of this series changed basically 2 times
The AiS/AF had an 8/6 lens structure,
the AFI 11/9,
since the AFS type I the lens is a 11/8, enhanced over time with new coating, etc ...
At f2.8 the difference between the AF and AFS is visible unless you downsize the final image considerable. The biggest difference is in night photography, where the AF produces more pronouced halo than the more modern heir.
As allways, it depens if you want to spend the $ on the new lens. Is it better? Yes it is. Does it matter? That depends more on you, less on the lens ...
