Same long focal length - pick aperture or AF-S?
Of course, if money is not an issue, one may want large aperture and AF-S. If you have to pick one, do you go for large aperture or AF-S?
We have seen a lot of discussions on how to determine sharpness. How does one go about determine AF speed?
BTW, thank you for participating in a discussion nicely, w/o using negative languages.
