Hi,
I have read somewhere that lenses are optimized for distance. Like, i have read that Nikon AF-D 180 2.8 is not as good at infinity as it is for nearer distances, perhaps because they chose to design it for photojournalists. Macro lenses are also a case in point, where quite often they are better performers at macro distances.
What if someone wants to purchase a lens like 180 2.8, expecting to shoot landscapes with it, or a Sigma 150 2.8, expecting to use it as a telephoto over and above its macro function. If a particular lens is not optimized for something, how do you know that before buying it?
It will help if i know that lens A is better at infinity than lens B, though both have same focal length.
regards,
anurag
