ya no the 18-55 isn't to to bad a lens the 18-105 that comes with the d90 doesn't even compare to the 18-55 really, this lens is notoriously soft of you look into it you will read much about that problem specifically.
I never said the 18-105 was sharp, just generally not that bad.
from reviews i have read mot of them where saying the 18-200 was one of Nikon's sharper lenses they have
Not. Even. Close.
if that were true, everyone would shoot with 18-200's, but..
I guess that means at 200mm f/5.6 it's about as good as the 200mm f/2 is at 5.6.
Or what about the 14-24 for the wide end? nah it's junk, the 18-200 is better.
Screw any of the PC or macro lenses, they don't zoom.
Who needs wide apertures anyway? the 35 f/1.8, 50 1.4, 85 1.8/4, 105 f/2, i'll just shoot at ISO 6400 and f/5.6 the whole time on my 18-200 anyway since it zooms.
the 180mm doesn't have af-s.
the 70-200 won't go to 18mm.
the 18-200 is pretty much just as sharp as any of the exotic telephoto lenses, i'll just put a TC on it, does the same thing.
Sorry for the sarcasm, but unless you've been reading the 18-200 review from kenrockwell, most people say the same thing, it's a jack of all trades, but a master of none. go inside and it's not really even a jack anymore, more like a 6 or 7. it's a good lens, but not great. it's not revolutionary anymore like it was six years ago, and it's just a really expensive lens for what you're getting as far as image quality and build. if you're looking for
quality i highly suggest you look elsewhere besides 11x superzooms, because aside from the extra 95mm on the long end, focus scales, metal mount, and
slightly better sharpness, what does the 18-200 give you over the 18-105...probably not a whole lot, and i bet not $765 a whole lot either.
There's also alot more to lenses than sharpness. there's qualities of how they project and render that give images character aside from surgical sharpness. This is why I have a 50mm as my midrange on my SLR and i'm going to be moving my SLR system to fast prime lenses and away from the zooms. They all have a unique character, and when they need to be surgically sharp, they can be. lenses like Nikon's 24-70 have no character.
it's hard to explain..but it's a similar reason why alot of people shoot leica.
