AF-S NIKKOR 70-200mm f/4G ED VR VS the 70-200 2.8, according to DXOMAR website
the AF-S NIKKOR 70-200mm f/4G ED VR out performs in sharpness by 6 points, the AF-S NIKKOR 70-200mm f/4G ED VR is rated at 22, where the 2.8 version of this lense is only rated at 16. and
over all rating the 2.8 version of this lens trails the F4 version by 2 points
so the F4 version is rated better, and in sharpness blows the 2.8 version away..
So a learning lesson here, don't always look a lens as being better because it can go down to a lower number aperture, just because one lens can do 2.8 and the other only F4 doesn't always mean the 2.8 is the winner in quality and sharpness, how ever it will almost always mean more money for the 2,8 verison because people are so hyped about bluring the background, thinking a lesn that does it better then another is better, which is BS!!!! i can blur the background with the F4 as well after all it's zoom lens that goes as far as 200 mm that make sit so easy to blur the background if you have any skill in photography what so ever.. :/
the best part is the F4 is about half the price as the 2.8 version, yes you will feel happy that you got your 2.8 heavy glass and think your getting better pictures as far as sharpness, the fact is the F4 will render better sharpness even tho you paid the high price.
Also remember a lens is not always sharper then another because it can open up wider, in fact using the lens wide open your getting the bottom quality aperture of your lens, almost always most lenses get sharper the higher you set your aperture number, for instance taking a shot at f8 will probably render you better sharpness then if you took it at F2.8, now there is a limit tho, i mean the higher you go doesn't mean if you just jack the Aperture up to it's highest number your getting the highest quality, there is a sweet spot in your lens, if you go over it, your quality will start to fade..
But for the most part most lenses the lower aperture number will probably render you lower sharpness then a high fstop number..
So don't think just because a lens does a lower aperture number makes it a sharper lens.
this is not always true..
and in the case of the 70-200 the F4 vs the F2.8 the F4 wins..
and it's half the price..
