8 out of 10 points and recommendedvery sharp along the whole zoom range, no distortion, no CA, lock to prevent zoom creepZoom ring movement too long, requires a "big" twist of the wrist, no focus limit switch, aperture is small
I have been using this lens for 3 weeks.reviewed August 8th, 2015
It has surprisingly good IQ.
It's not heavy for the class and easy to handle.
I miss a focus limit switch to keep the lens from hunting from close focus to infinity.
I missed some shots because of this.
Also the zoom ring requires quite a long twist of the arm which is almost impossible to use in the field when trying to zoom from 200 to 500 mm or back.
If it's important to anyone the lens has a"wow factor" because it's so long and massive looking. Especially with hood on.
10 out of 10 points and recommendedsharp across the range, no CA, light, cheap, great aperturenone
This lens has served me as my walk around lens for quite sometime.reviewed July 12th, 2015
It's so sharp that I do not need a larger zoom.
I simply crop the part of the image I want to enlarge. No one saw the difference so far.
In addition it's very small and light considering the optics quality and big aperture.
5 out of 10 points and not recommendedgood zoom range, build quality, constant F4 apertureheavy, zoom creep and no lock, back focus issue, expensive
I have been using this lens on a crop camera for over 2 years.reviewed June 14th, 2015 (purchased for $1,600)
With the exception of the zoom creep and weight at first I really enjoyed the lens.
But lately I have been having serious back focus issues which were not fixed in 2 labs.
The lens also has relatively high CA.
In addition the lens was very expensive when I bought it.
Now the price dropped by 30% to about 1200$.
I only use it now for landscape photography were the focus problems are not visible.
My last hope is the official Nikon dealer can fix it.
But even if he does. it's too expensive to have such problems.
The lens came back from the lab.
The price to fix the lens is 450$!!!
The "optical axis' (freely translated from Hebrew)needs to be fixed.
In plain English this means the lens needs to be taken apart and rebuilt.
