hi.
i purchased the new nikon 24-70 f/2.8 lens and i'm not happy with this lens at all.
first copy i bought had front focus problem at 70mm only which i couldn't solve this problem with the af fine tune future in my d300 camera.. i exchanged the lens and the second copy had some bubbles and dust inside the lens. i know it doesn't effect the photographs but i thought it should be a perfect lens if i pay over 1000 pounds.. i did have many other lenses and none of them has any dust or bubbles inside..
i then went to my local store again and exchanged the lens.
this copy has different focus problems. with the af fine tune i can set to +12 setting and i can get sharp results at 24mm, 35mm and 70mm.. but photos are out of focus again at the 50mm..
field curvature is really bad at 24mm and I can see some CA in the pictures.

I tested the lens on the tripod with the remote shutter and MLU.

...should i get a new copy? because i can see many people are very happy with this lens.
i also know some people are reported similar problems and i don't have luck with this lens at all..
or should i send it to nikon for calibration?..
but then maybe they can left some dust in the lens. am i being too paranoid?.

or should i get 14-24 f/2.8 lens and wait for QC problems to be solved with the 24-70 f/2.8..?
