New 24-70 L II - something wrong with mine? is this normal?
« on: September 25, 2012, 10:46:34 AM »
Hi! I just bought a new 24-70 last night. At 1st I was very impressed and it seemed very sharp on all apertures. However, this morning i wanted to take a closer look and Pixel peep a little. I was shocked to find that the right edge of the frame was completely blurry from top to bottom. I took a lot of test shot at various apertures and it happened all the way from 2.8 to 22 !!!!! I dont know if im overreacting or if I should return/exchange the lens. I will post the JPEG's that i converted from raw no NO ADJUSTMENTS. Can some please help me out with this. I dont think is normal or maybe im just spoiled from using primes. Look up close on the building on the right

This one is @ 2.8

this happens from 24mm to 40mm and it gets progressively better :'( the rest of the frame is nice and sharp even the left edge

I own the version 1 but I would say that you have a bad lens.  I presume you have tested with other lenses to verify that it is not the camera?

It does look bad, but this is not the way to evaluate the lens.  Line it up perpendicular to a brick wall at a fair distance back, and then you can see a issue much better.  Then, turn it upside down and take a image of the same view.
If the bad area moves to the opposite side, get it fixed or exchange it.  If the blurry area stays in the same place, its not the lens.
