Okay so this past weekend i purchased a nikkor 24-70mm f/2.8 lense. And as i was using it to take some homecoming photos for some highschoolers i noticed that even at various f-stops/ auto focus, even the supposed focused areas were kinda hazy and not as sharp as I had expected from this lense. I know most people will jump to the conclusion that it's most likely the user (me) and not the lense that is doing something wrong. However the background behind purchasing this lense new from samy's camera was that it was the second one I had received from them in the same day. promptly after arriving home from my first purchase, as i was mounting the lense i noticed a slight reflection (thanks to my O.C.D.) in the glass, inspected it and noticed that there was something EXTREMELY EXTREMELY small (either dust, debris, or a scratch) on the inside of the glass. brought it back to them and they finally noticed it as well. They agreed it was a defect for sure and exchanged it for me. My point is as well as the quality control by nikon may be, mishaps do occur and it has already happened to me once regarding the purchase of this lense and now i'm hesitant as to if this "hazyness" is also another defect. Here is a photo that i took with it that may serve as an example. I have used a 50mm f/1.8 on many occasions and I know how deadly the difference between focused and non-focused areas with low f-stops but imo if i can get great distinctions in focus with a 1.8 manually/automatically i do not understand why theres problems with f/2.8 unless there is yet another defect. Here's the link to the photos: OC Photography's Photos - '09 Temple City High School Homecoming | Facebook note: (1) I know the background/scenery is bad so please don't judge on that, the caption to the album will explain why if you're curious (2) sorry that i had to use a link to facebook, but i haven't had time to post onto other hosting sites nor do i have enough post counts to attach it here yet =\ (3) IT IS DEFINITELY NOT because facebook lowers the quality of the images, my proofs on my computer as identical to those in therms of "hazyness"
