I can never find enough dedicated threads for lenses when I am researching an upcoming purchase, so I wanted to get a thread started with my initial impressions in which I can update as I go along in hopes that it helps someone out in the future who is looking for this lens. I received my Nikon 24-70mm f/2.8 a few days ago and so far I absolutely love this lens. I haven't had a chance to shoot with it too much yet but from what I have done thus far, it's very sharp even wide open at f/2.8. (Low light inside the house). I expect it to be even sharper in better lighting and when I can stop it down to it's "sweet spot." Initial impressions on build quality: Built like a rock. It's a solid chunk of metal and definitely does not disappoint. It makes my 18-200 feel like a little plastic toy. It is a bit on the heavy side though, which may be an issue for some. My D300 is dwarfed by this lens unless I put the grip on I will continue to update this thread as I get more use with the lens, as well as post test shots Here are a few shots I took today when I was bored. Gives you an idea of it's size and build quality: Size: From left to right- 24-70mm, 18-200mm, 12-24mm. Shot these with my little 35mm f/1.8 since the 24-70 was in the shots.
