  1. <p>Saw this article titled, "31 Photographs That Will Show You The Future Of Photography." Of course I was thrilled to get a peek into the future... I don't get it. Maybe a bad prediction? Remember, we were all supposed to be making only video calls by the late 1960's...<br> http://www.huffingtonpost.com/2015/01/01/young-photographers-photo_n_6391900.html</p> <p> </p>
  2. <p>I'm waiting for the Nikon D7400 to come out. I hear it has a cell phone function...</p>
  3. <p>Chiming in with somewhat useless knowledge of the kind that that rattles around in my brain: It's a millipede because there are two legs per body segment, as opposed to one leg per body segment in centipedes. I've never seen millipedes in the wild, however I've found them lurking in dark corners in every garage of every house I ever owned...</p>
  4. <p>I use D7000 extensively for bird shots and I also own the 70-300mm VR lens, however I don't use it for this purpose. I found the 300mm lens to be too short for most situations, particularly in wetlands where the subject distance can be extreme. Just some musings on sharpness that relate to this thread and your use of a 300mm lens that might be helpful: I shoot my Sigma 50-500mm exclusively between f9 and f13 in manual mode for two reasons. First, the depth of field for extreme telephoto shots is very thin and I want the entire bird to be in focus, and secondly that's where the Sigma lens has proven to be sharpest in testing. There's a balance point between depth of field and dispersion for every lens and this is where my Sigma performs best. Last observation is that I almost always shoot at 1/750th shutter speed because even the largest birds (with slow moving wings) will show more motion blur at the wingtips than I want if I use a slower shutter speed. The trade off here, is that I have to bump ISO (letting auto-ISO set it) to contend with a smaller aperture and higher shutter speed, and I monitor it on my D7000 to make sure I am not exceeding ISO 1200 or so, where I'm happy with the resulting shot. Regardless of your ultimate lens decision, I hope my version of the gospel here is of some help to you for getting the sharpest pictures. There are representative shots of this technique in my nature folder, and a few that violate my own rules as well.</p>
