  • Yes, you said it better than I did.
  • Replied in AF fine tune?
    Thanks, Phillip.  I did actually fine tune the lens (at 80 mm, using the central spot on a distant target, with optimal result = 0).  I don't really want to change that to take the corners into ...
  • I agree viewing NEFs on my own computer screen is even more informative, but I think the JPEGs give a pretty good idea of what's going on, and it's easier for me to post the images this way.  (The ...
  • Just for fun -- and again, I'm only doing this to see how sharp the lens is focused at infinity but I'm not planning to use it as a landscape lens -- I repeated a series of shots on a different ...
  • Glad to do it. I was never able to get results as sharp in the center as shown here at 80mm with my copy of the 24-120 at 120mm on my D750 (despite using LV or regular AF with focus tuning). I'm ...
  • Here are examples.  Shot NEF, autofocused at infinity on central focus spot (i.e., no refocusing in corner for corner crops), camera on tripod, VR turned off, and 2 seconds exposure delay.  Files ...
  • Yes, it just seems rather prominent in the example I showed -- more than a pixel or two wide (roughly three or four, I'd say) on a 24 MP DX sensor, anyway.  Still, I agree, it's a non-issue with ...
  • Yes, of course corners are not as sharp as center, and yes, stopping down to f/5.6 or f/8 helps from what I've seen so far. http://www.nikonusa.com/en/Nikon-Products/Product/Camera-Lenses/AF-S-DX-N ...
  • I'm now convinced the 16-80 at 80 mm f/5.6 focused at infinity on my D7200 is substantially sharper than my 24-120 f/4 at 120 mm was at any aperture on my D750 (before I sold the 24-120 -- sorry, ...
  • Created discussions 16-80 f/2.8-4 lateral CAs
    Getting to know my 16-80 f/2.8-4 better today I shot this building at 80 mm f/5.6 (NEF, converted to JPEG in Lightroom at default settings, downsized to 1 MP): Here are full-resolution crops of the ...

  • I posted a few of my first shots with it here: http://www.dpreview.com/forums/post/56186237
  • Thank you for the kind words!
  • The 17-55 was meant for professional (ab)use at a time when all professionals using Nikon DSLRs were using DX because there was no FX yet.  It's a very rugged lens with lots of metal in it (and ...
  • I was hoping the 16-80 would have less distortion than the 24-120 on FX, which Markus Stamm at Photozone.de reports as -3.55% barrel at 24 mm and 2.05% pincushion at 120 mm, but the 16-80 looks ...
