  • I consider myself an advanced amateur with absolutely no ambition to become a pro.  As such, I use a 24-120mm f/4 for my "all-around travel lens" and I'm quite satisfied with it in that role. On ...
  • I haven't "shot it against" my 70-300mm VR, but I do own and use both. In a travel kit, I prefer the latter lens even though it weighs half a pound more than the 75-150mm. In part this is because ...
  • Points for trying to fight the good fight; I gave up on it. Rightly or wrongly, people do equate the amount of defocusing with the term 'bokeh.' Don't believe me? Last year the USPTO accepted and ...
  • Replied in Lines per mm
    Without knowing the target contrast percentage (MTF) at that frequency, 50 lines per mm is not all that useful a statistic. It also seems to be a very low target. Even 50 line pairs /mm would be a ...
  • My apologies.  In case it was a bit confusing, by D3xxx I was using a shorthand for the 4-digit model numbers.  (D3000, D3100, D3200, and D3300).  Ditto for D5xxx; the D5 and D500, when released, ...
  • Among the criticisms I've heard or read: (1) Nikon chose a design which optimized for autofocus speed and accuracy, but which resulted in a substantial reduction in maximum focal length at short focus. ...
  • I own 5 Sigma lenses. 3 of them have had to be rechipped, including a screwdriver 28mm f/1.8.  Were I to buy a Nikon Df, those 3 plus my 150-500mm would need a new rechipping. The exception is my ...
  • Welcome to the quagmire known as "Nikon lens compatibility." The FM3A is a manual focus film camera.  Not surprisingly, it can't autofocus with any lens, AF-S or not. Certain older autofocus film ...
  • As I've said all too often, though, do not try to understand Nikon's marketing or product line strategy. That way lies madness. This recently revived thread asks the same question: http://www.dprev ...
  • AF-I lenses were discontinued in 1998. The last non AF-S autofocus lens Nikon introduced was the 10.5/2.8 G ED Fisheye in 2003. Some other older "screwdriver" autofocus lenses remain in production ...
  • Replied in nikon 24mm pce
    I'd start by contacting the Nikon Service Facility in your country: http://imaging.nikon.com/support/facilities.htm Nikon USA offers a very limited number of parts to "civilians," but I believe the ...
  • As a rule of thumb, if using a polarizer would impact AF performance, the lighting is such that you probably don't need said polarizer.  A typical outdoor scene exposed for shadows has an ISO 100 ...
  • All of them are FX or film lenses; I don't know of any 35mm f/1.4 DX lenses in Nikon mount. Focal length is focal length; any of them will give you approximately the same field of view as a 35mm ...
  • First, a quick comparison. 35mm f/1.4 Samyang Weight: 654g 35mm f/1.4 Sigma Weight: 665g 35mm f/1.4 AI-s Nikon Weight: 400g 35mm f/1.4G Nikon Weight: 600g 35mm f/1.4 Zeiss ZF.2 Weight: 830g I can't ...
  • For a private sale, $275.00 is top dollar.  KEH has them in EX condition for $289.00. I'm also going to offer a counter-intuitive opinion -- I wouldn't buy this for use on a DX camera, but I might ...
  • For a setup with backlighting, I'd suggest staying with lenses with multicoated optics.  I'm also hesitant to recommend the 55mm f/2.8 AI-s due to issues with sticky aperture blades. The problem ...
  • In addition to the mask, you'll need a way to keep the negative or transparency flat. Almost any medium or short macro lens will work for this.  1:2 is sufficient even for 645 film.  If you plan to ...
  • Before the acceptance of f/2.8 zooms, 85mm f/1.4 and f/1.8 lenses were used extensively to shoot basketball. But it really depends on where you are shooting from and how much freedom of motion you ...
  • Replied in Own Both....
    My macro "herd:"
  • While it doesn't appear that Hoya makes a modern CPL in 95mm yet, I quickly found the following options: (1) Nikon (newly announced) (2) B+W (F-Pro Kaesemann MRC)
