  • I own a D300s. It is in perfect condition although it is not in use any more. I tested it yesterday together with a FX AF-P 70-300 f/4.5-5.6 E lens and it worked perfectly. This lens does not have ...
  • FYI I just tested the FX AF-P 70-300 f/4.5-5.6 E on a D300s camera, and it worked perfectly (the lens you are showing on the upper picture). The D300s was introduced in July 2009 while the D700 ...
  • Replied in Made where?
    Of my 18 AF-lenses for Nikon DSLR, 8 are made in Japan, 6 in Thailand and 4 in China. The only lens in need of repair was one made in Thailand (warranty). Of my 6 Nikon DSLRs and another 2 DSLRs ...
  • Iguazu falls in to the area of landscape photography in my view. The D850 will of course have more resolution to offer, dependent on the lens you are using. Again, the 16-35 should be quite ...
  • Replied in Sport lens
    Your picture from a horse show is taken at 81.3 mm focal length which is very close to 300 mm on a D5600 (if my calculation is correct). I would assume that a closer view would be of interest ...
  • As already explained the perspective is only determined by your position and not anything else. The distortion is caused by the lens. Of course if you hold the camera at an angle that will also ...
  • According to OpticaLimits.com (photozone.de) the DX 12-24 has distortion at 12 mm of -1.7 % (barrel) and 0.3% at 16 mm. While the FX 16-35 has at 16 mm -4.3 % distortion and at 21 mm -0.9 %. This ...
  • Replied in F6.3 lenses
    The D810 and D7500 both have 51 focus points, basically capable of operating down to f/5.6. On the D810 11 focus points also work down to f/8 while on the D7500 only the center focus point is ...
  • And why is that? Because such an adapter being able to adapt any Z-lens to an F body is not possible.

  • Replied in Pure nonsense!
    Who or what is “Ken L.Wheeler” a.k.a. “Theoria Apophasi s” a.k.a. “the Angry Photographer” ? And why does he make these ridiculous youtube videos? They are provocative and filled up by pure ...
  • Replied in 1600
    "we managed more than 1600 images and several 4K video clips on the Z 7 with a single EN-EL15b" . . from https://www.dpreview.com/articles/4160692612/nikon-z7-what-you-need-to-know-about-nikon-s-fi ...
  • "You have to shoot at f/8 wide open" No, why? You have the free choise to do whatever makes the image you are looking for, IMHO. Hand holding do not require sport mode. Actually the 200-500 has a ...
  • Added 1 photo to their gallery
    DSD_0802c
  • I have just tested a D300s, D500, D810 and D850 to see what LV is doing. I believe the D300 and D300s operate in the same way (?) The D300s closes down to the selected aperture when in LV. Pushing ...
  • The newest is the Nikon 16-80 f/2.8-4.0 E VR which should be very good. An older but still very good alternative is the Nikon 16-85 f/3.5-5.6 G VR. Both lenses have advanced VR functionality with ...
  • Replied in Enjoy the D4!
    The expected new mirrorless from Nikon will probably be good. They have had the Nikon 1 as a test vehicle for 7 years and I suspect they have learned a few things. The known weaknesses with ...
  • Replied in diffraction?
    If you read the material you are pointing at you can see: “Diffraction thus sets a fundamental resolution limit that is independent of the number of megapixels, or the size of the film format. It ...
  • Replied in diffraction?
    No, diffraction is not impacted by the camera model. It is something happening in the lens if the the aperture is too small.
  • Yes. The 50 mm on FX have a diagonal FoV = 46.8 degrees. On a Nikon DX camera (Crop factor = 1.53) it will have a diagonal FoV = 31.7 degrees. In comparison a 75 mm on FX will have 32.2 degr. Just ...
