Test for sharpness with D2X

Discussion in 'Nikon DX DSLR' started by Gilles, Jul 28, 2005.

  1. Picture taken with PC-85 with view camera tripod, exposure taken with handheld meter, mirror up.

    So, given the technical solution, and high subject contrast, are we supposed to find a lot of detail in the test picture :?:

    It certainly looks like this and is indeed expected, because the 85PC is a remarkably sharp lens in my experience. Putting it on the D2X won't make it a lesser performer either :D
     
  3. How do you reduce the size of the picture without loosing all the sharpness?

    The original is very sharp indeed (you can read everything on the plaque) but not the reduced size that I have up there.

    This is impossible as such. You can however make a small image showing the outline of a 100% crop, and the overlay the crop on the picture.
     
  5. Here a 100% crop of the original, picture taken at between 100 and 150 feets from the subject.

    I'd say the sharpness suffices ):

    The 85 PC is among the lenses that show D2X to its best advantage. Other examples are 200/2 VR, 85/1.4, 50/1.4 & 1.8, 105/4, 50-135/3.5, 50-300/4.5, 35/1.4, 17-35/2.8, 28-70/2.8 just to name some coming to mind. Landscapes with 200/2VR can be breathtaking in terms of the sheer detail. I might even be convinced sufficiently to go into landscape photography, otherwise a field I try to avoid.
     
  7. Oh, oh.... I feel a new bout of LLD setting in! :)

    Bjørn, thank you, btw, for your site and providing such a great resource on lenses. I've referenced it many times!

    Nice to see the 28-70 f/2.8 in your list. I just bought one :D
     
  9. I find that the biggest problem of the D2X is the contrast, I wish they had put a -2 and -3 contrast.
