Time to play "Guess the lens" again, please

Discussion in 'Lens Lust' started by Pa, Apr 6, 2007.

  1. Just fiddling around today, and decided to compare my two least expensive lenses: Nikkor 50/1.8 and Tamron SP 90mm macro MF. Tripod mounted, MLU, f/5 for both. The 50mm image is cropped to approximately the same magnification as the 90mm image, which is uncropped.

    Which is which?





    Thanks for playing.

    I'd have to hope that the Tamron was #2. Much sharper, at least on my monitor.

  5. Nikon #2
  6. Tamron 1. 50/1.8 is image 2

    #2 is sharper and that makes it the Tamron to me.
  8. The second has a greater depth of field, so I guess that is the cropped image and therefore the 50.

    I'd guess #2 is the 50mm.

    I'd say Tamron is #2
  15. #2 is Nikkor.
  16. O.K. I'll reveal the truth, as I know you all are waiting with bated breath.

    Nine out of thirteen respondents got it right; #2 was taken with the Nikkor 50/1.8. Either you folks know your lenses, or you used the obvious clue that #1 is the only one with the aspect ratio of an uncropped image.

    Frankly, I was surprised by this result. I really expected the dedicated macro lens to produce a sharper image. Of course it will focus much closer and will give 1:2 magnification. However, I can get that with the 50 by cropping, and apparently with increased resolution!

    WOW! Yes, I'm shocked. I was definitely one of those who thought a dedicated macro lens would produce a sharper image!
    Glad I kept my little 50mm 1.8 lens....never even thought of using it for macro!
    Thanks for telling us, I kept clicking back into this thread to find out the results :biggrin:

  18. Yes, the "nifty fifty" wins again!

    I must point out, however, that the Tamron SP 90 that I have is an older manual focus lens, and may not be representative of what the current version is capable of.
  19. #2 is Nikkor

    OOPS! a little late
  20. Hey, you're right!
