    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?

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

    #2 is sharper and that makes it the Tamron to me.

    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.

    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:

    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.
