Macro Lens Question

Discussion in 'Lens Lust' started by Jim Strathearn, Sep 11, 2005.

  1. I wasn't sure where to ask this, so I'll ask it here.

    There is a 1.5x crop factor associated with the DX sensors. I understand (at least I THINK I understand...) how that works with regards to lenses and "end result" focal lengths. However, does this crop factor also affect macro reproduction ratios? In other words, would a 35mm 1:1 macro lens be a .67:1 macro lens on a DX sensor? (Or something to that effect...)

    I guess I'm wondering if that crop factor can make a 1.5:1 lens a 1:1 macro...

    No. The magnification ratio referrs to the size of the object as compared to the size of the image. At 1:1, the image is the same size as the object. The crop factor means that there is LESS of the image captured in the frame vs the same lens on a 35mm film camera, but the size is the same.

    For example, suppose you photographed a 1/2 inch bug with the 60mm micro. It would reproduce on film and on a digital sensor as 1/2 inch long.
