Tamron SP AF 60mm f/2 Di II LD (IF) Macro 1:1

Macro lens

A macro lens by Tamron for APS-C cameras, 60mm f/2. A fast life-size macro lens for APS-C DSLRs.

What it frames like

Its full-frame-equivalent focal length on the sensor it was made for.

How wide 60mm sees on each sensor it covers.

f/2 wide open, to scale against f/1.4.

On APS-C (Nikon F): like 90mm on full frame; f/2 gives about the depth of field of f/3 there.
On APS-C (Canon) (Canon EF): like 96mm on full frame; f/2 gives about the depth of field of f/3.2 there.
Not usable on the larger-sensor bodies of Canon EF: they have no crop mode (and Canon's EF-S lenses don't even mount on them), so it is for APS-C bodies only.
On the larger-sensor bodies of Nikon F: it works with the camera in a APS-C crop mode, at fewer megapixels.
