Sigma 65mm f 2 dg contemporary vs sigma 70mm f 2 8 dg macro art?

Both are Sigma primes for full frame, with autofocus and no stabilisation, but they're built for different jobs.

The Sigma 65mm f/2 DG Contemporary is the faster lens. Its f/2 aperture gives more light and more background blur, which suits portraits, low light and people. It mounts on Sony E and L-Mount only.

The Sigma 70mm f/2.8 DG Macro Art is the one to pick for close-up work. It's a sharp life-size macro, and it also mounts on Canon EF, so it's the better choice if you shoot Canon.

If you want a general-purpose portrait lens, go with the 65mm. If you want to photograph small things up close, the macro is the one. For more on aperture, see the lens guide.
