Very recently, we had the chance to play with the Sigma 24mm f1.4 lens that was recently announced. As the latest addition to the Art series of lenses, this is Sigma’s third full frame prime lens that is part of their Global Vision initiative. The lens has a minimum focusing distance of 9.8 inches. Additionally, the 24mm incorporates both “F” Low Dispersion (FLD) glass and Special Low Dispersion (SLD) glass, has an optical formula 15 elements in 11 groups which the company claims to help to minimize chromatic aberration of magnification especially in the edge of the image field, and has aspherical elements placed near the rear of the lens. Finally, the lens has manual focus override even when the autofocus is activated.
We played with a pre-production copy, and what we saw got us more excited than any other lens that we’ve seen so far.
