Digital Camera World Verdict

It might seem an odd focal length for a prime lens but the 42.5mm equates to 85mm in full-frame terms. Add the super-fast f/1.2 aperture and it makes the Panasonic Leica DG Nocticron a perfect candidate for portraiture on Micro Four Thirds system cameras. Build quality and handling are superb, while image quality is simply stunning. This lens certainly isn’t cheap to buy but it’s worth every cent and more.

Given that depth of field is governed more by ‘actual’ than ‘effective’ focal length, getting a tight DOF is a challenge for the Micro Four Thirds system, due to the cameras’ 2x crop factor. The Panasonic Leica DG Nocticron 42.5mm f1.2 ASPH Power OIS comes to the rescue. Its effective focal length of 85mm gives an ideal working distance for portraiture, while its extra-wide f/1.2 aperture delivers a tight depth of field for isolating the main subject by throwing the background out of focus.
