Sigma lenses

Once again, it is floating around that a 85mm f/1.4 Art is to be announced in 2015, and released in 2016. An ultra wide-angle zoom lens is also mentioned.

Since that 85mm f/1.4 Art is arguably the most requested Sigma lens, differentiating wishful thinking from real bits of info is the tough part — but we indeed expect another announcement this year.

Common sense would tend to something that doesn’t exist in the Sigma lineup, like a 135mm f/2. Sigma is quite proud of the recent 85mm f/1.4 EX and without a doubt updating it so quickly was not in the plans, but the demand has been too high to ignore it.

Sigma 24mm f/1.4 DG HSM Art on Canon EOS 5Ds R (simulated)

As of mid-2015, there’s no better lens testing platform than the EOS 5DS R. Just published, both on the 50MP Canon camera:

  • Sigma 24-35mm f/2 DG HSM Art sample photos at DPReview here. 45 full-size shots, most wide open.
  • Sigma 24mm f/1.4 DG HSM Art review at Photozone here. Excellent sharpness in central areas, but the lens struggles elsewhere at wide apertures, which is not terribly surprising. At least the performance is assessed in the proper context.

While the Sigma 24mm f/1.4 DG HSM | A is certainly not a bad lens, it is still the weakest prime of the Art series that we have tested so far. To be fair – an ultra-large aperture 24mm lens is simply more difficult to design than a 35mm or 50mm lens. This also applies to the Canon EF 24mm f/1.4 USM L II. While we have tested the Canon on 20mp only so far, it already struggled with the image corners at large apertures here so it’s very unlikely to be better on the EOS 5Ds R. Thus if you struggle to decide between the two, we’d actually recommend to have a closer look at the Sigma.

14mm f/4 lens

The Sigma dp0 Quattro is in stock at B&H Photo.

Focus Numerique has tested the Sigma dp0 Quattro (English translation) and came away stunned by the resolving power of the 14mm lens.

  • Peak sharpness is reached wide open (f/4) for most of the frame, with only the extreme corners scoring very slightly below the f/5.6 aperture. Not enough for the eye to perceive it.
  • At f/4, center resolution is only two hundredths short of the theoretical maximum for the Quattro sensor.
  • Resolution figures in the corners are lower than in central areas, but perceived sharpness remains very high wherever one looks.
  • For the best results, don’t stop down past f/8.

Sigma 24-105mm f/4 | A

B&H Photo has received copies of the elusive Sigma 24-105mm f/4 DG OS HSM Art (Nikon mount).

The lens was rumored to be discontinued, but the official reason for the widespread backorders in the past few months is a temporary production halt that is normal for lenses that don’t sell much.

Thanks John and Norbert.
