The next Art line Sigma is another undeniable hit. Instead of wax eloquent in the summary we just would like to say that the Sigma 50-100 mm is one of the sharpest lenses we’ve ever tested. Mind you it is a zoom lens, more difficult to correct than a classic “prime” when it comes to optical aberrations. You can also comment on the price. So far most of the very well-done Art line lenses were priced at about 3000 – 3500 PLN. In the case of the 50-100 mm f/1.8 model you enter a level of 5000 PLN. On the one hand it is a risk for Sigma; on the other hand I don’t have the slightest doubts that the same lens but called Canon or Nikkor would cost noticeably more.
