Full frame mirrorless Canon RF mount devices were launched in September 2018. Along the launch of two cameras the producers showed also as many as four lenses. Certainly launching such models as the RF 24-105 mm f/4L IS USM, the fast 1.2/50 standard lens, or the budget 35 mm wasn't any kind of surprise. Still such an instrument as the Canon RF 28-70 mm f/2L USM, showed along the ones mentioned above, was a huge and a very positive surprise - let's face it, it's a pretty unique lens.
Other producers couldn't find an answer to that for a very long time. Sigma approached these parameters in the most intensive way – in February 2021 they presented the budget C 28-70 mm f/2.8 DG DN and lately they also tried their hand at even more untypical parameters, launching the A 28-45 mm f/1.8 DG DN and the A 28-105 mm f/2.8 DG DN models.
Sony wasn't very imaginative in this section - in November 2024 they decided to present the 28-70 mm with a fixed f/2.0 aperture. It was supposed to differ from the Canon when it comes to smaller physical dimensions and a noticeable lower weight. How the slimming down affected its performance? We hope that our test will be able to answer this question and many more – enjoy!
