Sigma has officially launched its first Canon RF mount lens: the 18-50mm F2.8 DC DN Contemporary. We knew the lens was on the way after Canon finally gave the key to the door to its RF mount to Sigma and Tamron in April, and now we know the 18-50mm will hit shelves on July 11.
It's time. Canon's superb crop sensor (APS-C) mirrorless cameras like the Canon EOS R7, EOS R50 and EOS R10 (which we ranked as the best camera for beginners) are at a standstill; Up to this point, these cameras have been severely lacking in decent lenses, especially compared to top Sony cameras like the A6700, which enjoy a much healthier option.
The tide is starting to turn and the Sigma 18-50mm is an excellent third-party addition to RF support. The APS-C lens offers a 24-75mm equivalent focal length with a constant f/2.8 maximum aperture – the middle lens in the classic trinity of f/2.8 zooms.
The classic versatile zoom lens is not only a great everyday lens for landscapes, portraits and events, it is also immediately the fastest RF-S lens available thanks to its f/2.8 aperture; Canon's current four RF-S lenses are smaller and more variable. aperture zooms.
It's also a great value lens, with an introductory price of $499 / £479 / AU$699.
As it stands, we expect the Sigma 18-50mm to have the best optical quality of any Canon RF-mount lens for APS-C, although you can technically use Canon's full-frame RF lenses with APS-C cameras, and there are many. More full frame Canon RF lenses available.
Sigma's proven APS-C lens is now available in L-mount, Sony E-mount and Fujifilm X-mount versions, and has been tuned for Canon RF mount to support Canon AF Servo and lens aberration correction. camera. and to ensure that the autofocus unit and communication are up to date with Canon cameras.
It's splash and dust resistant and weighs just 10.6 oz / 300 g, which is quite a feat for an f/2.8 zoom lens and makes the 18-50mm size a perfect match for cameras without Canon APS-C mirror.
There are better lenses available for macro photographers: the maximum magnification ratio is only 1:2.8 at the wide-angle focal length and 1:5 at the telephoto setting. However, that doesn't stop the Sigma 18-50mm from being the most versatile lens available for Canon APS-C mirrorless cameras.
There are five more lenses from Sigma in the pipeline, including a quartet of fast-aperture f/1.4 primes set to launch later in 2024; the 16mm F1.4 DC DN (estimated at $449 / £389), the 23mm F1.4 DC DN (around $549 / £479), the 30mm F1.4 DC DN (estimated at $339 / £319) and the 56mm F1.4 DC DN (around $479 / £419).
Canon's camera hardware is undeniably good, and now native lenses are arriving to back it up. Thanks to Sigma, it's a new dawn for Canon's APS-C mirrorless cameras.
