Update: The Sigma 24-70mm f/2.8 DG DN Art lens for Sony E-mount and L-mount has officially been announced. This newly-designed Art zoom lens is designed to be a large-aperture standard zoom for full-frame mirrorless camera systems. The Sigma 24-70mm f/2.8 DG DN Art lens has three aspheric lenses to subdue chromatic abberation and Super Multi-Layer Coating and Nano Porous Coating to help achieve high-contrast and clear image quality.
With a dust and splash-proof body and a zoom lock mechanism to prevent the lens barrel from extending unexpectedly, the Sigma 24-70mm f/2.8 DG DN Art lens is a perfect addition to any professional events photographer's kitbag.
If you're a Sony mirrorless camera user and you're looking for a versatile piece of glass that can carry you through almost any professional shooting situation, then the rumored Sigma 24-70mm f/2.8 FE lens might be exactly what you've been waiting for. With the first image having recently been leaked, it appears as if this handy lens will be making an appearance at some point in 2020.
There is currently a Sony-made 24-70mm f/2.8 GM, which retails for £2,269.00 and weighs 886g. While we don't have any concrete information on the Sigma 24-70mm f/2.8 FE lens, the leaked photo shows a surprisingly compact lens - especially if you imagine away the lens hood.

While we can't really speculate on how this seemingly smaller size will impact the weight of the lens, we do hope that this might point towards Sigma's offering being lighter than Sony's own 24-70mm f/2.8 lens.
You might wonder why exactly size and weight are so important - after all, surely the quality of the glass is paramount. Well, yes it is, but when you're a working pro photographer and you're having to lug around all of your equipment over long stretches of time, you can truly start to appreciate the magic of a light and compact lens.
Plus, one of the main draws of investing in a mirrorless camera is that it's ostensibly meant to be lighter than a DSLR equivalent. While this is often true for the camera bodies themselves, some pieces of glass don't quite live up to these expectations.
If Sigma have created a truly light and compact 24-70mm f/2.8 FE lens, we can see this proving truly popular among both amateur and professional Sony mirrorless camera users.
As reported by rumor website Sony Alpha Rumors, the Sigma 24-70mm f/2.8 FE lens will likely be announced on 06 November. However, this will only be an announcement of the lens' development, so we won't actually see the lens on the market until 2020.
