The only real issue that I even really encountered is there were times when I wish I had just a bit more width in terms of focal length. There were moments when I wish I had the extra 4mm from the Sigma 24-70mm f2.8 DG DN Art lens I was reviewing at the time as well. 4mm does not sound like a lot but when we’re talking about the wider end of the spectrum, it can make a larger difference. I feel like the 24-70mm gives me just that extra bit of versatility and flexibility. With that said, I’ve never been a fan of the 28mm focal length, so I’m sure that comes into play here as well. The lens features just one lightweight focusing element, which keeps the AF unit small. This, along with a quiet and fast stepping motor, makes for responsive and near-silent autofocus performance. Potentially a highly attractive 'step-up' lens for mirrorless shooters, Sigma promises that image quality from this compact zoom will be comparable to the Art-series 24-70mm F2.8. We've had the new lens for a few days, and we've been shooting with it on the Panasonic S1R so you can get a first look at its image quality.

If you thought that ‘compact system cameras’ were relatively small and lightweight, Panasonic’s S series bodies will make you think again, and this lens is frankly enormous for a 50mm prime, weighing in at almost a kilogram. Even so, handling is refined with tactile aperture and focus rings, the latter having Panasonic’s usual push-pull mechanism for swapping between autofocus and manual focus. Autofocus itself is super-fast and virtually silent, powered by dual linear and stepping motors. The optical path includes two aspherical elements and three extra-low dispersion elements, along with a particularly well-rounded 11-blade diaphragm. Image quality is simply spectacular in all respects. Even so, this hefty lens comes with a similarly weighty price tag.Importantly, the lens is also fully compatible with the "Direct Manual Focus (DMF)" system feature of Sony cameras that enables the user to instantly switch between autofocus and manual focus.

But keep in mind that 24-70/2.8 art is not that sharp. I am a big fan of sigma after using 50/1.4 and 85/14 art, but found the 24-70 art lens soft. But in all fairness, zoom lenses at this range are never close to prime performance wide open.A 50-250 f/2.8 will easily be 2x the weight/bulk, 2-4x the price, and sell 10-20x less units compared to a 70-200.
