Description

Here’s a close up shot of a flower taken with the S1. The focal length was 70mm with the settings being f2.8 and 100 ISO. As you can see, great bokeh. Pros And Cons: Pros: Another benefit to the weight of this lens is that you can shoot for long periods of time without your wrist or arm aching, which is ideal if you predominantly want it for video. The new SIGMA 28-70mm F2.8 DG DN | Contemporary redefines the standard zoom for L-Mount and E-mount mirrorless cameras by combining outstanding optical performance, an F2.8 constant aperture and a lightweight and compact body. It has a similar optical design to the 24-70mm F2.8 DG DN | Art, but is significantly smaller and lighter at only 56% of its weight. In fact, at the point of release it is the smallest and lightest standard zoom with a constant F2.8 aperture for full-frame mirrorless cameras.

Field review: Sigma 28-70mm F2.8 DG DN

The 28-70mm f2.8 DG DN Contemporary lens is superb because it is so versatile. This is a lens that has the optics to deliver you professional quality results yet at the same time, it’s small and light enough that you can use it for more casual activities like taking it on vacation or outings with friends. It also has the focal length range that is great for all types of photography, and a large enough maximum aperture that can help you be more creative, and give you more flexibility in different conditions. Honestly, this is the type of lens that we need more of in the L mount system, and I’m very happy to see Sigma coming out with them. If you’re trying to build a compact system, and are currently looking for lenses that not only are optically exceptional but also compact and versatile, this zoom should definitely be on your list of lenses to consider. 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. Budget alternative: The Sigma 35mm f/1.4 DG HSM Art Lens may not be quite as bright, nor as sharp, and it’s not built specifically for mirrorless cameras, but it’s still available in L mount and is a steal for less than a grand.

The optical design of the SIGMA 28-70mm F2.8 DG DN | Contemporary is largely based on the 24-70mm F2.8 DG DN | Art, which is renowned for its outstanding optical performance throughout its zoom range.

Sunstars are relatively pleasing, with 18 rays thanks to the nine aperture blades. They're not as tight as they could be – each ray splits and diverges into two rays – and as expected stars on the wide end look better than those on the telephoto end where they can appear a bit 'messy'. The images all came out sharp and clean in both cases, but the time to autofocus with the Sigma lens always took noticeably longer. On a Leica SL-2, this delay made using the Sigma version almost unusable when I attempted to shoot a moving subject wide open. Sigma 24-70mm DG DN Art at 24mm and f/8 Leica Vario 24-70mm f/2.8 at 24mm and f/8 I have a question. Is it very difficult for lens manufacturers to achieve the focal lengths from 24-28 in such a lens?We always used to think that this Sigma Art lens was massively big and heavy for a 50mm f/1.4 prime, but that’s before Panasonic’s competitor came along. As it stands, the Sigma is noticeably smaller and lighter than the Panasonic, and isn’t much more than a quarter of the price in the UK, although it’s not such outstanding value in the USA, where it’s closer to half the price of the Panasonic. Like the Sigma 35mm f/1.4 Art lens, the 50mm was originally designed for DSLRs and has been adapted for L-mount cameras. The optical path and ring-type autofocus system are largely unchanged and, also like the Sigma 35mm Art lens, there are no weather-seals. Even so, build quality is very good and the lens certainly delivers in terms of image quality, making it a great buy in the UK. But we all know that in practice a really equivalent lens for mft is often times not practical or possible. There is just no equivalent to a f/0.9 lens for the system with half the image cycle. (It would need to be f/0.45)

The Sigma 28-70mm f/2.8 DG DN Contemporary lens features 16 optical elements in 12 groups. There are three aspherical elements, two FLD elements and two SLD elements. The lens features a 9 blade aperture and has a minimum focus distance of 7.5” (19cm) at 24mm. As you zoom out this changes to 15” (38cm) by the time you get to the 70mm focal setting which affords a great deal of versatility shooting subjects at close range. A lens with a maximum aperture of F2.8 is fairly good in low light, though obviously not as good as lenses with even larger maximum apertures. In many cases, cameras will focus with the lens aperture wide open and then close it down to the preset aperture choice at the moment of capture. A lens with a smaller maximum aperture is going to be at a disadvantage in low light conditions because the physical aperture is smaller than alternative lenses, meaning that less light can reach the sensor. F2.8 is what I would call a “medium” maximum aperture, but it is wide enough that one should be able to shoot weddings or events with the lens and get solid results. In the center, bokeh balls are almost perfectly round but as you creep out towards the edge of the images, it starts to distort slightly into more of an oval shape when shooting at f/2.8. It's noticeable but not distracting, so unless you're a bokeh connoisseur it's unlikely to bother you.I should point out that the technology Sigma uses in its lenses is not the same as the linear, electromagnetic system that Sony uses in their newer lenses. If you’re shooting sports or any other fast-moving subject, I don’t think Sigma’s design will outperform modern Sony lenses. This lens is not designed for that type of application, but I do think that is something most people will know going into it. No, EF-M lenses won't fit full frame Canon bodies. *EF-M is kinda all by itself in terms of its lenses only fitting its cameras.* Not sure why you'd want to adapt the dozen or so lenses available for this system anyway, when there are so many EF and EF-S alternatives. However, you can first party Canon adapter mount any and all full frame EF, and EF-S, lenses to any EF-M camera. There are also third party adaption options which include speed boosters to make the FoV and capture on the M camera full frame equivalent. To top it off, the 28-70mm f2.8 DG DN Contemporary lens does focus very closely as well. The minimum focus distance at the 28mm focal length is 7.5″ (1:3:3 magnification), while at 70mm, it is 15″ (1:4:6 magnification). This adds even more versatility to this zoom.
