Sigma 24-70mm F2.8 DG DN Art Sony E Mount 578965

Product Information

Proč tento model? Sigma 105mm měla cenovku 40 tisíc. Udělala by nejlíbivější proporce obličeje, ale ten bookeh už je příliš moc. No a 85mm Sigma zase není tak daleko od 70mm, cenovka 36 tisíc. Navíc zoom do 70mm za 20 tisíc. Tak jsem si vybral budgetovku (zoom), která bude univerzální a povedlo se. Z koupě jsem pořád nadšený i po 2 měsících. Objektiv je sice větší, ale přitom žádná hrůza. Jediné drobné mínus je sluneční clona, která jde docela špatně odšroubovat (je zapotřebí hrubé síly).

So let’s start with my distant landscape scene, angled as always so that fine details run right into the corners. Here’s the lens at 24mm f2.8 and taking a close look in the middle reveals a tremendous amount of detail and high contrast even with the aperture wide-open. Closing it one stop to f4 provides a tiny boost for pixel-peepers, but as far as I’m concerned, it’s looking great in the middle at f2.8. For E-mount shooters, the nearest alternative might be the Sony FE 24–70mm F2.8 G Master II lens, which is more than double the price of the Sigma. However this newer lens brings much to the table, improving upon its predecessor in almost every way. The older 24–70mm F2.8 GM is still available, often at a discount, but it's never been a favorite of ours.

On to using the lens itself, the first thing I noticed from the Tamron compared to the others was how light this lens is. At only 540g it is nearly half the weight of the Samyang and just over 300g lighter than the Sony. This made it very easy to carry and use.The 24-70mm lens is a good place to start looking if you are wanting a full-frame lens that will be able to cover a diverse variety of photography types. From the widest part of the lens at 24mm for Landscapes to the narrowest part of 70mm for Portraits. And the in-between for almost all types of photography. Starting from the end of the barrel is an 82mm filter thread, followed by a free-spinning and very smooth manual focusing ring. Behind this is an AF / MF switch and two programmable function buttons, followed by the zoom ring which extends the barrel by about 35mm when zoomed to the longest focal length. Casual hobbyists buy them, even though they’re usually massive, hefty beasts to be lugged around all day on your family outings or random walkabouts or tourism. Image stabilization: None of the lenses in this comparison offers optical stabilization. But the full-frame mirrorless cameras from Sony, Nikon, and Panasonic provide built-in sensor-shift stabilization. [0]

The main disadvantage I found with the AF 24-70mm was the weight. Compared to the other three lenses, coming in at 1027g, it was by far the heaviest out of the four. This did mean after longer periods of use I started to feel the weight in my arms, especially when moving the camera and lens up to my eye for a shot through the A7’s EVF. This may not be an issue for other users, especially if using a tripod for landscapes or for video, but I would suggest thinking it over if wanting to use it for the likes of handheld or street photography. So, you shoot Sony and are currently using a more basic zoom kit lens and want to upgrade to a more versatile all-rounder zoom lens? Or you've just got into the Sony Alpha Mirrorless system and are looking for that first lens to go with your Sony Alpha camera?

Taking a close look in the middle of the frame tells the same story as at 24mm, so lots of fine details and high contrast out of the gate, with a very mild boost if you can stop it down to f4.

Optics: The Sigma has the most complex design in this comparison with 19 elements (including 8 special dispersion elements and 3 aspherical element) in 15 groups. That makes 30 glass/air surfaces where reflections can cause problems. Sigma employs nano coating to reduce reflections. Of the lenses in this comparison only the Nikon has a special coating on the front lens to repel water, dust, and dirt, and make for easier cleaning. [+] Whereas the lenses we will be reviewing below can give the same results (if not better) than some dedicated prime lenses. Meaning yes, you can use a zoom lens for portraits or street photography with these options below. Having said that, I did find I enjoyed one lens the most and found the results most to my liking; the Sigma. Because of the lovely build quality, the extra aperture blades giving fantastic bokeh and depth of field in the photos, and all the same functionality as the other 3 at a reasonable price, I will say the Sigma to me is the best 24-70mm for Sony currently on the market. The score of 0[-]/5[0]/11[+] shows that the Sigma 24-70mm f2.8 DG DN Art is quite well-featured with the unique option to get the lens-mount swapped. The Sigma 24-70 produces severe flare at the longer end of the focal length range if the sun (or a bright light) is close to the image circle.Having a slightly different focal length to the other lenses, the Tamron does have a narrower field of view, starting at 28mm and finishing at 75mm (32 - 75°). But I did not see a huge difference in this when using the lens, you can still get very much the same shots as you would with the other 24-70s. The lens itself was very sharp and gave edge-to-edge sharpness throughout the range of the zoom. We did note some field curvature for macro shooting, which leads to rather soft corners, but the 24–70mm F2.8 isn't an incredibly sharp lens when shooting close-up in the first place. Stopping down yields very good corner sharpness. Yes, the Sony GM II is a bit better, but it's not like 2-times or 200% better than the Sigma ART, but costs a lot more. Into the end, its the 6 inch behind the camera, not lens. Rozdíl Sigma versus Sony jsem viděl okamžitě. Prvních pár fotek s tímhle perfektním zoomem a jásal jsem "konečně!". Četl jsem několik recenzí a shlédl x porovnávacích videí. Prý Sony a Sigma mají mezi sebou nepatrný rozdíl. Pff, možná tak leda pro téměř slepé!!! Zcela vážně. Musíte být slepí, abyste neviděli ten obrovský rozdíl. What really matters is Sigma's new 24-70mm Art E-mount lens really delivers the goods and is terrific value at the price.

Unfortunately, despite the dramatic number of points the appearance of the sunstars is quite diffuse. If you are a landscape photographer looking for sharp, clean and dramatic sunstars you may want to look elsewhere. Longitudinal / lateral chromatic aberration (fringing) Although they are both rated 24-70mm lenses, the Canon 24-70 L is noticeably wider at 24mm than the Sigma when the subjects are not distant. Sigma France kindly gave me a month to the put their new lens to the test. I’ll touch on technical aspects such as corner sharpness and distortion, but this was an opportunity to try a lens in the field and get a sense of whether this is a piece of gear that I genuinely want to add to my bag. If you want to pixel-peep, seek out the MTF charts and endless photos of walls at different apertures elsewhere. If you want to know what it felt like to use this lens for a month, whether it inspired me to go out and shoot photographs, and whether it is the workhorse that it claims to be, read on.Measuring 3.5" x 4.5" (88.7 x 115.5mm) and weighing 25.2 oz (715g), the Sigma is still smaller and lighter than pushing/pulling on the nicely-sized and smooth turning focus ring is required to engage/disengage the manual focus gearing. As a newer lens, we expected the Sony to dominate in terms of image sharpness, and we have to admit it is more consistent across the image at wider apertures. Nevertheless the older Sigma 24–70 Art holds its own in this regard. Submit a valuation request and we'll provide guide prices with no delay.

Dust aside, the Sigma fared well in tough shooting conditions: poor light and moving subjects would have challenged many lesser lenses, and again, the 24mm over the Tamron's 28mm was appreciated.
