Sigma 70mm f/2.8 overview

  • 1Description

The Sigma Macro 70mm f/2.8 EX DG Lens is a medium telephoto macro lens which is ideal for both digital and 35mm film SLR cameras. The 70mm focal length gives an equivalent field of view to the popular 105mm macro lens when used on digital SLR cameras with an APS-C size image sensor.

The design of this lens makes it suitable for taking pictures in all situations, from infinity to 1:1 macro, both with natural light conditions or flash.

Note: Similar to Nikon G lenses, this lens does not have an aperture ring. G-type Nikkor lenses are fully compatible with the F5, F100, N80, N65, N60, N50, N4004-series, PRONEA 6i, PRONEA S, D100 and D1-series (or any newer model) cameras. For the F4, N90-series, N70, N8008-series and N6006 cameras, only programmed auto or shutter-priority auto exposure mode can be used.
AF not supported by D40 and D60 cameras.

A Special Low Dispersion (SLD) lens and two high refractive index SLD lenses provide correction for all types of aberrations and produce an exceptional level of optical performance.
Sigma's super multi-layer lens coating reduces flare and ghosting, and helps create a natural color balance.
The floating focus system provides extremely high optical performance from infinity to 1:1 Macro.
A Focus Limiter Switch in incorporated on the lens, improving the speed and accuracy of autofocus by limiting the focus range.

    Sigma 70mm f/2.8 reviews

    70mm f/2.8 EX DG Macro AF Lens for Nikon AF is rated 5.0 out of 5 by 11.
    Rated 5 out of 5 by from Great lens I've had this lens for years....I can't even remember when I bought it. It is one of my two favorites when I need a sharp and shallow DOF shot - the other being Nikon's new 85mm f1.4 which I've had for a only few months now. The Sigma is super sharp making it a nice portrait lens or macro. I have a D300. It's a little slow to focus and if you decide to try your luck with autofocus when taking macro shots, you will likely find that it hunts a bit but I don't normally rely on AF when shooting macro shots so the hunting is not an issue. I would not trade the sharpness for a lens that focused a little faster or hunted a little less. When I'm taking non-macro shots in all but dim light it focuses just fine.

    Rated 5 out of 5 by from solid choice I was looking for a duel purpose macro/portrait lens and this fits the bill. I already own another Sigma lens and the quality of the glass and construction provided me the confidence that the 70 mm f/2.8 would meet my expectations. I am in the process of upgrading from my old d40 to my new d700. For d40 owners, autofocus is not operational (certainly not a big deal for macro or portrait work). This lens generates stunning shots, on both platforms, with crisp clarity for primary subject and very nice bokeh. While I've just gotten this lens, I can see now that this will probably become my workhorse. As alluded to above, I've been quite pleased with Sigma glass. When you ratio the end product quality over the price, it's hard to beat.

    Rated 5 out of 5 by from Great Alternative I mostly use this lens for portraits. I'd been using a 50mm on my Nikon D7000, which gave me an effective length (FOV) of 75mm, but I wanted something a little longer. This Sigma 70mm (effective 105mm) was just the ticket.One review site said it is one of the sharpest lenses they have ever tested, and they weren't kidding. Be prepared to do some post processsing on older women's faces. But you get sharp as sharp gets, eyes and hair, etc.; and the color and contrast are wonderful. Bokeh is lovely, too!Build quality is excellent, and the lens handles quite well. Put the focus limit switch on to speed up non-macro focussing. I could not be happier with my purchase.And of course, B&H did their normal, fast shipping; and it provides me comfort to know they are behind the sale.

    Rated 5 out of 5 by from One of the top 3 sharpest lens for Nikon This lens, produces the most amazing, most sharp pictures I've ever done with my Nikon cameras. Downsides: No internal focus motor, can't be used on D3100/D3200/D5100 (it can but in manual mode) No focus override (once in AF mode, you can't turn the focus barrel) Sometimes when focused to infinity, can't refocus back (on the D7000) Slow compared to all the above mentioned, but not substantially Metal hood, can't be reverse mounted 10/10 image quality (at 2.8!!) 8/10 built quality and handling 8.5/10 price (for a new lens, locally, inc tax) 6/10 focusing speed 10/10 Macro capabilty Overall, if you are looking after a good prime for general use, and a superb macro lens, get this lens, full no reservations recommendation. This is an FX lens, which on a DX camera gives a 105mm fov.

    Rated 5 out of 5 by from Quality At A Value Price I am using this 70mm Sigma EX DG primarily as a Macro lens on my Nikon D80, getting the net effect of a 105mm f/2.8 lens on the D80's APS-C sensor. The build is excellent. The EX quality is evident. Smooth, quick AF. Only negative is the screw-on lens hood...when not on camera you have to find a place to secure it, versus reversing and stowing on the lens itself like Sigma offers on its longer FL lenses...and Nikon offers on all lenses.

    Rated 5 out of 5 by from I use this on my Nikon D90 - LOVE IT This lens is absolutely amazing for portraits. It has served me well for over 5 years. So far, I have no problems with it. After my friends see how clear my pictures turned out, they all want this lens too.

    Rated 5 out of 5 by from Exactly as described, sharp.. I needed a sharp no-nonsense lens for a large series of industrial close-ups, and my criteria was sharpness and virtually no linear distortions. The Lens performs well.

    Rated 5 out of 5 by from Terrific Lens.. at a reasonable price This was a perfect match for this full-time Pro photographer. I needed a longer macro to get me near to 1:1 repro ratio with a further camera-subject distance. I bought it specifically to shoot a jewelery catalogue; but have found that the lens is a superb portrait lens as well as a top-notch medium fast (2.8)general use telephoto. This is my 3rd Sigma lens for my Nikon bodies. I've been more and more impressed with the optics/color rendition/design/construction of Sigma lenses. I initially bought these as back-ups, but use them more and more as #1 lenses. My only minor complaints are 1. The inability to reverse the lens shade and store it on the lens. This isn't a problem when the lens is off the camera (the shade stores nicely on the back of the lens); but is a minor problem when I want to store the lens on the camera. I do love that the provided shade is metal; and don't mind that it's a screw-on (not snap-on) 2. No auto focus/manual switch on the lens. Apparently this is true only on the Nikon version. Odd because all of my other Sigma/Nikon lenses have the switch. The camera control switch works very well if I need to focus manually. Nothing in the instructions to explain this; but easy enough to figure out. Very glad I bought this lens
