This medium telephoto macro lens offers a high level of optical performance and is ideal for both digital SLR and 35mm film SLR cameras.

The advent of digital SLR's requires optimum lens performance and therefore the very latest optical technology has been incorporated in the production of the new medium telephoto macro lens.
The 70mm focal length gives an equivalent field of view to our 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 both with natural light conditions or flash.

An easy to use 70mm medium telephoto macro lens

This lens has an equivalent field of view of a 105mm telephoto macro lens when used on digital SLR cameras with an APS-C size image sensor. The narrow angle of view is a great aid for simplifying backgrounds and the shallow depth of field aids composition. The greater working distance of this lens is very advantageous when taking pictures of flowers or the smaller things in our world that exist virtually unseen. 

Compensate for color aberration

A Special Low Dispersion (SLD) lens and two high refractive index SLD lenses provide excellent correction for all types of aberration- and produce an exceptional level of optical performance.

Reduce Ghosting and Flare

   

With Super Multi-Layer Coating     No Super Multi-Layer Coating

Sigma's super multi-layer lens coating reduces flare and ghosting, and helps create a natural color balance.

Floating Focus System

The floating focus system provides extremely high optical performance from infinity to 1:1 Macro.

Focus Limiter Switch

A 'Focus Limiter Switch' is incorporated in the lens, improving the speed and accuracy of autofocus by limiting the focus range between 25.7cm to 48cm and 55cm to infinity.

A screw-in lens hood

A screw-in lens hood is included for convenient use of circular polarizing filters. A screw-in lens hood (LH620-01) is included and is designed to accept a 77mm lens front cap.

MACRO 70mm F2.8 EX DG lens is awarded TIPA 2007 Best Expert Lens

The Sigma Macro 70mm F2.8 EX DG lens has been awarded the prestigious title of TIPA 2007 Best Expert Lens. TIPA said of the lens 'Sigma has used a very simple optical design, but has developed and included two decisive ingredients - a group of floating elements and the new SML multiple surface coating. The result is an excellent macro lens that's purpose-built for D-SLRs with APS-C sized sensors. And there's more: chromatic aberration is absent, distortion and vignetting are invisible, and the optics achieve a 1:1 reproduction ratio at the minimum focusing distance of 25cm. A great reference lens at an affordable price.'

‘There is no doubting the optical quality of this lens. Its one of the best macro lenses I have used. After picking one up as part of a bundle of second hand kit, I sold my Minolta AF 50mm and 100mm classic (1985-86) lenses and switched to using the Sigma. It was simply much sharper, and higher in contrast, without any tendency to flare or reflection patches.'

‘Can it produce an image that is worthy of the price? The simple answer here is yes. Out test charts reveal that it will produce a high level of sharpness across the frame. If you are thinking of investing in a macro lens for general-purpose use, this would certainly be a good choice. It is a great lens for digital SLR users, as its effective 105mm focal length proves very useful in the most surprising of situations, and as such the 70mm represents very good value indeed.'

   
What Digital Camera

‘Sigma EX lenses are always well constructed and this is no exception, with a metal mount, tough outer casing and good finish.’ ‘Image quality from the lens is great. It’s as sharp as a knife, with excellent contrast and resolution. At £339, this is a considerably cheaper option that optics from some of the other marques, and for those specialists among you, it certainly represents good value and a sound investment.’ ‘Sigma’s optics rarely fail to impress, and even those in the company’s premium range offer value for money compared to similar lenses. If macro is your thing, then the Sigma 70mm f/2.8 EX DG Macro could be just what you need.’
   
Ephotozine Ephotozine
‘As one of Sigma’s EX range, the build, handling and finish of this lens falls into the higher end of our expectations and this optic does very little to disappoint.’ ‘Sigma’s reputation for top quality prime macro lenses is upheld here with this 70mm offering. Designed to have a similar useful range as the very popular 105mm lens on a full frame camera, the optical performance more than matches up too. The lens proved to be sharp right from the outset at f/2.8 and stays that way right through…’
   
Professional Photographer Professional Photographer
‘Optically speaking, the Sigma performs really well. At f/22, images are crisp and sharp at the centre of the frame and at the edges. At larger apertures the in-focus parts of the picture are so sharp you need gloves to handle them, while the out of focus parts are soft and smooth. In fact, the Sigma continues to impress even wide open at f/2.8, where it performs superbly as a portrait lens.’

Designed to have a similar useful range as the very popular 105mm lens on a full frame camera, the optical performance more than matches up too. The lens proves to be sharp right from the outset at f/2.8…’ ‘Chromatic aberrations are so well controlled that similar, negligible readings were recorded throughout the aperture range and are as good at the edge as in the centre.’ ‘…the contrast delivered by this optic is excellent. Colour reproduction is neutral with no obvious casts, and the incidence of flare never reared its ugly head.’
   
British Journal of Photography British Journal of Photography
‘Not only can the 70mm Macro focus at very short object distances but also it renders out-of-focus areas with a very soft touch that is highly appropriate for natural subjects.’ ‘At this price, and with such a high level of performance, the 70mm Macro, which is available in Nikon, Canon, Sony, Pentax and Sigma mounts, is little short of remarkable.’
   
Photography Monthly Photography Monthly
‘Optically it is probably the best of Sigma’s already highly rated macro line-up, coming straight in with razor sharp, wide-open images. This lens is also suitable for use on full-frame sensors and 35mm cameras, so we think it will find its way into a number of photographers’ inventories.’
   
Digital Camera Buyer Digital Camera Buyer
This lens proves to be sharp right from the outset at f/2.8 and stays that way right through to between f/11 and f/16, where reciprocity starts to come in and degrade the image slightly. Even this is well controlled and there is no massive falloff as with some lenses.’ ‘We’ve harped on about Sigma’s DG coating in the past… well we’re doing the same here, as the contrast delivered by this optic is excellent. Colour reproduction is neutral with no obvious casts, and the incidence of flare never reared its ugly head.
   
Outdoor Photography Outdoor Photography
‘The matt black finish of EX lenses is renowned for being hardwearing, and when you first remove this lens from its packaging, it feels robust and well constructed.’ ‘The lens provided sharp results throughout its aperture range from f/2.8… I found distortion and chromatic aberrations undetectable. It’s a good addition to any outdoor photographer’s kit bag.’
   
Which Digital Camera Which Digital Camera
’Being an EX lens, it is also extremely well made with a reassuringly solid feel… The best thing, however, is its optical performance, which is strong right from the widest aperture. Even better, is the similarity between centre and edge performance; there is very little to choose between them at any aperture. Add to this the tight control over any optical gremlins, and you’ll soon be able to see why this lens gets our coveted Best Buy award.’
   
Amateur Photographer Amateur Photographer
’Like the other, it offers very high resolution with good contrast down to the higher frequencies. That quality is necessary for big or sectional enlargements from film or file. The 12.7 million pixels of the Canon 5D used in this test were fully able to exploit the lens. Its drawing too was excellent. With a street price of £304.99 (almost 20% cheaper than the Nikon lens’s SRP), and giving very fine image quality over the focus span from infinity to 1:1, this lens is worth considering.'
   
PhotoPlus PhotoPlus
’This is a good all-rounder. The 70mm focal length is equivalent to 112mm on most Canon D-SLRs, which is close to the popular 105mm focal length also popular with professional portrait photographers.’
   
Digital Photo Digital Photo
’…the 70mm Macro from Sigma offers a film equivalent of 105mm on a D-SLR with a 1.5x crop factor. The design is quite simple, with an uncluttered feel, with the focus distance indicator positioned on the barrel of the lens.’
   
Photoworld Photoworld
‘For distant subjects, the Sigma is equally as good optically and the 70mm length is ideal for portraits and studio product shots on the APS-C format.’
   
Digital SLR User Digital SLR User
‘The Sigma is the only lens in the test to include a focus limiter switch to restrict the range in which the lens will look for a subject. This is a useful feature that can save time and annoyance, especially when shooting close-up subjects. Wide open at f/2.8, the Sigma produces images that are on par with the Canon and slightly sharper than the Tamron.’
   
Digital Camera Essentials Digital Camera Essentials
‘So, the Sigma 70mm f2.8 Macro is one of the most versatile of its type. As well as shooting macro subjects to life-size (1:1 magnification) and slightly more with a APS-C sensor, as a short tele the 105mm equivalent focal length easily doubles as a portrait lens, allowing much tighter crops than a conventional portrait lens. Sigma has an excellent reputation for macro lenses, and yet the 70mm f2.8 EX DG Macro remains something of a hidden gem. If it’s sheer optical performance you value and you don’t want to break the bank, then this is a convincing alternative to the usual choices.’
   
Digital SLR Digital SLR
‘Optically the 70mm performs in almost exactly the same way as the much smaller 50mm lens, tending to put its best performance into the f/2.8 – f/11 section of the aperture range – for both macro and more distant photography – with f/11 being very sharp indeed.’
