Sep 24, 2010  Anyone got a link to a downloadable manual for a Sigma 105mm f/2.8 EX DG macro lens Thanks. What's new Latest activity Authors. Anyone got a link to a downloadable manual for a Sigma 105mm f/2.8 EX DG macro lens. As I happened to have this lens right next to me and my scanner was out.

The Sigma 105mm f/2.8 EX DG Macro Lens is - as you can discern from the name - Sigma's entry in the fixed short-telephoto focal length macro lens category. And in this case, Sigma means a true 1:1, close-up macro lens. Like most macro lenses (the Canon MP-E 65mm 1-5x Macro Lens excluded), this Sigma lens also can be used as a normal 105mm short telephoto lens.

3. DESCRIPTION Includes reviews for the new 'DG' digital SLR version of the lens. The Sigma 105mm f/2.8 EX Macro delivers superb, distortion-free images throughout its broad focus range, from infinity telephoto to 1:1 (life-size) macro, as close as 12.3' without accessories.
4. Dec 28, 2018  This Sigma Macro 105mm F2.8 EX DG is a large aperture medium macro lens ideal shooting The smaller things in our world that exist virtually unseen. A macro lens is one which will focus on a subject close enough to render it 'life-size' On the image plane in your camera.
5. OTHERS MACRO 105mm F2.8 EX DG OS HSM. HSM ensures a quiet and high speed AF as well as full-time manual focus override. This lens has a rounded 9 blades diaphragm which creates an attractive blur to the out of focus areas. In comparison to the Sigma 50mm and 70mm macro lenses, the main subjects can be defined with perfectly.

Opening the box and removing/opening the nice, well padded lens case reveals a very-nice-to-use sized, well-built lens. This size be visualized in the chart and comparison images below ..

Above, from left to right, are the Sigma 105mm f/2.8 EX DG Macro Lens, Tamron 90mm f/2.8 Di Macro Lens, Canon EF 100mm f/2.8 USM Macro Lens and Canon EF 24-70mm f/2.8 L USM Lens (for size comparison). The same lenses (sans Canon 24-70 L) are shown fully extended (1:1 macro focusing distance) below.

What is also obvious from the comparison photo above is that the Sigma 105 Macro extends - by up to 1.8' (42mm) - when focusing. Although not a big deal, when you are using a lens that extends while working with close subjects, care must be taken to not bring the lens in contact with those subjects. The relatively small 58mm filter threads do not rotate when extended or retracted.

What can also be seen in the above photo are magnification markings on the extended portion of the lens barrel. Two sets (one white, one yellow) are provided. Here is why .. The Sigma 105mm f/2.8 EX DG Macro Lens uses a not-nearly-as-nice as HSM or USM 2-step combination of a push/pull clutch and an AF/MF switch to select the desired focus mode - this is what Sigma calls their DF (Dual Focus) System. The focus ring is pushed forward or pulled backward to disengage/engage the manual focus mechanism. In the forward AF position, the focus ring turns freely but does nothing and AF does not cause the ring to turn. In the rear MF position, the manual focus mechanism is engaged. Back to the magnification markings - Because the focus ring moves in relation to the markings, 2 sets are needed. The white are for use during AF and the yellow are for use during MF. The picture below illustrates the Sigma DF System.

As can be seen in the above photo, the Sigma 105 Macro has a focus limit switch. Use the limit position to reduce focus hunting time by limiting the focus distance to 12.3' - 14.7' (313mm - 370mm) or 14.75' - 8 (400mm - 8). The minimum focus distance is 12.3' (313mm) which provides a working distance of 4.8' (122mm) from the end of the lens (without the hood in place).

The Sigma 105 Macro's AF system is definitely not one of its strengths - AF is slow, noisy and delivered a well-above-average number of OOF (Out of Focus) shots. I can often live with slow and noisy, but I find a high percentage of AF shots from this lens to be at least slightly out of focus even on a Canon 1-Series body using only the high-precision center focus point. If macro photography is your primary use for this lens, MF is probably what you care about most and the poor AF performance may not be an issue for you.

What may be the Sigma 105mm f/2.8 EX DG Macro Lens' biggest strength is image sharpness. This lens is sharp wide open and from corner to corner even on a full-frame body. This is the Sigma 105 attribute I hear touted the most - and rightfully so. However, this is a macro lens. Since DOF (Depth of Field) is very shallow at close distances, you will likely find yourself using this lens stopped down significantly. But maybe not to this lens' uniquely narrow minimum aperture of f/45 (f/32 with Nikon and Pentax mounts). Unfortunately, diffraction causes images to go soft beyond f/16 or f/22, so this extreme-minimum aperture is not helpful to me.

CA (Chromatic Aberration) is very well controlled. Vignetting is minimal. Distortion is negligible. Although it has 8 aperture blades, bokeh (quality of OOF areas) is only OK (not as smooth as the Canon 100mm Macro for example).

With their hoods in place, from left to right, are the Sigma 105mm f/2.8 EX DG Macro Lens, Tamron 90mm f/2.8 Di Macro Lens and Canon EF 100mm f/2.8 USM Macro Lens. The Sigma and Tamron lenses come with a hood included while the Canon hood is optional. As is obvious below, these macro lenses are much more similar in size when extended 100% at their maximum magnification of 1:1 (1.0x).

The Sigma 105 Macro's included lens hood is another unique attribute for this lens. First, it is a non-reversible, screw-in type. It screws into the 58mm filter threads - a relatively slow procedure. And because the 58mm threads are no longer available, the lens cap no longer fits - the hood must be removed to install the cap or a 58mm filter. Also unique is that the lens hood has threads to accept a 77mm filter. You can mount a 77mm filter such as a circular polarizer to the end of the filter where it is easy to reach. But, then the lens hood is not providing any shading for the filter. I suppose that buying a 77mm lens cap to mount on the lens hood would resolve the lens cap issue. But in the end, the front element of this lens is so far recessed, I'm inclined to simply forego the hood altogether on this lens.

The Sigma and Tamron macro lenses' objective elements are deeply recessed (better-protected, harder to clean) while the Canon's is not.

Since lens flare is what the hood is designed to help prevent (in addition to preventing damage), I'll go there next. The colorful circles of lens flare are basically non-existent in this lens. Unfortunately, veiling flare is significant. The result of having a bright light(s) in/near the frame is a washed-out/low contrast image.

The above near-center 100% sample crops were from the Sigma 105mm f/2.8 EX DG Macro Lens (left), Canon EF 100mm f/2.8 USM Macro Lens (center) and Tamron 90mm f/2.8 Di Macro Lens (right). All crops are from an un-moved, tripod-mounted Canon EOS-1Ds Mark II with identical settings for each photo (1/100, f/8, neutral contrast, AWB, mirror-lockup, 2-Second self-timer). Lens hoods were in place. All were shot within 4 minutes of each other at approximately 4:20 PM on Feb 24th - late on a very clear winter day - facing southeast. You can determine where the sun is by the direction of the shadows (far out of the picture). The Sigma, by virtue of its longer focal length, has less sky (brightness) in the picture (inset is a full-frame down-sized image from the 105). The difference in contrast is big. The lower contrast is not apparent in all of the images I've taken with this lens, but it does show in some.

The Sigma 105mm f/2.8 EX DG Macro Lens' focal length is slightly longer than the competing macro lenses. This variation does not make much difference from Canon's 100mm macro but is somewhat-noticeably longer than the Tamron 90mm macro. This focal length is a good compromise between working distance (and perspective), background diffusion and handholdability. Aside from macro work, this lens will make a nice full-frame portrait lens and a nice mid-telephoto on a 1.6x FOVCF body. A relatively wide f/2.8 aperture allows action stopping / handholdable shutter speeds at lower light levels.

I mentioned earlier that the Sigma 105 Macro is well built and I'll touch on that again. The barrel feels solid and the focus ring is smooth. Only a slight amount of play can be felt in the ring or the barrel - and only if more-than-normal force is applied. I still don't like Sigma's matte finish - I find is easy to get dirty and hard to get clean. Others like it a lot - it is a personal thing.

The Sigma 105 Macro is available in Canon (reviewed), Nikon, Sigma, Sony/Minolta, Pentax and Four-Thirds mounts. You should know that there are potential issues with third party lenses. Since Sigma reverse engineers (vs. licenses) manufacturer AF routines, there is always the possibility that a new body might not support an older third party lens. There are examples of this happening in the past. Sometimes a lens can be rechipped to be made compatible, sometimes not. Second, there is the risk of a problem that results in the lens and body manufacturers pointing blame at each other. However, Sigma USA's 4-year warranty is far superior to Canon's standard 1 year warranty (though many credit cards will double the Canon warranty for you).

You are likely considering one of the other available Macro lenses if you are researching the Sigma 105mm f/2.8 EX DG Macro Lens. The two that most directly compare have been mentioned above - The Canon EF 100mm f/2.8 USM Macro Lens and Tamron 90mm f/2.8 Di Macro Lens. The Sigma is at least as well built as the Canon and Tamron. It is similar in sharpness to the Canon and a slightly better than the Tamron. The Sigma has less vignetting than the Canon but is similar to the Tamron. It is also has the lowest price.

Even thought they are all 1:1 macro lenses, these lenses have different minimum working distances (MWD) at their 1:1 settings. The Canon, even though it has a slightly shorter focal length, has a longer working distance (6'/150mm) than the Sigma 105mm f/2.8 EX DG Macro Lens (4.8'/122mm). The Tamron has the shortest 1:1 working distance (3.8'/96.5mm).

To me, Canon's USM autofocus system is easily worth the price differential alone (even including the optional lens hood). Add to that the better flare performance, better bokeh, a fixed physical length .. and you have my opinion. My second choice would be more of a toss-up. The Tamron has better AF accuracy, better flare control and a one-step MF system.

All said, the Sigma 105mm f/2.8 EX DG Macro Lens is a really sharp and well-built lens for the price - a good value.

Sigma 100mm Macro

SLRgear Review
April 13, 2012
by Andrew Alexander

The Sigma 105mm EX DG OS HSM is an update of a venerable macro lens produced by Sigma for several years. The new lens is a complete overhaul of the design: a new layout of elements, optical stabilization and HSM focusing technology make up the large list of changes.

The Sigma 105mm EX DG OS HSM was designed as a full-frame lens, and on 'sub-frame' APS-C sensor-based camera bodies the lens provides an equivalent field of view of either 168mm (Canon) or 158mm (Nikon and others). Turn on onedrive windows 10. The lens is available in Canon, Nikon, Pentax, Sigma and Sony mounts.

The lens takes 62mm filters, ships with a round lens hood, and is available now for around $950.

Sharpness
The Sigma 105mm ƒ/2.8 EX DG OS HSM provides a very sharp image even wide open at ƒ/2.8, but for maximum sharpness you need to stop down to ƒ/5.6. There are traces of corner softness at ƒ/2.8, which settle down nicely at ƒ/4, and all but disappear at ƒ/5.6. Performance at ƒ/8 is more or less the same as ƒ/5.6 (though according to the numbers, just very slightly less sharp). Diffraction limiting sets in by ƒ/11, though you don't notice any practical impact on sharpness until ƒ/16, and even then, it's still very good. At ƒ/22 we begin to see some light softness across the frame.

The previous version of the lens could stop down as far as ƒ/45, but we noted extreme softness at this or the ƒ/32 setting - probably better that Sigma just removed these settings, as they didn't provide very useful results.

Chromatic Aberration
Chromatic aberration is kept very much in check with this lens; there is some to speak of in the corners when the lens is used on a full frame body (in this case, the Canon 1Ds mk III), but it isn't by any means excessive. Peeping at 100% crops, you'll note very light magenta fringing in the corners on the full-frame sample images - but it's very light indeed.

Shading ('Vignetting')
Mounted on the sub-frame Canon 7D, the Sigma 105mm ƒ/2.8 showed very little corner shading - just 1/3 EV darker in the corners, when set to ƒ/2.8. At any other settings, there is no light falloff.

Mounted on the full-frame Canon 1Ds mk III, there was a bit more falloff - more so when used wide open at ƒ/2.8. In this case the corners are over 3/4 darker than the center. At ƒ/4, the corners are just over 1/3 darker than the center. At smaller apertures, there is no problem with light falloff.

Sigma 105mm Macro Review

Distortion
The Sigma 105mm ƒ/2.8 EX DG OS HSM produces no meaningful distortion whatsoever, on either the sub-frame 7D or full-frame Canon 1Ds mkIII.

How To Use A Sigma 105mm Macro Lens

Autofocus Operation
The Sigma 105mm is a welcome advancement from the previous version, with its implementation of HSM focusing. Autofocus is moderately fast and near-silent, and results can be overridden by just turning the focusing ring. It took just over a second to go through the lens' focusing range - as a macro lens, there is a lot of focus travel. The front element does not turn during focusing, making life a little easier for polarizer users.

Macro
The Sigma 105mm provides excellent macro performance, offering full 1:1 (100%) macro reproduction, with a minimum close-focusing range of 31 cm (12 inches).

Build Quality and Handling
The Sigma 105mm ƒ/2.8 EX DG OS HSM is a fairly beefy optic, made lighter by its use of plastic components (725g, 26 oz). It's finished with Sigma's matte grey texture and offers a metal mount, and plastic 62mm filter threads. The lens is noted as having a splash-proof design.

The lens is a complete redesign of the previous version: it now features 11 lens groups, with 16 elements, of which one is a Special Low Dispersion (SLD) lens, another is a high refractive index SLD lens. There are now nine rounded diaphragm blades instead of eight straight ones, to improve bokeh performance. Focusing is by way of a floating focusing system that moves two different lens groups in the optical path. And to top it all off, Sigma has thrown in optical stabilization, very useful for when you don't want to bring a tripod into the field.

The lens offers a few control surfaces of note: in addition to the focusing ring, there is a small panel on the side of the lens which features a switch to enable or disable autofocus, and a switch to enable image stabilization in mode 1 or mode 2, or disable it completely. There is also a focus limiting switch, offering options of 30cm - 45cm, 45cm - infinity, and no limit (30cm - infinity).

The lens also provides excellent scales. There is a distance scale in feet and meters, as well as reproduction ratios as the lens is focused towards its close-focusing distance. However, there are no depth-of-field indicators, nor is there an infrared index marker.

The focusing ring for the lens is very nice - over an inch wide, composed of rubber with deep ribs. Manually focusing with the ring is stiffer than usual, but this is what you want for macro work so you don't disturb a carefully focused scene. There are no hard stops at the close or infinity ends - an increase in resistance lets you know there's no point to focusing further.

Sigma's OS (Optical Stabilization) technology features in this lens, which in our testing provides 2-2.5 stops of stabilization performance. It makes a slight whirring noise when it's activated. Our testing noted some poor performance in this system when used with a shutter speed of 1/60s; otherwise, it works as advertised.

The lens ships with a round lens hood, ribbed and painted a smooth black on the interior to reduce any flare. Sigma also includes the HA 680-01 subframe hood adapter, which is intended for use when the lens is used with (obviously) sub-frame cameras such as the 7D. Without the adapter, the hood adds 2 inches to the overall length of the lens - with the adapter, that goes up to around 4.

It's worth noting that there is no compatible tripod adapter for this lens. It is compatible with Sigma's 1.4x and 2x teleconverters.

Sigma Macro Lenses For Canon

Alternatives

Sigma 105mm ƒ/2.8 EX DG Macro ~$-
Now discontinued by Sigma, the original 105mm macro is a bit sharper than the new OS HSM version: results for CA and corner shading were also slightly better, too (though there was a slight trace of distortion).

Canon EF 100mm ƒ/2.8L Macro IS USM ~$1,000
Overall, the Sigma is a hair sharper than the Canon and produces less corner shading, but the Canon is more resistant to chromatic aberration. There isn't a significant price advantage for the Sigma in this case, and the offer more or less the same feature set.

Nikon 105mm ƒ/2.8G IF-ED AF-S VR Micro ~$1,000
The Nikon 105mm Micro was one of the first lenses we tested here at SLRgear - we don't even have a full-frame test for it. Based on the results from the DX sensor of the D200, it looks like the Sigma is slightly sharper, though the Nikon does show impressively low CA and almost no distortion.

Sigma 105mm F2.8 Macro

Pentax 100mm ƒ/2.8 Macro SMC P-FA ~$-
Possibly the sharpest of the macro lenses in this category, it's long since been discontinued and replaced by the P-D FA model which we have not yet tested. Results for CA, light falloff and distortion were all excellent, and also had an excellent feature set for macro work.

Sony 100mm ƒ/2.8 Macro ~$800
One of the better values in this category, the Sony offered good results for sharpness, though the Sigma is sharper at wider apertures. Stopped down, it was excellent. CA performance is all-around excellent, and it distorts very little.

Conclusion
Sigma has produced an excellent macro lens in the 105mm ƒ/2.8 EX DG OS HSM - it does away with an antiquated and confusing focusing system by using the HSM system, and offers optical stabilization. You'll want to be careful to avoid the 1/60 shutter speed when the OS system is in use, as it tends to do more harm than good.

The VFA target should give you a good idea of sharpness in the center and corners, as well as some idea of the extent of barrel or pincushion distortion and chromatic aberration, while the Still Life subject may help in judging contrast and color. We shoot both images using the default JPEG settings and manual white balance of our test bodies, so the images should be quite consistent from lens to lens.

Sigma 105mm f/2.8 EX DG OS HSM Macro User Reviews

• 9 out of 10 pointsand recommendedbyRJNaylor(4 reviews)
  none

  I've been shooting this lens for a few weeks and have pretty much left it on my second body (I was using a 50-200 or a 70-300 on it). Most people use it for macro but I really got it to extend the range of my Sigma 17-50 f/2.8 OS and it fills in beautifully for most things. Its low light focusing on my D7000 is fast and good. the OS is effective but you should give it a half second to settle. It is sharp at f/2.8 and really tack sharp at f/4 and good all way to f/16.
