No. All our lens hoods are matched exactly to the lens they are supplied with.

Sigma lenses do come with a 1 year international warranty, however, the warranty is only honoured if VAT and duty have been paid on importation into the UK, otherwise it is an illegal import. Once these taxes have been taken into account, our customers usually find it better value to buy an official UK imported …

Unlike most cameras, the Nikon D40x does not have an auto focus motor built into the camera. Therefore, auto focus will only work with our HSM lenses as these have a motor built into the lens.

We produce a range of lenses in the Four Thirds fit. For details of these, click here.

The filter used in the 300mm f/2.8, 500mm f/4.5 and 800mm f/5.6 lenses have a 46mm filter size and there is no problem if you attach the filters of the other brands. However, if the thickness of the filter is over 5mm then you cannot attach this filter to its holder. In the case of …

The image of the subject, which is taken by both lenses, will have same magnification, however the size of backgrounds will be different. The picture, which is taken by 50mm/f2.8 EX Macro Lens, will have wider background if compared with the 105/f2.8 Macro Lens. Further, lens to subject distance will be different for making life …

First, set the zoom control to its maximum telephoto position. Then, slide the Macro Switch to the “Macro” position. Now the focus ring can turn from infinity to macro range. (The macro switch cannot be changed to the “Macro” position if the zoom ring is set to other than the maximum telephoto setting.) While the …

This is the distance from the film plane/image sensor to the subject. Many people assume it is the distance from the front of the lens however it is measured from the film plane. The shorter the Minimum Focusing Distance, the closer you can focus on the subject.

The vibration caused by the firing of the shutter and the movement of the mirror is transferred to the tripod. The characteristics of these movements are different to those experienced during hand held photography and the OS system cannot compensate for them. If you wish to use a tripod, please switch off the OS function.

The AF control system for some Nikon Cameras does not work with HSM lenses. Sigma’s HSM lenses have full compatibility with F5, F4 series, F100, F90/N90, F90X/N90S, F80/N80 F70/N70, u/F65/N65,Pronea 600 and Pronea S. With other Nikon cameras, Sigma’s HSM version lenses can be only used in manual focusing mode.

The lens you received has a serial number which has not been issued by Sigma’s factory in Japan. It appears that the lens you received is a “Grey Market” lens, and has been tampered with having its serial number changed. This would explain why you received no factory warranty card with the lens; the serial …

Due to the ultra wide angle shooting capabilities of lenses such as the 15mm, front filter use simply is not possible. It would damage the front element of the lens and cause heavy vignetting on the images. Gelatine filters are available from the following website: http://www.galvoptics.co.uk.

Each of the Sigma prime macro lenses offer up to 1:1 (Life-size) reproduction images, but at different working distances. For example, the 50mm lens provides the shortest working distance and the 180mm lens the longest working distance. Therefore, if you are looking to do copy or reproduction work, the 50mm is likely to be your …

All Sigma products, lenses, cameras and flash units are manufactured exclusively by Sigma in Sigma’s own factory in Aizu, Japan. No Sigma Corporation product – lens, camera or flash – is manufactured outside of Japan. This is very unusual these days, as most companies have at least some of their products produced outside of Japan …

OS lenses do make a soft noise upon start up. This noise emits whilst the OS system is setting into position. Once the OS is set, generally after one or two seconds, the noise will stop. This is completely normal for OS lenses.

W indicates wide focal length and T indicates telephoto. For example on a 28-80mm zoom lens W is equal to 28mm and T is corresponding to 80mm. Depth of field region can be determined by combination of depth of field scale and distance scale. The depth of field scale is printed on depth of field …

With conventional auto-focusing, auto-focus is driven by electromagnetic force of a DC-motor, gear and shaft mechanism. However, Ultrasonic Oscillation Energy operates the HSM lens and creates high-torque drive. Since this motor has no reduction gears, it has much quicker response to start and stop compared to DC- motor lenses. HSM system has virtually silent auto …

The major difference between these two lenses is the optical performance. The DG model features a more conventional, achromatic optical design and uses one element of Special Low Dispersion glass (SLD). Its sharpness and contrast are rated very highly, however it is not quite as good as the APO model, which uses an apochromatic optical …

Our tele-converters are matched to work with a few Sigma EX telephoto lenses and are therefore not compatible with all our lenses. For a full chart of compatible lenses, click here.

Sigma produces lenses with exclusive fixed mount systems; therefore it is not possible to change the mount of a majority of Sigma lenses. However with the new Mount Conversion Service, any of the Global Vision Lenses can be converted to a different mount system. More details can be found in the Mount Conversion Service information …

It is normal for this lens to make a slight buzzing noise. Please refer to the lens’ instruction leaflet for further details.

Each abbreviation has its own meaning and is an important part of the lens’ construction and design. For detailed descriptions of each abbreviation, please click here to visit the lens technology page on this website.

The designation DG indicates that the lens has been optimised for digital SLRs but is equally compatible with film SLR cameras. These will work on digital SLRs with a small (APS-C size) image sensor, digital SLRs with a full frame sensor and film SLRs. DC lenses are designed specifically for digital SLRs with the small, …
