Key Features: Sigma 105mm f/2.8 Macro EX DG OS HSM
High performance, large aperture medium telephoto macro lens with OS (Optical Stabilizer).
SLD glass provides good control of aberration and the floating inner focus system ensures high rendering throughout the focusing range. By using Sigma's APO Tele Converter, it is possible to take photos at greater than 1:1 magnification. 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.
Large aperture medium telephoto macro lens
This medium telephoto macro lens allows you to maintain an appropriate distance from subjects while still getting close up photos. Since the working distance at its closest focusing position is 142mm, shadows of the lens and camera will not affect photography making it suitable for taking photos of subjects, such as flowers, under natural lighting conditions. In comparison to the Sigma 50mm and 70mm macro lenses, the main subjects can be defined with perfectly smooth and blurred backgrounds.
High rendering performance
The lens power layout produces excellent optical performance. High refractive index SLD (Special Low Dispersion) glass corrects chromatic aberration, spherical aberration and field curvature. It ensures high rendering performance at all shooting distances. The Super Multi-Layer Coating reduces flare and ghosting, maintaining quality images with high contrast.
Handheld photography with ease
Sigma's OS (Optical Stabilizer) system offers effective correction of approximately 4 stops. As the stabilisation effect is visible through the viewfinder, it aids composition and accurate focusing.
* The OS effectiveness will gradually decrease as the shooting distance becomes shorter.
Floating inner focusing
This lens incorporates floating inner focusing which moves two lens groups separately. This minimizes aberrations which occur as shooting distance changes, and enables stable rendering of the image from infinity to 1:1 magnification. This also corrects image distortion, especially when taking close-up pictures. Since focusing does not change its overall length, this lens is easy to hold and use.
Hyper Sonic Motor
HSM (Hyper Sonic Motor) provides quiet and high speed AF. It is also possible to use full-time manual focus, even if the lens is set to autofocus.
This lens has a rounded 9 blade diaphragm which creates an attractive blur to the out of focus areas. This also creates smooth, rounded out of focus highlights when taking photos which have a strong light source in the background such as lights shining on the surface of water.
APO Tele converters
This lens is compatible with Sigma's APO TELE CONVERTERS. With APO TELE CONVERTER 1.4x EX DG, it can be used as 147mm F/4 AF* telephoto macro lens, and APO TELE CONVERTER 2x EX DG as 210mm F/5.6 MF telephoto macro lens. This allows a greater working distance while still achieving 1:1 macro magnification.
* AF does not work from 0.45m close up photography.
Sigma Lens Terminology
Sigma’s DG lenses are designed for cameras with a full-frame sensor, but cameras with a cropped sensor can also take these lenses. These are large-aperture lenses with wide angles and short minimum focusing distances. With an abundance of peripheral illumination, they are ideal lenses for Digital SLR Cameras whilst retaining suitability for traditional 35mm SLRs.
OS (Optical Stabilizer)
This function utilises a built-in mechanism that compensates for camera shake. It dramatically expands photographic possibilities by alleviating camera movement when shooting hand held.
The exterior of this lens is EX-finished to denote the superior build and optical quality, and to enhance its appearance.
HSM (Hyper-Sonic Motor)
This lens uses a motor driven by ultrasonic waves to provide a quiet, high speed AF.

Are you eligible for finance?
Applicants must be:
Aged 18 years or older from the application date
In permanent UK residence for a minimum of three years
Fulfil at least one of the following employment criteria:
In regular, permanent employment.
Retired from regular employment - With a minimum age of 50.

Note: All applicants will be subject to a credit reference check by the lender.
Credit is subject to application and status. Warehouse Express Ltd trading as Wex Photographic act as credit broker and not the lender. Barclays Partner Finance act as the lender.
Can I repay early? If so how?
No repayments are scheduled in the initial six-month deferral period. However, it is possible to pay off the loan, either by way of a lump sum or in smaller amounts. If the loan is fully repaid within the six-month deferral period, then no interest is payable, but a £29.00 early-settlement will be incurred. Such repayments may be made to Barclays Partner Finance by cheque, debit card or standing order. Unfortunately it is not possible to set up a direct debit within the deferral period. Further information on how to make such repayments will be set out in the loan agreement pack provided by Barclays Partner Finance.
What happens if I don't repay within the first six months (deferral period)?
Following the six month deferral period, Barclays Partner Finance will initiate a monthly direct debit payment for the remaining duration of the loan. Interest will be charged at a rate of 19.9% APR on outstanding balances (backdated to the first date of the loan). Late payment penalties and early repayment charges will apply from this point. Barclays Partner Finance will send a reminder letter approximately one month before the six month deferral period is due to elapse. Note: If you chose to spread the cost and pay monthly, interest is charged from the start of the loan, not from the start of the repayment period.
What will I receive from the finance provider (lender)?
Barclays Partner Finance will send a loan agreement pack approximately four weeks after delivery of the goods, confirming that the account has been activated and, from this point, it is possible to make repayments against the loan.
