We pledge to match the price on most products offered by UK based dealers that are selling officially imported or manufactured UK stock, with full manufacturer warranty and is authorised to do so by the relevant manufacturer.
Prior to the point of sale CVP will endeavour to match the price on most products subject (but not limited) to the following criteria:

Details of where you have found the cheaper item.
The prices shown are an estimate based on the purchase of a single item with nothing else in your basket. The prices and options do not include shipping regulations and duties which will be checked in the checkout process.
At CVP we always strive to get your order to you as quickly as possible, but in the interest of clarity please note that next day is defined as the next working day (ie: excluding weekends, UK bank holidays and public holidays).
Orders placed and security cleared before 14:00GMT where all items are in stock will normally be dispatched on the same business day for ultimate delivery according to the shipping method selected.
Where an item is not physically in stock, the actual delivery time will be extended by the lead time for the product in question. Shipping to the Channel Islands, Northern Ireland, Republic of Ireland and some remote UK postcodes are not next day but 2 working days.

Sigma have produced a remarkable lens thanks to their complete optical and structural redesign of the 18-250mm design. Its compact size is complemented in equal measure by its minimum focusing distance of just 35cm (a reproduction ratio of 1:2.9). It is also remarkably stable in varying temperatures because of its TSC (Thermally Stable Composite) construction.
The 18-250mm focal length range will cover all focal lengths for everyday photography - right from wide angle to long telephoto, and it is designed solely for APS-C sized sensors found in most DSLRs.
Other important features include a hard plated brass made bayonet mount and optical image stabilisation to aid handholding in low light or action shots and avoid blur from camera shake. A hyper sonic motor (HSM) ensures fast and quiet focusing, a rounded diaphragm provides natural looking defocus effects and the optics have Super Multi-Layer coatings to help reduce unwanted ghosting and flare effects.
|Lens Construction||16 Elements in 13 Groups|
|Angle of View (for SD1)||76.5 - 6.5 degrees|
|Number of Diaphragm Blades||7 Blades (Rounded diaphragm)|
|Minimum Focusing Distance||35cm / 13.8in.|
|Filter Size||Diameter 62mm|
|Dimensions||Diameter 73.5mm x Length 88.6mm / 2.9in. x 3.5in.|
Close-up capability is improved with the minimum focusing distance of 35cm throughout the entire zoom range, and maximum magnification ratio of 1:2.9. In APS-C size equivalent, macro photography with approximately 1:2 magnification ratio is possible. In addition, with this lens, the size and flaming of subjects can be adjusted by rotating a zoom ring, making macro photography easier than using fixed focal macro lens. For further convenience, the maximum magnification ratio at each focusing distance appears on the side of the lens barrel.
Optimization of the power arrangement by such as incorporating double-sided aspherical lenses, and reexamination of design, the filter diameter size is reduced. This compact size lens has the approximately 13x high zoom ratio with the filter size of diameter 62mm, and dimensions of diameter 73.5mm x Length 88.6mm. It ensures portability and overall ease of use, making it perfect for travel and leisure photography.
The new material "TSC (Thermally Stable Composite)", which has little contractility especially in temperature changes, as well as maintaining firmness, is incorporated into the lens barrel. Compared to Polycarbonate which is generally used, TSC has higher elasticity by approximately 25%. Since thermal shrinkage is low, it has high affinity to metal parts which contributes to high quality product manufacturing. It also contributes to the parts such as the zoom ring and scaling to be slimmer.
This lens incorporates brass made bayonet mount which has both high accuracy and solidity, same as the mount for camera body. The special treatment to reinforce the strength is applied on the surface to make it a high quality lens that is resistant for long-term use.
Sigma's own unique Optical Stabilizer (OS) function is incorporated. It offers effective correction of approximately 4 stops, which makes it possible to compensate camera shake even in macro range photography where a small blur can be easily identified. When photographing a moving subject such as motor sport, it automatically detects camera move, and offers effective correction for camera shake.
NB. The OS effectiveness will gradually decrease as the shooting distance becomes shorter.
SLD (Special Low Dispersion) glass element offers excellent correction of color aberration. Three aspherical lenses including double-sided aspherical lens together with the latest design, prevent and correct all types of aberrations including astigmatism, achieving high quality images throughout the entire zoom range.
From an early stage, flare and ghosting are thoroughly measured to establish the design which is resistant to strong incident light such as backlight. Super Multi-Layer Coating reduces flare and ghosting, and provides sharp and high contrast images even in backlit conditions. Supplied petal-type hood can be attached to block out extraneous light which has a harmful influence on rendering of the lens, and prevent internal reflections to occur.
The HSM (Hyper Sonic Motor) ensures fast and quiet auto-focusing.
The rounded 7 blade diaphragm creates an attractive blur to the out of focus areas.
A lovely general purpose lens to travel with, giving me macro and tele-photo with clarity and not too much weight.
