Most camera enthusiasts in today's internet era make their camera, lens and accessory purchases online. With the ease of access to these products and the competition inherent to the sale of cameras and camera accessories, users can easily shop around in a matter of minutes and find coupon codes to lessen the grand total for these purchases without ever leaving their homes. Leading up to the purchase, many buyers will search for a review for the product they intend to buy and see what advice other purchasers can offer to them prior to hitting the Buy button. While doing so can usually place the buyer with a increased sense of security, many fail to avoid some common mistakes when looking at reviews. For the purposes of this article, our focus will be on a Sigma 10-20mm Lens as an example. Below are the Top 5 Factors when looking at a Sigma 10-20 Review to determine its relevance for you.
The advancement of Sigma's own Special Low Dispersion glass (SLD) along with specially manufactured resins, polymers and surface treatments make this brand's lens products stand out from the rest. All Sigma lenses are designed in Tokyo, Japan and manufactured in Sigma's factory in Aizu, Japan. Distribution of all lenses is performed worldwide through its vast network of sales, distribution and service offices, making it one of the worldwide leaders in lens technology.
When photographers begin their search for a lens product review, the first thing that needs to be accounted for is the focal length for which they desire. Focal length in basic terms accounts for the magnification power of that lens with respect to the object being photographed. A lens with a shorter focal length has more optical power than a lens with a long focal length. In short, it brings the light rays to a focus in a shorter distance.
Sigma 10-20mm Lens Performance.
Once the camera is turned on, you get a much better feel of the Sigma 10-20mm quality. The lens auto focus is smooth as can be and ultra quiet for a wide angle lens, very important features in the professional photography setting to avoid distraction. More importantly, the HSM auto focus is extremely fast even in dim light conditions and the focusing very precise. One nice feature is that this is an internally focusing lens meaning that the act of focusing does not turn the manual focus ring. One thing that should be mentioned is the focus and zoom directions are the opposite of the Canon lenses so those who are normally Canon lens users will need to adjust to this minor feature. Again, the lens performance gets a 5 out of 5 stars.
Picture Sharpness. The Sharpness of the pictures taken with the Sigma 10-20 is very good and well above standards. When editing or magnifying the pictures, this model may not produce pictures quite as sharp as some of the extreme high end lenses from Nikon. Some of the photos could have been a little bit more defined in terms of the facial features but considering the vast price difference between this Sigma 10-20 lens and some of the Nikon models, sometimes as much as 50% of the cost, I wouldn't hesitate on going with the Sigma. Sharpness gets a 4.5 out of 5 stars due to the small amount of sharpness decline at the wide edges of the picture.
Picture Color and Saturation. Because the Sigma 10-20 has a 2 mm wider focal length than any of the Nikon competition, the mentality many of us make it terms of cropping post-shoot can be thrown out the window. The color on all of the pictures taken is vibrant and very rich without being too rich or deep. The contrast is also excellent for all picture types and settings, with outdoor shots being some of the best you can ask for. I have seen other reviews taking about cloud and mountain photographs being brilliant with this lens and I could only assume this would be the case with its great contrast feature. Maybe the best part of this camera is that with this wide-angle lens, you see pictures that you truly didn't even know were there. Quite an exciting experience for newbies. Color and saturation get a solid 5 out of 5 stars.
