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.

Sigma 10-20mm Lens Appearance & Feel. On first glance at the Sigma 10-20, this lens definitely meets the professional standards in terms of appearance and style. The standard black rubberized color scheme along with the white numbers and letters should fit any style of camera this lens will be used in conjunction with. The shiny gold ring adds a classy touch to an already professional look, although purists may not particularly like this addition. It comes with a two lens caps (front and rear), a lens hood (nice free addition) and a zippered carrying case that is nicely padded unlike other competitor models.

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.

3. Method of Acquisition – Did the reviewer get the lens for free or as a promotion thus making the review likely more positive or did the user pay top dollar, making the review a more valid and honest assessment. This can be tough to determine but many Sigma 10-20 review descriptions will include great depth.

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.
