Sigma Zoom 28-200mm f/3.8-5.6 UC

This camera glass is a versatile photographic lens that can zoom from a wide-angle to a telephoto focal length. It has multiple lens elements that help to produce sharp and clear images. The lens coating helps to reduce glare and improve contrast. The build quality is decent, but not as sturdy as some high-end lenses. The aperture ranges from f/3.8 to f/5.6, which is good enough for most situations, but not ideal for low light photography. The autofocus is fast and accurate, but it also has a manual focus option for more precise control. The bokeh, or the quality of the out-of-focus areas, is decent, but not as smooth as some other lenses. The manufacturing time of this lens is not specified. There are alternative lenses available in the market that offer better image quality, but at a higher price point. Overall, this lens is a good option for those who want a versatile lens for their full-frame camera without breaking the bank.

Optical design

Has 7 aperture blades, mid-grade lenses usually have this amount of blades. Having rounded blades provides out of focus circle shape closer to a circle. Great choice mainly for good light conditions

Physical characteristics

With a lens filter diameter of 72 mm you are one step from the next standard filter size, buy step-up ring and bigger filter but you can chose from plenty options. 78 mm long, requires consideration if you want to carry in the camera bag. Weights 450 grams so plan ahead, carry only if really necessary.
