So, in a more specific photography term, Art lenses, even with the widest openings, exhibit exceptional focal plane sharpness.
What does Art mean on Sigma lenses?
With this lens, Sigma is inaugurating a new line of interchangeable lenses: the “Art” line. This new line of lenses is designed to emphasize creative expression above compactness and multi-functionality, and you can expect sharply defined, high-contrast images with nice background bokeh.

Why are Sigma Art lenses so big?
It would seem that Sigma was intentionally producing oversized optics so that the softer edges of the image circle are farther away from the full frame sensor. Effectively, it’s like shooting with a full frame lens on an APS-C camera so that only the sharp center portion of the lens is being used.
What does DG HSM mean?
DG means it is designed with full-frame cameras in mind, so can be used on such bodies as Nikon D800 or Canon 5D Mark III (obviously you need an appropriate mount version for either system). The lens has Sigma’s ring-type ultrasonic autofocus motor (HSM) and optical image stabilization (OS).
What is DC lens?
“DC” stands for Defocus Control. DC allows the photographer to change the distortion characteristics of the lens so the “look” of the out-of-focus elements in the foreground or background can be changed to produce more pleasing photos, particularly portraits.
What are the 6 types of lenses?
Six Lens Types are shown below. Plano Convex. Plano Concave. Bi-Convex. Bi-Concave. Positive Meniscus. Negative Meniscus.
What are the two main types of lenses?
The two most common types of lenses are concave and convex lenses, which are illustrated below in Figure 1. A common bi-convex lens is considered a positive lens because it causes light rays to converge, or concentrate, to form a real image.
What is type of lens?

What are sharp lenses?
Generally, this means that you want the subject to be in focus with clear lines, crisp details, and no (unintended) blurring. It’s a combination of accurate focus, a static camera, and the properties of the lens you’re using.
Are Canon lenses better than Sigma?
No contest: the Sigma is sharper. Way sharper. Just like in studio, there isn’t really anything wrong with the results from the Canon, the Sigma is just better. Both lenses were wide open and the Sigma outperformed the Canon in sharpness even open further to f/1.4 over the Canon’s f/2.
Which lens is better Sigma or Nikon?
Sigma’s new Art series lenses are worth buying over nikon because they give you better detail, colors and more crisp image quality than Nikon. Moreover, Sigma lenses are cheaper as compared to nikon or canon lenses.
When would you use an art lens?
They are lenses created for images that give the sharpest details a photographer can possibly aim for. They also have higher apertures – f/1.4 to f/2.8. So, in a more specific photography term, Art lenses, even with the widest openings, exhibit exceptional focal plane sharpness.
How good are Sigma lenses?
Regarding image quality, images taken with the Sigma 50mm f/1.4 lens have excellent sharpness, contrast, and color transmission. There’s also no discernible distortion. In fact, the image quality easily beats out the Nikon 58mm f/1.4G and Canon 50mm f/1.2L. That’s quite a feat for a third-party lens!.
Do Sigma lenses have autofocus?
The technology employed is similar to that used in certain lenses made by other camera manufacturers. The benefits of HSM system are: virtually silent autofocus function, very quick responsive autofocus function. Sigma is the only independent lens maker offering lenses with this technology.
What is if in Tamron lens?
IF – Internal Focusing System. This is a feature that stops you from turning the focus ring while in auto-focus mode. LAH – Low Dispersion + Aspherical Lens. This hybrid lens element reduces aspherical and chromatic aberrations.
What is Sigma DC lens?

What is the difference between a DC lens and a is lens?
The IS stands for image stabilization. This allows you to take photos at slower shutter speeds without incurring motion blur. The IS version is older, but is considered better. The IS lens is good, the DC III is very poor and doesn’t do justice to a decent camera.
