Sigma 24-70 2.8 Art lens

By on July 18, 2017

Welcome to my new lens, my first Sigma Art Lens 24-70 2.8!

The Sigma 24-70mm F2.8 DG OS HSM Art is a fast standard zoom lens for full-frame Canon, Nikon and Sigma mounts. I’m using the Canon version. It has three special-low-dispersion and four aspherical elements, optical image stabilization, nine rounded aperture blades and an ultrasonic (HSM) focus motor. The lens is sealed against dust and moisture and supports 82mm filters

I haven’t shot with a model yet! Just one test shot, to see how it did in low light and wide open.

I shot using my 6D at Iso 2500 at 70mm at 2.8. It focused fast, noise not bad at all and it is tack sharp!

took a picture of the computer on my exercise bike.
