Sigma has been producing revolutionary lenses which has competed with the big guns: Canon, Nikon, and Zeiss. Sigma created quality and sharp lenses at significantly lower costs (though their newer lenses are creeping up a little in price). The Sigma 85 1.4 art and even more so the Sigma 135 1.8 art lenses have been long awaited by photographers.
I have used the Sigma 85 Art side by side with the Canon 85 1.2 L II lens. The Sigma 85 Art lens has been able to keep up with the bokeh monster. The Canon 5D Mark IV rejuvenated my Canon EF 85 1.2 LII and now I see that this lens is super sharp with great bokeh!
Meet Eri. Leighton Meester look-alike but great in her own right. Eri has great personality and huge potential to be a star. She is an actress and world-traveler at heart. She was wonderful to shoot with and gave us her own unique look. This was shot with an 85 1.4 Art lens at f1.4. The sharpness at f1.4 is incredible and the bokeh is definitely super nice as well.
The subject isolation and background blur is creamy. This was also shot at f1.4. Why do I shoot at 1.4? Because I like it! LoL. I like the character of the photos rendered with shallow depth of field. There is a time and place for shooting at smaller apertures but my style has been to shoot dramatic images.
Eri and the Sigma 135 @ f1.8. This one is obviously posted in BW. Subject isolation and bokeh are wonderful. The AF is fast and accurate right out the box. I bought the lens right before the shoot!
Meet Caroline. Model.
Also meet the new Sigma 135 1.8. The lens is super sharp. The bokeh rendering is quite good too. The next three photos were shot with the Sigma 135 Art lens. I know have a Sigma duo that will be when I shoot portraits. Its the Sigma 85 and 135 Art.
Meet Laura. Very young Paraguay model. Ginger and sweet. This was taken with the Sigma 85 1.4 at f1.4 with the 28 inch Speedbox/CL200x from Godox in Central Park. Sharpness is good and the bokeh looks very creamy.
