Sigma 85mm f1.4 Art

The long awaited Sigma 85mm 1.4 Art is almost here. The lens accepts 86mm filters, and bigger and heavier than the competition. It comes after the very popular, high performance Sigma 35mm f/1.4 Art or the Sigma 18-35mm f/1.8 Art lenses.

Why is this lens is so awaited ? Because it is the classical short telephoto portrait focal length, when we can create very nice creamy background blur. Most professional photographers are portrait or wedding photographer, and this lens is one of their workhorse lenses (the others can be a 24-70 or 70-200mm). Before this lens Sigma released the also very interesting Sigma 50-100mm f/1.8 Art lens which can be also very interesting for portrait photographers.

The forest man of India

Click on the next image to see the video. This is just a jpg with no link.
I like trees very much, and I plant some trees as well single handedly. But the man in this story exceeds any imagination. He’s name is Jadav Payeng. See the story in more detail in the following video.

Jadav lives in the island of Majuli which once was covered with thick vegetation. Unfortunately the area become flat later, without trees or other vegetation. Jadav single-handedly built 1200 hectare forest himself, 37 years ago. He spent his last 30 years of life to plant this forest, which is now a home of 5 Tigers, included in the migratory route of Elephants and home of many creatures.
