A few days ago SIGMA published new firmware updates for lenses. The four new editions are models with Canon EF and Sigma SA mounts. The updates are said to have led to improvements concerning the auto-focus as well as to a reduction of the operating noise of the shutter lamellae. Sigma has published firmware updates for four of its lenses with Canon EF and three models with Sigma SA mounts.
There are updates for the following lenses, whereas the first three have been improved for SA and EF bayonet mounts and the 24-105mm lens can be downloaded for Canon EF bayonet mounts only.
17-70mm F2.8-4 DC MACRO OS HSM
18-200mm F3.5-6.3 DC MACRO OS HSM
18-300mm F3.5-6.3 DC MACRO OS HSM
24-105mm F4 DG OS HSM
SIGMA promises an improved AF performance in particular in connection with the lens adapter MC-11, which I’ve already tested for you recently . In connection with Sigma’s sd Quattro cameras the speed of the auto-focus, in particular, is said to have been enhanced.
Another improvement will make all the video enthusiasts among you very happy! With Canon EF mounts, AF exactitude in the LiveView and video modes are said to have been upgraded. Besides that, the operating noise of the shutter lamellae in the video mode was reduced, which has improved the sound while recording videos.
There’s also an update available for the Adapter MC-11. It enables the use of the upgraded lenses.
Not so long ago I could hold the SIGMA 24-70mm f/2.8 lens in my hands. Of course, I couldn’t resist, grabbed it and walked right to the nearest park. The evening sun was stroking the lush green of the summer trees and the meadows and long-necked colorful flowers were blowing in the soft breeze.
Photos can be a powerful tool. Both in a negative and in a positive way. Photos show reality the way it has happened, objectively and truthfully. At least that’s been the opinion of most people for a long period of time.
Nowadays one has become a bit more skeptical concerning photos and videos. We know that professionals can manipulate and also exploit almost every detail of an image with Photoshop and other programs and we’re aware that images nowadays can also be willingly used to serve certain purposes.
However, photos can also cause something positive. They can make people think, inspire and delight them. They can also create social changes, reforms and revolutions.
One guy who has changed the situations of many people in a positive way with his pictures is Jacob Riis.
My urge to experience some adventures and escape from our everyday lives is constantly increasing the more work I have. And that’s what I felt a couple of days ago. The sun was shining, it was one of the wonderful warm days. I grabbed my Canon 5D Mark III and the appropriate equipment of lenses for a very particular purpose – that is, for Urban Exploring.
Today it was time again to grab my camera in spite of the cold weather and dedicate myself to one of my absolutely favorite pastimes. Of course, I’m talking about a photo walk.
The 50mm F1.4 DG HSM | Art is a lens that’s being discussed a lot, both on fotogenerell and in all other media. Besides the 35mm Art lens there’s probably not another lens that’s as popular and so much liked and cherished as this SIGMA lens. It’s not without a reason that you can find SIGMA’s ART series in the camera bags of professionals.
When can you use which lens? The SIGMA 35mm DG f/1.4 Art has already been presented to you. Today, I’d like to take a closer look on the SIGMA 50mm DG HSM f/1.4in a comparison to the 35mm fixed focal length. What’s better than a perfect comparison with a tour on the market and all the nice colors? I’ll take you along!
Some consider it to be art, others call it vandalism. I definitely belong to the first group. At least when it’s not just scrabbling but when there’s a message behind the whole image, when some style or at least some effort can be recognized. I’m talking about street art.
Martha Cooper is almost a celebrity in the street art and graffiti scene – and this although she doesn’t even belong to the Urban Artists. The 77-year-old woman has been taking photos since her childhood. She claims that she always knew that photography is her calling. In the 1970s she achieved what many can only dream of: She worked as a photographer for a renowned newspaper. One morning, on her way to work, she noticed the New Yorkan trains decorated with graffiti and she began to take pictures of them. Her fascination with the New York behind the scenes, the underground and the visible decay of the city increased every day and finally she quit her job at The New York Post. In the 1970s, New York was going through an economic and mainly a social crisis. Large parts of the population were almost left to themselves with only few perspectives. Martha thinks that the “make something out of nothing” typical of the graffiti and hip hop culture at that time fascinated her in particular.
Colors, shapes, structures and contrasts have always fascinated me. Before I held my first camera in my hands at the age of seven, I spent a great part of my time painting, drawing and modeling clay. Even today I try to capture the magical interplay of an endless series of colors in my pictures.
The work from Ukraine-born New Yorkan photographer Alex Nero is a mix of chemistry, painting and digital photography. Bold colors, mystical shapes and breathtaking contrasts make his pictures compelling pieces of art that will completely spellbind you.
It was these photos – soft blue tones, ice and water, the Arctic – about which I’ve recently happened to come across again. Photographs taken by a New Yorkan photographer and environmental activist called Diane Tuft . Since 1998 she’s been reporting on the beauty and fragility of our planet and environment with her camera. Before that she’d rather been focusing on multimedia.
