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.
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!
On the fotogenerell blog, the SIGMA 17-50mm f/2.8 EX DC OS HSM lens has often received a lot of positive feedback and in my opinion it is one of SIGMA’s evergreens. And this isn’t the case for no good reason – the all-round lens from SIGMA’s promising Contemporary series guarantees what the manufacturer promises. Compared to many lenses from SIGMA’s premium class, the Art series, the lens is very compact and light, which is why I prefer packing it in as a travel companion with the other heavier lenses. To me this lens has always been more than just a good backup – it has taken many of my favorite pictures.
There’s some exciting news for all Sony photographers among you! The MC-11 mount converter makes it possible to use interchangeable lenses with SIGMA SA-mounts and SIGMA EF-mounts on camera bodies with Sony E-mounts.
As you can certainly remember, the SIGMA Art 50-100mm f/1.8 DC HSM lens has been tested twice already under different conditions. Here comes the third practical test. First I tested the lens during a visit in the zoo, another time during a walk at night as I was searching for the colorful shining city lights I wanted to capture on my camera’s sensor.
Now I wanted to find out more about the image quality of the lens while shooting in the daylight in the early afternoon under a cloudy sky in a room with big windows. Moreover, in this article I will describe many advantages but also some minor drawbacks of the lens from my point of view and experience.
As many of you may have noticed I keep carrying two lenses with me most of the time. These two lenses have never disappointed me and they are a good choice at every opportunity. Of course, I’m talking about the SIGMA 50mm F1.4 DG HSM | Art and the SIGMA 24-105mm F4 DG OS HSM | Art. And for this lens review I decided to put the fairly reliable SIGMA 50mm F1.4 DG HSM | Art to the acid test. Therefore I’ve written two informative reviews. For all those among you who are technically experienced and who want to keep informed about all aspects of their lenses I can only recommend reading these reviews. I’ll briefly explain them and tell how well my lens fared.
TESTING THE AUTOFOCUS:
A very essential and meaningful test relates to the autofocus. Many lenses have minor or major errors with their autofocus right from the beginning. These errors can be deviations to the back or to the front, which is called back or front focus. On many cameras you can manually adjust the autofocus in the menu to a certain degree.
The autofocus can certainly be tested for every picture you take. You can check whether the focus is all right or too much to the front or to the back. But of course there’s also a more exact and standardized way of testing this. The company LensAlign produces equipment that facilitates these kinds of tests. For autofocus tests you shoot with an open aperture in order to check out the result in a much better way. The open aperture makes the level of sharpness smaller and allows you to define the focus point in a better way.
Some days ago SIGMA announced four new lenses on their website and on different company-owned social media pages. So before taking a closer look at these newcomers made of glass, I recently became interested in reviewing the classic that by now can’t be neglected anymore, the SIGMA Art 35mm f/1.4 DG HSM lens, in terms of autofocus and vignetting and with studio photography.
Architecture and desserts aren’t really two topics relating to each other at first sight. At least that’s what I’ve thought till I saw Dinara Kasko’s incredible desserts. The photos of her creations are shared all around the world, her Instagram account is booming. Some of her works may not look very appetizing in the beginning but rather nice to look at. But in her videos the artist shows you what the contents of her masterpieces actually is, making you quite hungry for some chocolate and other desserts.
In 2015 refugees were a big issue in Europe. In border areas in particular the agitation and the stream of people seeking refuge could be noticed. Hungary and the train station in Budapest were affected quite a lot as well. Thousands of refugees kept waiting there for transit permits, gathering on the spot. These events were covered by a lot of media and resulted in some impressive photographic creations. The works created by contemporary photographers are now displayed in Vienna’s Galerie Westlicht, showing images of the things that happened at the Austro-Hungarian border in autumn 2015.
