Lens Review SIGMA 50mm F1.4 DG HSM | Art

Hey guys,

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.


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.

Photowalk with the Sigma 70-200 mm F2,8 EX DG OS HSM



Hey guys,

After my last photo walks and reviews led me through the streets of Marrakech, this week it was time again to take a tour through the local forests. Winter is about to fade away and the sun comes back for a few hours as the sunbeams warm our skin again. The last snow is about to melt and every now and then you can see little green leaves and grasses sprout.

SIGMA Art 50-100mm f/1.8 DC HSM Lens Review



After giving you a little impression of the SIGMA Art 50-100mmf/1.8 DC HSM lens on my photo tour in the zoo and the photos I was taking there, today you’ll get the extensive review of this new lens which I promised you. My descriptions and technical information will be highlighted with a lot of pictures I took in the zoo so you’ll get a proper insight into how things work out in practice. With the photos you’ll also receive the metadata to get a real impression. The camera I used was the Canon EOS 600D.

Berlin Wonderland


During the day there aren’t many hours left where you can sit in the sun and enjoy the daylight. At the beginning of this week, however, while strolling around Kreuzberg I found some time to shoot some photos in the evening atmosphere with my camera which was equipped with the SIGMA Art 35mm f/1.4 DG HSM on that day.

A lens in use – The SIGMA 35mm f/1.4 DG HSM in the street light and in the dark

As you could already see on this blog, the SIGMA 35mm f/1.4 DG HSM lens has been part of the equipment I take with me for quite some time now. I’ve tested its heart and its soul by studying diverse reports, professional reviews etc. and, of course, by taking photos myself under different conditions.

In order to finalize all the information on this particular lens I took pictures under very special light conditions for you – in artificial light in the dark.

Regarding the specs I need to say that I took all the pictures with an APS-C camera, the Canon EOS 600D. This means that I had to keep the ISO value as low as possible in order to take high quality pictures – so it was a real challenge for the optics of the lens.


Meta data

Aperture: 1.4
Shutter speed: 1/50
ISO: 400

Test: SIGMA 70-200mm F2,8 EX DG OS HSM

Hey guys,

I’ve decided to take a closer look at a rather old lens once again: the SIGMA 70-200mm F2.8 EX DG OS HSM. This lens is particularly useful for portrait, documentary but also for wildlife photography as well as for concerts and astrophotography.

Lens review:  18-300mm F3.5-6.3 DC Macro OS HSM 

Hey guys, a couple of days ago I borrowed the new SIGMA 18-300mm F3.5-6.3 Macro OS HSM lens to take a closer look at it. 🙂


Some specifications in brief:

  • It’s a lens suitable for APS-C cameras
  • With a focal length of 18-300mm wide-angle photos and telephotos can be shot
  • When you include the crop factor, this equals a total focal length of about 28-450mm
  • The aperture ranges from F3.5 to F6.3
  • The close-focus limit of the lens is 39cm

Sigma – Lens Review

Sigma 17-50mm f/2.8 EX DC OS HSM lens


 Sigma Objektiv 17-50mm f/2.8

The Sigma 17-50mm f/2.8 EX DC OS HSM lens has been part of my equipment for some months now, which is why I could test it in different situations and under various conditions. It belongs to Sigma’s standard zoom lenses and was made for crop cameras.

The lens is high quality manufactured. It weighs about half a kilo and is equipped with 17 elements in 13 groups. It has an uninterrupted wide aperture of 2.8. The smallest aperture is 22. The closest focusing distance of the lens is 28cm.


Why this particular lens?

I’ve chosen this particular focal length as I can cover many of the fields in which I like to move with it – travel photography, cover story, or street photography, portraits and landscape images. But it’s also perfectly suitable for architecture photography or for events. With its 17mm focal length the lens not only covers wide angle sections but with 30mm or 35mm, respectively, it also matches a standard lens with which you can take nice portrait photos. With its different focal lengths it’s also perfectly suitable for short trips, where I don’t want to carry lots of luggage and no heavy camera bag with interchangeable lenses.

A plus for brightness

Since I like taking pictures with my crop camera which quickly reaches its limits under bad light conditions in terms of image quality with higher ISO values, I wanted a lens that is able to slightly balance this factor with its high brightness. Taking pictures in rather dark rooms and with little illumination therefore is possible to a certain extent without losing a lot of quality. With correspondingly low shutter times under good light conditions motion blur can be avoided.

Wide aperture

I’m a very big fan of big depths of field in images, which can be created by a possibly wide aperture. With this lens it’s even possible to take high quality photos with a wide aperture. This factor makes the lens very attractive to me, as it can be handled very easily. You don’t need to bother about narrowing down the aperture to get sharp photos.


Autofocus and image stabilization

The lens contains optical image stabilization. Its purpose is to allow taking pictures 4 time levels longer without a tripod and without making the image blurred.

The autofocus, built into the lens is described as fast and noiseless by the manufacturer. However, when I tested the lens the autofocus turned out to be the only aspect I would critize. With a wide aperture or close-ups it sometimes takes a bit longer to focus the subject. In those cases I often switch to the manual focus which, however, makes shooting a sharp image much more challenging. But with a further closed aperture it works the way it should – quickly and reliably.



Despite the issue that sometimes occurs with the autofocus this lens has become one of my favorites. I like the different focal lengths very much and with them I take portraits as well as photos in the street or in nature. For me a bright lens is a MUST because I don’t want to miss out on taking photos even under less than optimal light conditions. And I have also often tested the optical image stabilization when I took pictures at night without using a tripod. So far I’ve always been totally happy with the results I got with this lens. Personally I enjoy working with it a lot.



Review: Sigma 150-600mm f/5-6.3 DG HSM Contemporary lens


The Sigma 150-600mm f/5-6.3 DG HSM is my second Contemporary lens. Except for belonging to the same lens series as the 17-70mm f/2.8-4 DC Macro OS HSM which I also have, they hardly have anything in common. It is large and heavy like every other full frame compatible telephoto lens with an extremely long focal length.

Review: Sigma 24mm f/1.4 DG HSM Art


The Sigma 24mm f/1.4 DG HSM Art is my third full frame compatible Art lens, and my fifth overall, and slowly but surely I’m having trouble keeping them apart. That is not only because of the very similar appearance of the DG Art lenses (24/1.4, 35/1.4 und 50/1.4), but also because of their very good image quality.
