The first time I used this lens back in May 2016 I fell in love with it for a couple of reasons. The focal length, 20mm, is a real sweet spot for both landscape photographers and night photographers as well. Fast 1.4 f stop. While we don’t tend to normally shoot at the widest f stop on a lens having a 1.4 really gives you some breathing room when it comes to exposure and sharpness. Let’s say you are doing night photography and you have a Rokinon 14 2.8 and you have a Sigma 20mm 1.4 Art Lens. The scene you are shooting is very dark with only minimal light. with the Rokinon you may have your camera set at 6400ISO for 30 seconds in order to get a good exposure but you find that your images are coming out fairly noisy at that ISO. With the Sigma 20mm you could shoot at F 1.4 at ISO 1600 for 30 seconds and get the same exposure value. Now while the sigma does offer an amazing 1.4 f stop, it’s rare that I would shoot at that for my work. Generally speaking the widest f stop on any lens will also give you the least quality. Shooting at 1.4 would be very fun for some up close daytime stuff where you are feeling a bit artistic or even at night when you don’t mind of the stars are out of focus and you just want to focus on your foreground subject… I have found that the real sweet spot for this lens is right at F2 or F2.2 depending on what I am shooting and the available light. Which is still quite a bit faster than a 2.8 lens. In the images I will be sharing with you, you will be able to see the data for the lens used. I shoot this lens between 1.8 and 2.8 when I am shooting at night. Enough talk, let’s see what I am talking about. The first set of images are multi shot panoramic images I captured with the Sigma 20mm. 1.4. Because of the extremely low distortion it makes stitching the images very easy.
This next set of images were taken later in the Summer when the Milky Way rising up overhead instead of low on the horizon. These are vertical panoramas all taken with the Sigma 20mm 1.4 lens.
Each of the images below were created using either multiple exposures or single long exposures.
The final set of images I would like to share are just simple single exposure, shorter exposures and general photographs taken with the wonderful Sigma 20mm 1.4
