Sigma Art 35mm Real World Review
Sometimes I like to challenge myself by grabbing only one lens, throwing it on my camera body, and doing the best I can with it. I have been enjoying fixed focal length prime lenses. It forces me to move my feet to "zoom" and leads to different perspectives that I wouldn't otherwise get with a zoom lens. I put this lens on my Nikon D750 and took it to the New England Aquarium in Boston, MA.
The 35mm focal length worked great for the tighter spaces in the aquarium. When the crowds surrounded us around the touch tank, I was able to be shoulder to shoulder with my subject, but still able to compose an effective image.
With the f/1.4 maximum aperture, the lens lets in a lot of light in low light settings. This allows you to use a faster shutter speed and lower ISO, leading to less handshake blur and sensor noise. Be careful with the wide open aperture. The depth of view is razor sharp and it is easy to miss focus on your subject. I also recommend using your camera's fine tune adjustment option to dial in your prime lenses. Both of my Sigma Art prime lenses were front focusing and needed adjustment.
I left my flash at home because I knew that it would only reflect off the glass and blow out part of the image. All of these images were taken with the provided light and handheld. The focus was right where I needed it and the exposure came out right where I needed it. These images were edited using Adobe Lightroom. I did use my on camera flash for one image of my wife and daughter in front of the turtle only so they weren't completely silhouetted against the bright background.
Overall, I have really enjoyed this lens as an environmental portrait and walk around lens. The focal length gives you some room to get close to your subject and create some interesting compositions. Combine that with the shallow depth of view and you have an amazing tool for your camera bag.
