A zoom lens is a type of camera lens that is offers the photographer a useful range of different focal lengths in a single lens. This is in comparison to a prime lens, which only offers a single focal length. A zoom lens allows for quick and easy re-framing of a scene while staying in the same physical position. Sigma offers a line of over 20 zoom lenses for DSLR photographers, ranging from wide angle zoom lenses, supertelephoto zoom lenses, and high-zoom ratio all-in-one lenses for both full-frame (DG) and APS-C (DC) digital cameras.
I had the opportunity to spend a few days in Michigan’s Upper Peninsula. I was doing some presentations in Kalamazoo […]
For this year’s gift guide, we asked our Sigma Pros to recommend some of their favorite gear. This crew of amazingly talented and hard-working photographers each focuses on a different specialty and has their own individual style, and they’ve all got their favorite Sigma gear. Check out these great reasons why our pros choose to use Sigma lenses and cameras.
Yellowstone National Park and Grand Teton National Park have to be the premier nature photography location in the lower 48 states. Subjects range from stunning and otherworldly landscapes to abundant free roaming wildlife. The best time to visit the parks is either in early spring (June) or my favorite time of year in late September to early October as the leaves start to change. The large summer crowds are gone and the park takes on a much slower pace, as it gets ready for the approaching winter. The image above is of the Teton Range just off the outside road. This image is at first light and I used a Singh-Ray, 3 stop, reverse graduated neutral density filter to help balance the foreground with the much lighter sky and mountain range.
Late every summer, nature photographers flock to the Pacific Northwest with the hope of capturing the majestic beauty of Mount Rainier and its gorgeous subalpine meadows. After much obsessive planning and conversations with photographers around Washington State, I was able to make my first trip to the region this year. My biggest concern was whether I would arrive on time to catch the peak wildflower bloom. The area experienced a warm spring and summer, and thus the wildflowers emerged earlier than expected. But, as luck would have it, that shouldn’t have been my primary worry.
Learning how and when to use different settings and options for image capture is one of the most important parts of becoming a stronger photographer. There’s no setting or camera function that’s going to be perfect for all situations, while is exactly why there are so many options. For example, every DSLR offers a couple variations on Autofocus for either a Single-shot or Continuously tracking autofocus.
Each has it strengths and purposes, and even with that, there’s still times when switching the lens to manual focus is the best way to ensure that your chosen subject and focal point is sharp in the image. In this piece, we’re going to look at three photos of seagulls to briefly explore and explain the reasons why to choose one type of AF or manual focus over the others.
Fall is my favorite time of year to take photographs, and I always push myself to get out and make the most of the brief window of brilliant color. I have spent the last week chasing fall foliage in the Pocono Mountains of Pennsylvania. This year, after taking the obvious shots of deep oranges and reds, I used my Sigma 15mm Fisheye lens to capture the forest from a different perspective.
Exploring the world through the Sigma 18-35mm F1.8 DC HSM | Art lens on the hunt for varying colors and textures, and levels sharpness and blur can create images that are at once new, and yet instantly recognizable. Close-up focusing on a pumpkin, for example, gives a shallow slice of sharpness, and lovely focus fall-off in a composition that’s pure seasonal color. And a single turning leaf backlit by the sun tells the story of autumn in a very different way than a sweeping vista of an entire hillside.
