What is a Zoom Lens? And why and when to choose a Zoom Lens?

Sigma offers a great variety of zoom lenses. (Lenses are not shown to scale in this display.)

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.

A Shared Connection: The Bryant Family Shares a Love of Photography

Bailey Bryant, age nine, makes a photo with one of the two Sigma 150-500mm F5-6.3 lenses his family owns near their home in Florida.

The love of photography is something that is oftentimes shared and passed down through the generations of a family. Ask a photographer where they first caught the photo bug, and there’s a good chance that a father, uncle, aunt or mother originally sparked that interest.

Yellowstone and Grand Teton National Park: a nature photographer’s mecca.

©2013 Roman M. Kurywczak | Lens: Sigma 12-24mm | Focal length: 21mm | Aperture:  f/20 | Shutter speed: 1.0 sec | ISO 400 on tripod

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.

Mistakes, Mess-ups, and Missteps: It Happens to Everyone

One of our key missions here with the No Fear Photography blog postings is to teach photographers to take more creative control of their cameras in order to make stronger photos because taking the camera off full-auto-everything puts the power of shutter speeds, ISO and F-stops firmly in your hands. There’s many more variables, too, such as white balance, single/continuous Autofocus or manual focus, and so on to be tweaked and tuned. And the more controls you adjust, the more chance there is, that at some point in your photography, you are going to miss a shot due to operator error.

Nature Photography with the Sigma SD1 Merrill

© 2013 Alex Filatov | Camera: SD1 Merrill | 24-70mm F2.8 EX DG HSM | Shutter speed: 1/25 sec | Focal length: 24mm | Aperture: f16 | ISO: 100

When Sigma offered me the chance to shoot with the flagship SD1 Merrill DSLR, I jumped on the opportunity to extensively explore the abilities of the Foveon X3 censor at the heart of the camera. Knowing that my plans involved photographing the natural beauty of the mountainous American West allowed for the selection of several lenses from Sigma’s fine catalog most suited for that purpose – the 8-16mm F4.5-5.6 DC HSM wide angle, the 24-70mm F2.8 IF EX DG HSM mid range zoom and the 120-300mm F2.8 EX DG OS APO HSM telephoto.
