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.

Why the New Lens Mount Conversion Service is Great for Photographers

Many times I’ve been asked on Facebook and elsewhere if it is possible for a photographer to keep their favorite Sigma lens and get a lens mount swap after making the decision to switch from one camera to the next, and now, finally, I can answer them with the answer they (and I) want to hear! As of September 2, 2013, owners of lenses in Sigma’s line of the Sigma Global Vision lenses: Art, Sports, and Contemporary, can now send their lenses in for a mount swap. This is a paid service, and lenses will be shipped to our Aizu, Japan factory for the mount conversion



Fan Photo of the Week: Richard Kuperberg’s Monastery

This week’s Fan Photo of the Week was made by Richard Kuperberg with the all-new 17-70mm F2.8-4 DC Macro OS HSM | C lens!

Camera: Canon | Lens: 17-70mm F2.8-4 DC Macro (OS)* HSM | C | Shutter: 1/320 – 1/250 – 1/80 sec | Aperture: f11 | ISO Setting: 100

He tells us:

Usually this Monastery (Chuang Yen Monastery) is very busy and hard to get a shot with out having people in the picture. Luckily I got off work early and headed there thinking I might have a shot at photographing the place with nobody around, my luck there was not a car in the parking lot. This image is HDR, and the new sigma lens ROCKS!
