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.
Over the last few months I have been testing the newest version of the Sigma’s 120-300 f/2.8. I have nothing but good experiences with the older version of this lens so I have been looking forward to working with this lens over the winter and spring at home in Southern California. So far my experiences have changed my view of this lens, the newest version of the 120-300 f/2.8. The previous version was good. I found that this latest version has quick and accurate autofocus; the image quality is superb and the focal range excellent for nature photography.
The Sigma 105mm F2.8 Macro EX DG OS HSM lens has become one of my favorite lenses for macro photography in the field. So what makes me reach for this lens when Sigma offers five macro lenses when I own all of them? The answer is balance- the 105mm lens is really good at everything and one of the best in terms image quality. This lens can give you the sharpest results possible with an excellent balance of size, weight, working distance at a very high value per dollar price.
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 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.
One of the most important rules for macro flash photography is balance. For natural looking macro images you have to balance the ambient light and flash output. When the flash and ambient light are balanced the use of flash will not even be apparent to the viewer.
The problem is that with flash output overpowering the natural light in background it will underexpose and go dark, in some cases like the image below, it can underexpose to the point that is appears black.
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.
