Sigma’s 105mm F2.8 Macro OS

© 2014 Robert O'Toole | Sigma 105mm F2.8 EX DG OS HSM Macro, Nikon D800E, manual mode, 1/200th s at f/8, ISO 640, Single SB-R200 wireless flash at 1:8 power manual mode, handheld.

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.

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.

Macro Flash Photography: Create Natural Looking Macro Images

©2013 Robert O'Toole | Exposure mode: Manual mode | Shutter speed: 1/200th sec | Aperture: f8 | ISO 200 |  flash @ 1/40 output level | Lens: Sigma 105mm f/2.8 OS macro lens

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.

Morning at the Reflection Lakes, Mount Rainier National Park

Stormy Monday

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.

Macro Photography: How Sensor Format Affects Image Depth of Field

© 2013 Robert OToole Photography | Lens: Sigma Macro 150mm F2.8 EX DG OS HSM |  Camera: NIKON D800E | ISO: 100 | Aperture: f8 | Shutter speed: 1/250 sec | single SB-R200 flash. This flower was framed in the viewfinder with a full frame sensor format body in FX (full frame) mode.

One of the biggest challenges with macro photography is working with a limited depth of field or DOF. When I am shooting macro I am always trying to make sure the subject and elements in the frame appear sharp by adjusting the aperture and making sure the important elements in image fall on the plane of focus by adjusting my angle of view. But there is another important element that has a huge effect on DOF that most people don’t even know about, how a different sensor format can and will effect the depth of field in your image. Moving to a smaller sensor format at the same apparent magnification will give you lots more DOF to work with in your macro images.

Making the Best of Opportunities in Nature Photography

As photographers, we often strive for that “perfect” image. Those who are most proficient in their art, in one way or another, pre-visualize the final photograph and strive to exercise the most possible control over all the variables involved in achieving the desired end result. The reality is that outside of the studio and particularly true in nature photography, all bets are off. The extensive planning and meticulous research performed prior to photographing a never before visited location may prove useful or lead to a near-fruitless and frustrating trip. The landscape artist cannot control light and precipitation and is always at the mercy of Mother Nature. Sometimes you have to come to terms with the fact that the iconic shot you saw in someone else’s portfolio will probably not be in yours. This is where you have the chance to prove your worth as a photographer by using your imagination and compositional skills to improvise and make the most out of the presented opportunities.
