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.
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.
Photographing in the field in contrasty harsh light is something every photographer has to deal with. This is a technique that I use for those difficult high contrast situations. For a more natural looking image you need to take control of the light to handle the light and dark tones in a high contrast image.
It is important to understand the problem with high contrast scenes. Exposing for the light tones will cause the darker tones to underexpose and exposing for the darks will result in blown out highlights.
The Sigma 50-500mm F4.5-6.3 APO DG OS HSM is one of my favorite lenses of all time. My copy has been there by my side shooting in rain, snow, freezing low temps, scorching high temps and more delivering the sharp images I need month after month.
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.
Judging by the number of questions I get from photographers concerning the working distances of macro lenses I think it is a good subject to talk about.
The working distance of a macro lens, not to be confused with minimum focus distance, is the distance between the front of your lens and the subject. This is different from the minimum focus distance which instead means the distance to the subject as measured from the focal plane mark on the camera body, not from the front of the lens. Working distance is a more important figure since it tells how much space you have between the front of your lens and your subject. Working distance generally increases with longer focal length lenses, shorter lenses usually have shorter working distances.
Brazil’s Pantanal is one of earth’s most biologically rich areas and truly spectacular photography destination. Last month I took a scouting trip to the Pantanal for wildlife with with special emphasis on the jaguar. It was my first trip here and I have to say the photographic opportunities in the Pantanal were even better than I expected. Jaguar was the main target of the trip and I would have been happy just to see a single one but as it turns out we had the chance to photograph them each day and every day I was there. This is one of the best locations if not the best location on earth to photograph jaguar.
