We loaded Rowan in the Suby and headed down to Pleasant Hill Lake, which was swelling higher and higher with spring rain. A lakeside campground had become partially inundated with water—a great place to let our pooch swim.
I dialed up my D800E to ISO 1600, which, in the late day sun, allowed me to shoot at f/8 at 1/2000 second. This gave me moderately strong depth-of-field and a shutter speed fast enough to stop Rowan running, splashing, and swimming as she retrieved sticks.
What’s bright, gives wonderful, round bokeh and is perfect for portraits, sports, street and product photography? Give up?
It’s Sigma’s 85mm f/1.4 EX DG HSM lens. This beauty fits on both full frame and cropped sensor cameras.
The ideal portrait focal length is said to be twice to two and a half times the normal focal length. So before diving into the 85 let’s take a look at focal length and what it means in regards to sensor size. First, here’s a definition or two.
What I’m hearing from readers is this: In your dog blog, don’t tell us how to take professional pet portraits; […]

Learning to use manual settings in your camera will provide you with the ability to create the beautiful exposures you desire. The exposure in your camera is determined by several different settings. Exposure refers to the lightness or darkness of the image. The settings are: 1) the aperture, the lens opening, which lets in light and controls the depth of field; 2) the shutter speed, the speed by which the lens lets in light, and 3) the ISO, which controls the camera’s sensitivity to light. The right combination of these three settings will give you a nearly perfect exposure and give you the effect you want for your image.
Prime lenses are designed for exceptional imaging at a single focal length. Unlike zoom lenses that easily span a given focal range and variable field of view with a twist of the zoom ring, the field of view and focal length remains constant. If you want to take in less of the surroundings with a given prime lens, you’ve got to physically move closer, and to take in more of the scene, you’ve got to back up. But of course, as you move, the angle of view remains the same all the while.
