Even 1000 ISO on a 7D Mark II, which I'd consider a LOW ISO for shooting sports, may be too high for shooting a wildlife photo with a mostly stationary subject. Do this at various focal lengths and you're likely to see a big difference. In situations where you already have enough natural separation between the animal and the background, it's nice to be able to stop down the aperture just slightly if your shutter speed is high enough. This effect is similar to moving closer to the object, but is not the same, since perspective is a function solely of viewing location. Two images taken from the same location, one with a wide angle lens and the other with a long-focus lens, will show identical perspective, in that near and far objects appear the same relative size to each other. When I'm shooting with a 500mm lens, I don't feel that I have to shoot at 1/500 all the time. The perspective of the so-called normal lens, 50 mm focal length for 35 mm film format, is conventionally regarded as a "correct" perspective, though a longer lens is usually preferred for a more pleasing perspective for portraits. Many long lenses offer more than one image stabilization mode, and selecting the proper stabilization mode can make a significant difference in the sharpness of the photo. When shooting sports, the monopod is NOT used to stabilize the image. If I'm taking a picture of a bighorn sheep that is mostly stationary, I'd love to be able to drop the ISO as low as possible as long as the shutter speed remains reasonable. They actually work very well when balanced on a car door or window! Let me know in the comments what I've missed. You'll only see monopods. This means it’s a 50mm (regular angle) fast lens with an aperture opening of 1.8 (wide). Thank you so much, Mr. Harmer. Look at this shot of a coyote that I shot in Yellowstone today. If you can get closer to the animal or the action by stepping closer rather than zooming in, you'll sometimes see a nice sharpness advantage. This is also partially to support the weight of the lens, but also because wildlife shots are not always action shots, and wildlife are often photographed in dim conditions. Now you understand why focus is slow on long lenses. Some people say that the grain in a high ISO shot can make it feel sharper because of the fine texture it puts on the photo. If you are buying lenses from Ebay the seller may post their lens with the following classification. However, use caution with high ISOs when shooting wildlife if the animals are not moving around too much. When I zoom in on the fur of the coyote, you can see exactly why the photo doesn't feel sharp. I can’t wait to try some of these techniques. This is true up until about 1/800 shutter speed. The conventional wisdom when selecting a shutter speed is to use the 1/focal length rule, which means that you choose a shutter speed denominator equal to your focal length. One thing that is often not discussed in photography is the effect of ISO on sharpness. Here is a rundown of some of the long lens techniques I've learned. Your fox vs duck shots show how much considering the so-shallow DOF matters, what is or isn’t in the focal plane. If it takes that much force for you to twist, think of how hard the lens's focus motor has to push to get it to move. Long-focus lenses are best known for making distant objects appear magnified. The most commonly photographed aperture with any long lens is wide open. A long-focus lens is one of three basic photographic lens types classified by relative focal length, the other two being a normal lens and a wide-angle lens. [5] Its a little more rigid but you don’t have to worry about beans/stuffing migrating away from the edge of the glass. Aside from the increased depth of field, you'll also find that virtually all lenses are sharper when stopped down from the max aperture. It is used to make distant objects appear magnified with magnification increasing as longer focal length lenses are used. Generally, long lenses offer two image stabilization modes. … PDF: Short Focal Length, Wide-Angle Lenses . Resting the lens further back (toward the camera) on the car can still leave a significant amount of shake in the lens. Mode 2 is most commonly used by bird photographers, but could be used in any wildlife situation. It is used to make distant objects appear magnified with magnification increasing as longer focal length lenses are used. There are times like when its windy that setting the bean bag on your tripod and then the lens on top of that reduces wind shake and vibrations. [6] Besides being used in an astronomical role in astrophotography, telescopes are adapted as long-focus lenses in nature photography, surveillance, machine vision and long-focus microscopy.[7]. Combine that fact with the common scenario of renting a long lens for a special wildlife photography or sports photography trip, and you're likely to make a lot of mistakes.

Joe. Will definitely share the info with my customers! From the invention of photography in the 19th century, images have been captured using standard optical telescopes including telescope objectives adapted as early portrait lenses. Raising the ISO seems like a panacea for better action shots with a long lens.

I think the 1/focal length rule makes good sense up to a point. Effect of different focal lengths on photographs taken from the same place: The above photos were taken using a 35 mm camera, using lenses of the given focal lengths. Shooting with a long lens requires a very different set of skills and techniques than shooting at normal focal lengths. But don't feel like you always have to use a tripod when shooting wildlife.
