TAMRON | [Nishihira's method] How to Maximize the Power of the Tamron 28-300mm Lens with Built-in Vibration Compensation (3) These are applications and proper method for using VC

For full use of the VC mechanism, test the slowest shutter speed in advance.

High-power 28-300mm zoom lenses are convenient, but pose an inherent problem: camera- or hand-shake in close-up photography. Generally, the slowest shutter speed is 1/focal length second. This means that the slowest speed at the 28mm wide-angle end (45mm-equivalent in the 35mm format) is 1/50 second, and it is 1/500 second at the 300mm tele-end (480mm equivalent) when the lens is on Canon EOS DSLRs with an APS-C-sized image sensor.
A shutter-speed difference of 3 or more steps causes blurry pictures. However, with the Tamron 28-300mm VC, which exhibits its vibration compensation performance equal to four steps in shutter speed, you can take sharp pictures without blur from hand-shake, at 1/30 second and 300mm settings with your camera handheld. The slowest shutter-speed limits to capturing sharp images in hand-held photography differ considerably depending upon photographic conditions and from individual to individual. Therefore, for full use of the VC function, determine the slowest shutter speed with your skill, by testing in advance.
To shoot trial pictures, choose a still subject and capture its image repeatedly, at infinity and at a working distance of about 1 meter, with the VC mechanism ON and OFF, with and without a tripod, and at different focal lengths and shutter speeds. By checking the resulting images, you will be able to ascertain the slowest shutter-speed limit you can use in hand-held photography.

Taking picture by using blur from the main subject's movements

With conventional lenses, if you take creative pictures by using blur from the main subject's movements, the images will probably be blurry because of hand-shake. However, with the Tamron 28-300mm VC, you can create images like this by capturing the main subject's movements.

These two pictures were taken under the same conditions. The picture at the right is a failed image due to blur caused by the main subject's motion. To prevent blur caused by the main subject's motion, you have to wait for the main subject to stand still or use a faster shutter speed. The VC mechanism can minimize hand-shake, but it won't prevent blur caused by the main subject moving. The picture shows my unsuccessful attempt to take a picture exploiting blur caused by the subject's motion.

To prevent hand-shake, you have to take countermeasures against the blur caused by the main subject's movements. You can minimize hand-shake or camera-shake with the VC compensation function, but you can't prevent the main subject from moving. In sports photography or with pictures of animals or children, subjects are in constant motion. Even when you take pictures of scenery, trees or flowering grasses will move if blown by the wind.
The most effective way to prevent blur from the main subject's movements is to use shutter speeds that obscure your main subject's motion. If you use slower shutter speeds expecting the VC to function, your images may be blurry if your main subject moves. The extent of blur differs depending upon motion of the subject and magnification ratios, so go with the slowest possible shutter speeds on a case-by-case basis. If the resulting images are not sharp, use a 1-step larger aperture and a correspondingly faster shutter speed. Alternatively, use a 1-step faster ISO speed.
If you make full use of the VC function, you will be able to prevent hand-shake and take creative pictures by using depth of field, as well as motion from the main subject. By adding the Tamron 28-300mm VC to your lens system, you will enhance your skill, creativity, and results.

Sample Pictures Show the Power of the VC Mechanism

Hand-held shooting without the flash and the tripods

Pictures that were difficult to capture with conventional equipment can be created by making full use of the VC function and faster ISO speeds.
Conventionally, photographers had to use flash to take pictures of this kind of a scene. However, with the VC function and a faster ISO speed, you can take pictures like this without flash by hand-held photography.

This shot was taken with the Tamron 28-300mm VC at its tele-end. Slow shutter speeds (1/40 - 1/25) were used to show the motion of the rotor. With conventional equipment at a slow shutter speed setting, the images would have been blurry from hand-shake. However, with the Tamron 28-300mm VC, you can show the motion of the rotor while minimizing blur from hand-shake.

You can take close-up shots of subjects like these, where you cannot get closer. This is the greatest attraction of high-power zoom lenses. For example, if you use the Tamron 28-300mm VC with a Canon EOS 40D, you can use the lens as a high-power zoom lens to provide a range of angles of view, equivalent to 45-480mm. A tripod used to be essential with ultra-telephoto lenses to prevent camera-shake, but with the Tamron 28-300mm VC, you can take pictures similar to these by hand-held photography.
