The Tamron 70-200mm f/2.8 Di Macro Lens delivers sharp images from a great focal length range and a wide/fast aperture. It is a light and economical package. The autofocus system is the clear downside to this lens.

Overall, and especially for the price, I'm very pleased with the image quality of the Tamron 70-200mm f/2.8 Di Macro Lens. On the wide end (70mm), this lens is sharp wide open (f/2.8) across the entire 35mm frame. Stopping down only makes a small improvement in sharpness - reduced vignetting is the primary difference seen. By 100mm, the center is still sharp wide open, but corner softness is setting in due to a slightly curved focus plane. Stopping down to f/5.6 results in excellent image quality across the frame.

The weak spot for this lens is 135mm - especially in my first purchased-retail-new copy of the Tamron 70-200mm f/2.8 Di Macro Lens which exhibited a very soft right side. This was due mostly to a curved focus plane but the left side was far sharper than the right side (examples showing the right side of this lens are shown in the ISO 12233 test results for lens sample #2). Here is a closer look at the problem that was most apparent at 135mm f/2.8.

Flash units can come in many sizes and shapes for digital photography. Those cameras on the lower end of the scale come with low energy built in flash units. However, some gear such as the high end digital SLR cameras can accommodate external flash units advanced in their abilities to provide excellent lighting in complicated situations. Know the basic facts about the difference between built in and external flash units.

Many advances have been made with flash units since the early days of photography. In photography's infancy, flash units were using powder that was lit by electrical current and then "blown up" to generate the light energy. This method was most certainly a risk. It also proved a challenge as the flash units were not automatically in time with the camera's shutter so the photographer had to coordinate the flash to go off at the exact time the photo was shot.

Today flash units have eliminated this challenge. An electronic flash tube ensures flash timing is synchronized to the camera. The photographer now gets to concentrate on other aspects of the photo. New digital cameras can even determine on their own if the flash is even needed, set its intensity and other parameters and fire the flash at the precise time the shutter is opened. All of this is automatically done in the background. Should the user want to make their own adjustments, digital cameras also allow the user to manually control the flash, set its intensity and...
