With a twist of the wide zooming ring, you can change from the lens' 28mm to its 200mm quickly. To give an idea of how the angle-of-view changed within the range of focal lengths available with the EF 28-200mm f/3.5-5.6 USM zoom lens, these photos below were shot at Sunway Lagoon's outdoor theme park and its surrounding areas. At 28mm At 35mm     At 50mm At 70mm     At 135mm At 200mm As mentioned in the previous page, close-up photography is possible with the EF 28-200mm USM. Plus, both the Extension Tubes EF 12 and EF 25 can be used on this lens as well as its DC Motor counterpart. To get really up close to small objects, you have to set the zoom lens to its 200mm focal length, switch to manual focus (AF is possible but manual eliminates lens tendency of hunting) and set it to its closest focusing distance and move in towards the subject until focus is achieved. If the object is smaller than a 4x6 inch print, there will be plenty of empty space surrounding it. And this is where the Extension Tube comes in to solve the problem. With the EF 25 Tube attached, the EF 28-200 zoom lens can now focus much closer than before, as shown in these photos below of the pens and pencils. See the difference in the before and after shots. At the closest focusing distance (200mm) With EF 25 Tube attached (200mm) The slightly warmer cast apparent in the shot without the EF 25 tube attached was caused by the color of the ceiling where the flash light bounced off. In the photo shot with the EF 25 Tube attached, the built-in wide panel of the Speedlite 540EZ was used to reflect some of the bounced light to the subject as the lens was too close to the subject matters and would block out the lighting if it were fired the same way as with the first image. << Back to Main . 1 . 2 . 3 .
