Of course, these functions can be used either separately or combined. A lever located at the right side of each TS-E lens allows it to be turned vertically when mounted on an EOS camera. It is quite difficult to turn any of the TS-E lenses vertically when they are not mounted to an EOS camera. In this issue, the lens being reviewed is the TS-E 90mm f/2.8 version. Weighing at only 565 grams, it is the lightest of the trio and uses a 58mm filter thread as opposed to the 72mm versions employed by the other two versions. The closest focusing distance of this lens is 0.5m/1.6 ft, close enough for a postcard-size subject matter. The internal construction consists of 6 elements in a 5-group arrangement. It is also the world's first telephoto lens employing the Tilt & Shift features. Effective use of the tilt mechanism enables the creation of precisely-focused, high quality images even when dealing with shallow depth-of-field during close-up shooting. These photos of a TAMIYA 1/12-scale model of five-time World 500cc Champion Mick Doohan's all-conquering Honda NSR500 GP bike were shot with the lens at its maximum f/2.8 aperture opening. Model bike without Tilt feature 24mm's angle-of-view As can be seen, depth-of-field was very shallow when no tilting was employed. In the second photo, the tilt mechanism was utilized to give adequate depth-of-field to the model bike even at the maximum aperture opening. The tilting mechanism allowed the lens barrel to be parallel to the model bike's side angle even though the film plane (camera) was not. Below are more examples of how the TS-E 90mm f/2.8 Tilt & Shift lens was used to increase the depth-of-field in both product and still-life photography. First, the canned lychees and the Coke were shot (f/2.8) without the Tilt mechanism being utilized, resulting in the shallow depth-of-field. With the lens barrel tilted towards the left, both the canned lychees and Coke were brought to focus, also at f/2.8. Canned lychees and Coke With Tilt feature utilized     Snappers without Tilt With Tilt feature utilized Next, the photos of the snappers were also shot with the same method with the TS-E 90mm lens. Both were also shot at the lens' f/2.8 opening. The first photo, without the tilt mechanism being employed, did not allow adequate depth-of-field to cover the whole scene. By tilting the lens barrel towards the left, the snappers lying on the right side of the photo could now be brought into focus with the extended depth-of-field made possible. << Back to Main . 1 . 2 . 3 .
