Sharpness Cont... 2

Sharpness at 25mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The lens was attached to an Olympus E-3 body, which in turn was mounted on a sturdy tripod. The two-second self-timer option was used. Slight colour changes are due to slight changes in natural light during the session. The 100% crops represent about 1/250th of the total frame area. Sharpening was at its default value of zero.
