Exercise 2.1 – Effect of focal length 1

These images were all captured with an Olympus E-30 camera; various lenses. All are JPEGs, reduced to 1500 pixels on the longest side and used uncropped. Metering is aperture-priority automatic, set to f/8. The automation gave shutter speeds between 1/30 and 1/80 seconds, the majority being either 1/50 or 1/60 seconds, no adjustments in post-processing. All images are taken  from the same viewpoint, with the camera mounted on a tripod.

The E-30 is a Four-Thirds format camera, with a crop factor of 2.0

With a portrait-format image, like these, I find the 25mm (50mm equivalent) is closest to my normal perception. With landscape format images I prefer a slightly longer focal length of 35-40mm (70-80mm equivalent). In earlier times, using 35mm film cameras and prime lenses, my favourite was the 85mm which I consider to be a ‘long standard’ rather than a ‘short telephoto’
