All images taken with Olympus 12-40mm zoom at f22 to f16 and shutter speeds of between 1/4’ and 1/30’

Using these shorter focal lengths affects the perspective of objects which are close to the camera; they appear much larger compared to the background content, sometimes dramatically so.  The 12mm end of this lens is 24mm equivalent due to the cameras small sensor and would probably be considered a medium wide-angle.

With the lens stopped right down the amount of light being transmitted is greatly reduced, requiring much longer exposure times.  Had there been any movement in these frames there would probably have been noticeable motion blur.  As it is, holding the camera steady is a problem as 1/30’ and lower is too slow for handholding.  The inbuilt image stabilisation helps but resting the camera on a steady surface certainly improves matters.
