Last image with the Olympus for now and I'll be posting some images taken with the Pentax 135 f3.5 lens as from tomorrow so you can see the difference in lens signatures. The reason for this image is to emphasize the need for stopping the lens down on these longer lenses, even on full frame cameras. This image (which was taken at f11) has some out of focus parts to it. It just shows I needed to stop down to about f16 for everything to be in focus. The closer you are to the subject, the more you need to stop the lens down for maximum depth of field within the image.
