While trying out this lens I wanted to try out the results
of shooting at minimum focus distance wide open both at the wide (18mm) and
long (200mm) ends to see what the results were like. Chiefly I was interested in sharpness and how
much the foreground and background would be blurred out. Both photos aren’t quite at MFD, though about
60-70cm away from the subject, which is close enough to see the characteristics
I wanted to measure.
At 18mm f3.5
Sure putting potted daisies on a tractor is a little odd,
but it does help to distinguish the subject from the background. The subject is perfectly in focus and very
sharp. The background, which is about
1-2m behind the flowers, is very visible, and only on closer inspection can you
see that it isn’t sharp.
At 200mm f5.6
Significant narrowing of the depth of field can be shown at
200mm, but it certainly isn’t like looking through a pro tele-zoom such as an
80-200mm f2.8. Still it can effectively
blur out the background and separate out the subject.
