Olympus M.Zuiko Digital ED 40-150mm F2.8 Pro Lasiommata megera Wall Brown

Even though the Olympus M.Zuiko Digital ED 40-150mm F2.8 Pro lens is not a dedicated macro lens, you can still take very detailed photos like this butterfly thanks to its 70 cm focus distance. The Olympus Micro Four Thirds format has a crop factor of 2, meaning I'm effectively shooting with a 300 mm full-frame equivalent.
The lens is of a very high quality; the photos are sharp, and the 2.8 aperture provides a level of brightness that I'm not used to.

It was sitting on a pile of sand, overgrown with weeds in an abandoned sandpit. Unfortunately, a blade of grass or a root hanging in the air cast a shadow.
I remember that the focusing point was fixed on the ‘eye’ on the wing, but that's understandable, there is contrast. However, it caused the head to not be super sharp even though the aperture of 8 is not small at all.
