Taken today on a quick visit to Clumber Park in search of fungi. There were lots of flat topped fly agarics but not many of these closed ones. This time I not only took the closer shots but some more environmental ones like this.
The 100mm has a good rounded aperture which gives great out of focus background highlights.
Pentax K20d and Pentax 100mm macro - 1/30sec at f/2.8 and ISO 200
