Spring is here, life is coming back

Macro Nature

This week temperature has risen to almost comfortable levels – 10-15 degrees Celsius. This means that insects and flowers are emerging i larger numbers, so I grabbed the camera with the Sigma 105 f/2.8 Macro lens and spent an hour on the ground in the garden.

Even though photos here are taken on f/10 to provide a large depth of field (DoF) it’s not that large. I get a very small DoF because I’m using 105 mm focal length and because my focus distance is 31-45 cm, as you can see actually only 3-5 mm of the image depth will be rendered sharp in the final photo.

Dof is only 3.8 mm at 38 cm focus distance but increases to 5.7 mm when using 45 cm distance

Luckily it’s only small items i have been photographing today, so most can be included in the DoF, but even a 4-5 mm long spider easily fall partly out of focus.
