Harvestman Eyes Through Photar 2.5mm
 
There is not much arthropod fauna around as we approach the start of spring. Most that is to be found, in my garden, is on, or mostly under, rotting wood on the ground.

This individual was on the cut end of a log, with a step in the cut just to its right (my left) which limited the shooting and lighting angles. It was about finger nail size, its legs extended and somewhat flattened. At such a magnification, the DOF is tiny, making shooting at two angles for stereo challenging. However, I got more "keepers" that expected.

I recently posted some old images which were probably of the same species. Those were with the 50mm Photar.

The stereos are crosseye.

Olympus EM-1 (manual mode), Leitz Wetzlar Photar 25mm f2.5 macro at f16, twin TTL flash, hand-held with support.

For this series of Photar 25mm images the lens was on almost 100mm extension. The images are uncropped. FOV ca 3.7mm wide.

I have removed some traces of sensor dust which I missed:

I saw another of the same species today. This time, I could get a lower angle. I shot at f16 on the extension for x2.5, FOV ca 7mm. Twin flash.

Here is a single frame and a crosseye stereo.
