Laowa 25mm: Hemitrichia at High Magnification and My Favourite Stereo

[Harold Gough]

I am calling this Hemitrichia as a working name but expect it to be correct.

We were about to start a survey at a local National Trust woodland nature reserve and took a look around the periphery of the car park. I looked on the undersides of two well-rotted old fence posts lying on the ground in a grassy area. This is the more photogenic one.

I took a sample home to shoot these images. The FOV is ca 3mm wide.

I love the delicacy of the transparent edge of the cup. The capitillium seems not to be going to expand, or at least not yet.

The (crosseye) stereo is one I could only have made successful with the 25mm lens.

Olympus EM-1 (manual mode), Laowa 25mm f2.8 2.5x-5x ultra-macro at f11, triple TTL flash hand-held.

Nice what you can find if you look hard. And well captured as ever.

Roughly how big are these? Do you mean the whole width of the image is just 3mm in real life?

Thank. Yes 3.5mm if uncropped. That's with the lens on "x5" which is x10 on m4/3. Magnifications refer to on a full frame sensor.

In the last half hour I just found a lovely group by accident. I was using a small block of the rotten wood to prop up a larger one to photograph a colony. Having finished, as I picked it up to take it outside, I spotted a tiny, fuzzy, yellowish object in one spot and got some lovely images of fruit bodies looking very much like the same species as illustrated here.
