These guys are currently the dominant species in my overwintering pond water (in the garage). Almost too dense to photograph with transmitted light; also very active.
Anterior end to the right; beaded nucleus; striated surface; short cilia all over the surface.
Olympus 10x SPlan achro.+ 1.25x intermediate lens + 2.5x relay lens; DIC.
The scale is a micrometer slide photographed at same scope setting.

It's a pity that DIC prisms are hard to find, and once found are often prohibitively expensive. Under 'regular' transmitted light these beasts are featureless, you just seel a body with lots of small circles (probably food storage particles). I just love looking at small 'animacules' under DIC.
DIC also works well with plant cells. A recent article HERE
describes how to see onion cells' nuclei using a stain. With DIC you can look at live cells and see the nuclei and the cytoplasm streaming within the cell (the lines crossing the cell):

I can look at these images all day. They contain so much information that is easy to understand once you see it. I just wish my old scope could do it. LOL
Thanks Charles. I'm still not getting the clarity and quality you are getting
