Tiny mite

I attached two 2x teleconverters to my MP-E-65 to achieve a total magnification ratio of 20:1. I was photographing grains of salt and after looking at the pictures on the camera's display, I noticed an extremely tiny mite looking thing.

ooh err thats very strange, it does look like its in the lens/TC, hope you get to the bottom of this problem, very interesting to see though

Yes there are mites that small and smaller(!). But I think it is on the camera sensor in these photos. Lens was stopped well down, right? That's how I check for sensor dust, eh? Looks vital and alive too -- who knows where it is now?

Yeah, I was also thinking it was on the sensor, as it looks very similar to sensor dust.

The photos were taken at f/2.8 but with the two 2x teleconverters, it becomes f/11.2.
