      Thanks for the link Gilles, have you tried the 4x version ?

      @ Brian : Thanks !

      @ Sonja : They were in my own hairs... I absolutely don't know where I got these insects. First thought that my kid gave it to me but he did not had any. I probably get it in the train... To prevent it from moving : freezing !

      @ Linden : No I did not tried the 4x version. But a (very kind!) colleague gave me a Leitz Photar objective that has probably a similar quality for magnifications around 5:1. According to my tests a good 28mm inverted on extention tubes has also an almost similar quality as the photar. When I see your results with the MPE-65 with wide aperture and extension tubes, I'm really wondering whether you would have a significant quality gain with these objectives. If ever you try it, please let me know !

      Ewww.... poor Gilles! Perhaps I should not have asked.
      I thought you got few specimen of interesting pests from some doctor or so to depict them, not a case of own parasites. :(

      This one is a wonderfull image, I like the adition of hair to the final image.
      So, are you using it with no extension? 30mm? I have used my BD plan 10x at 7x with good results on a full frame camera so I guess you can use this lens at 5x with no problem in an APS-C camera
      I still have to do the cricket picture, Is just that I do not have any at the moment

      Thanks to all.
      @ seta666 : (sorry for the late reply : holidays !) Yes without extension excepted the 30 mm of the adapter (F mount to T mount to RMS mount from a leitz Photar objective). This picture is rotated and cropped because I only had a microscope stand at the time I did this picture and it was difficult to obtain the exact composition I wanted. But the results are good also if you don't crop even in the corners at 5x.
      I found a dead wood cricket this week-end. I keep it for the winter !

      Thank´s for the info, I have used my BD plan 10/0.25 down to 7x with success on Full frame too.
      I have not been able to do the cricket shot as crickets I had were all female ( I am feeding a spider at home ) I will do the shots when I get a male

      That is the best image of a head louse I have ever seen. Nothing else comes even close!Fantastic work! David N. Gaines, Ph.D. State Public Health Entomologist Virginia Department of Health Richmond, VA.

      Amazing work this one..

      Thanks for your kind comments Tomas.
      If you have some recomendations about my pictures (ie lighting, post-processing...), they are welcome. Your stacking work is close to perfection (in my opinion). I could learn a lot from you...

      Staggeringly good demonstration of DFF.

      Thanks again for the CC license. I've used this photo here:

      My own pathetic first attempt is here:

      I'm using a real microscrope, so composing and lighting the subject is fairly easy, but my $40 Celestron camera doesn't do nearly as nice a job. It also has a tiny sensor so even with my lowest power objective I can't get the whole louse in the shot.
