Less CA, almost 3X the working distance over my Nikon 10X. I'm experimenting with different lighting for this objective. Especially crisp with the low CA when used on the APO Voigtlander 125mm tube.

Finally! The adapter for my Mitty 10X arrived. 10X on Micro Nikkor 200mm f/4

Here is a quick side by side of the 105 and the 125.
It was very obvious in the individual shots that the Voigtlander was sharp, had less flare and less CA, easily seen in the color cast to out of focus areas even in the final stacked image. These are with almost identical setups, camera only moved in and out a bit for the direct length of lens, identical lighting. Now, I suppose that the slightly higher effective aperture of the 125mm mitty combo over the 105mm means those images were slightly darker, the EA going from 9 and change to 11 and change. I don't believe that there is also a greater depth of field or improvement in sharpness since I've been told that step size is based only on NA and not on magnification. Still, I think the 125 is quite a bit better with the mitty, where it's harder to tell them apart with the Nikon 10X.

Nice beetle pictures and an interesting lens comparission.
