I purchased this Schneider lens last December and only now has there been a subject of interest. After discovering my only source of these tiny flies I tried maximising the magnification on my Kiron 105mm with a +5 Marumi achromat on the front x1.5 TC behind it. The results were discouraging, possibly due to reflections and flare.
Today I tried with the Claron on 200mm of extension. The location of the flies, on the inside of a dark grey compost bin lid made the task difficult. I needed to position the flash off the camera, inside the upturned lid but without shading the flies from the sun, which I needed for framing and focus.
The field of view was 5mm wide and the working distance about 60mm. Mites in two of the images confirm the scale.
I varied the aperture and the shots were probably all at f11 but f16 is a possibility. I really wanted to try f22 but the flash was too weak. Noise was bad enough at ISO 800 without going to higher values. The camera was hand-held.
The first image is where I initially put an additional 10mm of extension on. Interesting possibilities for another day!
Some purple hue arose from severe noise reduction. The third image is about the correct colour.
