I should have included the size of the face of this toy to give viewers an estimation of the magnification being accomplished. It is about 1/2 inch high and 1/2 in wide.

For the shot with the standard lens inversely mounted, the magnification is about 4 times. The calculation being: the length of the bellow divided by the focal length of the lens. In which case, the bellow lenght is 200mm and the focal length is 50mm, so the magnification is +4.

The aperture for that shot is about f32. I based the calculation on the magnification used, in which case it is +4. For 1 degree increase in magnification, the aperture becomes 1 stop smaller. In my case, the aperture is 4 stops smaller. The story does not end here. One more stop has to be added to work out the resultant aperture. So, last night, I used an f5.6 on my standard lens and the aperture after the bellow extension has become f32.

Thanks for viewing and giving comments.
It took my eyes to focus well as I closed in. Vibration is killing me, too. It is fun, anyway.
