Getting greater than 1:1 macro lens magnification

[glsammy]

Using a Sigma 150mm macro lens, plus 3 extension tubes can produce shots such as this:



Now that insect was very obliging. I was almost touching it with the lens. Actually the 150mm is not the best lens to use with extension tubes as the higher the magnification of the basic lens the less extra magnification you get when using tubes. A 90mm lens would give even more magnification that this shot.

I think it's more like - the longer the focal length the less extra magnification you get when using tubes.

Lighting provided by flash should also get such detail, ensuring there is no motion-blur.

You can make out the compound eyes of inverts with my £40 microscope.

I used a 'ring flash' for the leaf cutter bee and sand wasp, above.
