Yes you are right, the x24 is a challenge (the caterpillar was only about 2-3mm dia.) I was trying to make him enormous but lost depth of field.
I need much more practice.
I also need to find more bugs in my garden that are happy to pose.
In UK trying to use Sony DSC-V3 & Raynox CM-3500, a Nikon D70 and a 6x9 120 medium format pinhole camera
