Hi Folks.
I have been doing some macro shots and I wondered if anyone knows a simple way to know what magnification a lens and tube combo will give, for example I have a (cheap) tube set, 13mm 21mm and 31mm tubes, if I add each to a 24-105mm lens what magnification will I see.
I don’t really want the answer so much as a formula or a recommendation for an app to calculate this if anyone knows of one?
Cheers, Graham.
