Does anyone have experience with them?
I am already buying the extension tubes, are they worth to buy to use together with the tubes? i regain some working distance right? how about increased magnification?
ET+100mm macro gets me 2:1, what would i get with TC + ET + 100mm macro?
I can't figure why the 1.5x
is cheaper then the 1.4x
, does anyone know why (i mean the diferences between them)?
thanks,
