Extension rings vs teleconverter?
This may already have been discussed, if so, I beg everyone's indulgence.
I wonder if someone could, please, compare the advantages and disadvantages of extension rings vs teleconverters with regard to close focusing?
For example, if using a 50mm or 24mm lens and wishing to engage in close focus photography (say, up to around 1:1), is there any advantage in using, say, a 25mm extension ring over a 2x teleconverter? Ditto regarding a 50mm Macro lens?
What are their respective advantages/disadvantages?:confused:
