I have Canon Rebel T6. I'm looking for a "cheap" setup that will allow me to do Super Macro shots, 2x or higher, with a relatively large MFD, at least 1 ft. I have read that teleconvertor (TC) don't impact minimum focus distance. "TC do not affect optical characteristics of the lenses - they only magnify the center portion of the frame photographylife"; whereas, extension tube does shorten the MFD. I was looking at the Irix 150mm Macro (1:1 w/ MFD 1.1ft) len and a teleconvertor (2x or 3x). My end goal is to be able to be able to get 2x+ on an 1/4" objects that would be 12" to 36" away. I won't be able to get closer. I was thinking this will accomplish what I want in the cheapest manner. But wanted to see what other more experience photographers thought? is there a better setup that is cheap? better len? particular TC? some other hardware that could be useful?
