I've been attempting to get used to using extension tubes with Canon 100mm, on a camera that does not have live view.
Of course, focusing has been the biggest challenge.
What can you recommend to get better at focusing?
Currently I use depth-of-field preview button while adjusting distance or focus.
Would I benefit from a macro rail? If so, which one? My tripod is a Manfrotto, but the Manfrotto macro rail doesn't seem to have good reviews.
Thank you for your tips.
