Can one of the macro experts please explain (for a total newb) what is meant by "reverting" the lens (or is it "reversing")??
Hello Andrew, It's actually "REVERSING" the lens, and there are special adapter rings you can buy that will mount onto the camera body, and the other side of the adpter will have a set of threads (Threads are available in various different sizes to fit different size lens filter threads.) The idea is to mount a lens (Usually a 50mm) backwards on the camera body, and some will mount the backwards lens onto the end of another lens that is mounted right way around.
A reversed lens will focus extremely close, but all settings will need to be handled manually, including focus.
There are several different options for shooting true macro.
Extension rings enable a standard lens to focus much closer than it normally would.
You could pick a macro lens that is designed to focus extremely close from the factory.
Reversing the lens is of course one of the options.
If you want to get into extreme macro of static objects, you might want to have a look at this thread, https://photography-on-the.net …d.php?p=683965#post683965
I hope this has answered some of your questions.
