this is old news to many,
but will be news to newbies,
With ANY CEVIL camera that has live view (are there any which don't have it?) including but not limited to M43 and NEX cameras, and all of their competitors ...
Using ANY lens, native lens mount or adapted lens via adapters...
To FOCUS CLOSER, MUCH CLOSER
Just add CLOSE UP LENSES to your lens and then focus by live view!
Close up lenses look like regular screw in filters and are usually sold in an inexpensive set of 3 by the filter size.
