FotodioX Pro Automatic Macro Extension Tube Kit for Canon EF-M

Shortening the minimum focusing distance of Canon EF-M-mount lenses, this Pro Automatic Macro Extension Tube Kit from Fotodiox enables you to achieve a greater maximum magnification for close-up shooting. Extension tubes enable macro performance for lenses not otherwise able to focus that close, and are also suited for close-up portraiture. This kit contains both 10mm and 16mm tubes, which can be used independently or in combination for various altered reproduction ratios. Additionally, integrated contacts maintain full autofocus functionality and also automatically compensate for any exposure adjustments needed when using TTL metering or auto exposure settings.
