Posted June 4, 2008. Before you spend money on extension tubes for a (short) 50mm lens, you need to consider both minimum and maximum focus distant. With a 12.5mm tube (the shortest you can buy for EOS mount), your maxmum focus distant is ~34 CM. Since an EF50 has a minimum focus distant of 45 CM. This mean, any time the subject is between 34 The function of the camera and lens is unchanged, and you can combine extension tubes for greater magnification. Canon offers two extension tubes, the EF 12 II and the EF 25 II. Magnification differs by lens, but with the EF12 II and standard zoom lenses, it is approximately 0.3 to 0.5. With the EF 25 II, magnification is 0.7. 1. As I recall, it's the 25 mm tube that I use with the 55-250 lens. It works well for closer focusing. The lens manual has the documentation that one needs to decide which tube to use. ThrillaMozilla's gear list: Canon EOS Rebel SL1 Canon EOS M6 II Canon EF 400mm f/5.6L USM.
