This is used by attaching between camera body and lens of the 35mm single-lens reflex camera, it comes as a set of 3 tubes of different lengths which

singly or in combination makes it useable in 7 different lengths,it couples perfectly with the camera's automatic diaphragm,with cameras of TTL,AE

(Through-the lens,Automatic,Exposure)type it gives perfect coupling expect when combined with electronic flash AE unit.the imagic magnification ratio

becomes smaller as the focal length of master lens becomes longer and the larger as the focal length becomes shorter also,the distance to the subject

becomes further away as the focal length of master lens becomes longer and closer when it becomes shorter.In close-up shooting, as the subject's depth

of field becomes shallow,never forget to stop down the lens.take care that when image magnification ratio increases camera shake is also liable to

increase.(the use of tripod and cable release is advisable.)
