4.【Flexibility】Tube Lengths: (1) 12mm.(2) 20mm.(3)36mm, use alone or combinations. Note! The focal length of lens should be greater than the length of the tube,to achieve your desired focusing result ..
5.【Auto Focus & Exposure compensation】Note: it needs appropriate ocusing distance(1-3cm) space to Auto Focus function. When use 3 tubes together, there is a little difficult to auto focus. Suggest use manual focus or Increase the lens focal lengths to avoid blurry. & Use all shooting modes of the camera, exposure compensation is required. recommend use the manual mode to change the shutter speed directly to control the exposure level..
