KEH Specifications

The Pentax Helicoid Extension Tube K works like a close-up ring, and can be elongated from 26.5 mm to 46.5 mm since it has a 20 mm long helicoidal thread exactly for this purpose. The length of the tube is approximately to a No. 3 or Nos. 2 + 3 of the Auto Extension Tube Set K. However, it cannot be used to achieve the lower magnification ratio you get with the No. 1 rings of the Auto or regular Extension Tube Sets. However, if it is used in combination with the lens's focus ring, the wide range of magnification ratio becomes possible. 

Compatible cameras: Pentax K (AF,) KA, and K-mount cameras

Compatible lenses: SMC Pentax, SMC Pentax-M, SMC Pentax-A, and SMC Pentax-F

Elongated length: 26.5 mm (minimum) - 46.5mm (maximum)
