Canon Demi HS 30 mm/17 lens transplantation, 6 elements and 4 groups

Probably the lightest lens is prepared by DIY arrangement utilizing Canon Demi HS 30 mm/17 lens with interplantation, weighs only 86 gr.. Half size imaging circle obliges to crop down to SPS-C format, but it's permissive for my usual use as a standard focal length lens. Iris control is available by adjusting a lever rotating and extraordinary 20 cm close-up capability is an indispensable gospel at all even with an original helicoid parts diversion. Cute and adorable appearance of this modified lens has an enough potential to surprise and frighten even a SONY engineer. 6 elements and 4 groups lens design construction has enough advanced concept even on Digital Imaging Sensor, no argument is acceptable to show it's resolution power and sharpness with delicacy. Small & Cute figure do not mean less capability even on a recent designed sophisticated Digital equipment.
