Hasselblad Carl Zeiss C Distagon 40mm f4 Lens w/ Case
This is the cool vintage wide for all of the 500 series cameras. It seems like it's about as wide as you can get on a Hasselblad without using the Super Wide Camera.
This lens is in excellent condition and works perfectly. The glass is clean and scratch-free, the focus is smooth and the shutter is strong and accurate. It comes with the original branded caps and case.
This is a nice one.
