For sale here is a mint Bronica EC-TL II 6x6 camera with Nikkor 75mm F2.8, Zenzanon 40mm F4, and Zenzanon 50mm F2.8 lenses.

EC-TL II is the last model of Bronica's focal-plane 6x6 cameras, which included D, S, S2 S2a, EC, EC-TL, and finally EC-TL II. EC-TL and EC-TL II have aperture-priority automatic exposure mode. This is unique among 6x6 single-lens reflex cameras. Others need an AE finder to have automatic exposure functions. The camera is in mint condition and works perfectly. It has its Nikkor P.C. 75mm F2.8 lens.

The star of the set is the Zenzanon 40mm MC F4 pancake lens. It weighs only 330g and has a filter thread of 67mm. The last two pictures show the 40mm on the camera. Nikon originally provided a Nikkor 40mm F4 but it is much larger with a 90mm filter ring. A user has used both and said the Zenzanon 40mm is "much sharper" than the Nikkor 40mm.

This lens is Extremely Rare. A Taiwanese user has this blog and he uses it a lot: https://blog.xuite.net/chenweizong/wretch/87090672-Bronica+ZENZANON+MC+40mm+f4

The other lens is the Zenzanon 50mm MC F2.8. It is also a pancake design and has the same 67 filter ring. It is much smaller and lighter than the Nikkor 50mm O.C. F2.8 for Bronica. A user has this blog: https://moonriver7.wordpress.com/2011/05/09/zenza-bronica-ec的遺產-zenzanon-mc-50mm-f2-8/

Both lenses have perfect glass, with no scratches or fungus. They also have the original front and rare lens caps.

Hasselblad's Zeiss 40mm F4 weighs over 900g and is much larger. Hasselblad 50mm F4 is over 800g and also much larger.
