wow ,100 dollars , not head and arm. I think I must start from the body. Lens costs other 200 dollars but camera would be excellent. my sister is at dc , she can buy me. Thank you wilmarco.

Thank you Wilmarco , if mamiya 50mm have shutter , I will decrease the size of the camera. I dont want to carry 5 kilograms of camera on my neck. I have mamiya rb67 back and can make a plywood box and attach the lens. Do that lens fire itself without need of cocking by the camera body ?

I am thinking a design inspired by anamorphic pinhole camera. Due to pinhole slow shutter times and making the images real sharp , I thought I can attach an lens to the place of pinhole. But lens must have an shutter and I dont want to pay for zeiss. What are my options ? Umut I bet dan fromm will respond again as usual.

Can anyone reply on which 40mm or so mid format lens have in shutter and japanese ?

I am hoping to make my Hasselblad SWC 903 Clone and trying to find 40mm medium format cheap lens with shutter inside. I think an old Ektar, Rodenstock , Schneider or Wollensak or Dagor would be available and cheaper. But large format lenses tend to cover 4x5 or larger. My main use will be the crop 6x6cms from the frame. Do I need ultra wide angle large format lens or how I can solve the puzzle ? Mustafa Umut Sarac Istanbul

I want to build a camera like hasselblad 903 swc and I want to keep the cost to lens price only from mamiya or pentax or I dont know which . I am hoping mamiya or pentax 40 or so milimeters lenses may have shutter inside ? Is it true or false ? Thanks, Mustafa Umut Sarac Istanbul
