I am new to this forum, but not really hew to Hasselblad. I had a full 500cm outfit several years ago. I gave it to my son to sell so he could start his photography businees. he did and does great. This July he bought me a 500cm body in excellant condition so I am starting over again. I do have two problems-i need a new light seal for an A12 back and a +3 diopter for a waist level finder.
