I have decided that I will keep my 503x and likely won't be using my 553 ELX (with an acute matte) and an a12 back
I therefore am offering it for sale, it is in good shape, mechanically and optically sound.
The C 100 Planar is in great shape, was just CLA'd late last year (bill available).
While I would prefer to sell it as one setup, I am also willing to split it up.
also available a 55 mm extension and a 10 mm extension tube
The Hasselblad 80 CB is also available for sale, it is in excellent shape. Times are snappy and sound accurate to me, and aperture is clean and quick.
