<p>Hello, all<br> I'm using a Mamiya 645AFD with a Mamiya DM22 digiback and I love the system. I have two lenses; Mamiya 35mm and Mamiya 645 80mm/2.8. The 80mm is auto only, and it's constantly focusing, making repositioning impossible. <br> I'd love some suggestions on a similar lens (maybe down to 50mm) that will allow manual and autofocus. <br> Thanks for the help, <br> s</p>
