A WIDE-ANGLE 36 mm push-on hood and a Summarit hood are 2 hard-to-find items!
David H is correct & the only easy hood option is a push on A36 series filter ring and a series filter wide angle hood, & this would help the filter availability as well.

The lens should perform well f/8 and smaller, it is pushing it to use 5.6 if you want poster size prints, but if you just want 10x8 it is ok...
