I was also testing, if not experimenting, this week. Two shots, one each from cameras that I worked on recently.
First up is the Hexar AF I resurrected, as mentioned in the "I just made/fixed" thread:
And next one from the Canon VI-L I picked up in rather dubious shape (light leak, dirty, speeds off) and gave a full CLA. Lens attached for this was a Nikkor 85/2.
Both on HP5+ in Caffenol C-H(RS).
