It's been a while since I last updated my diary. Not that I had noting to do. It's rather opposite. Lectures, working with students and family need their time. And since I started to use 5x4 camera almost exclusively the development of film became the bottleneck. I promise, that I'll be a good boy and update diary on more constant basis.... For now, a comparison between "super sharp" Rodenstock APO Ronar 300mm and "soft and fuzzy" Hermagis Eidoscope #3 275mm.
