I shot today trying to get the hang of Zone Shooting, and I used my Carl Zeiss Flektogon which is 35mm and F2.4.. and it has what I like to say "Character". With fast moving pedestrians (like lunchtime in NYC) it's very hard to get the hang of.. and I don't have 100% faith in the system yet. However, when folks are sitting stationary and their faces are somewhat static, it's more usable- at least to me. I choose a park path, with benches on both sides, and judged approximately where the face/eyes would be, shot at F8.. which was around 1/125th sec at ISO 200. Then- I could "work" both sides of the path and had good results. It also works when benches are on one side as well. I'm now shooting with the Carl Zeiss Jena Fektogon (35mm) and the Carl Zeiss Jena Pancolor (50mm) and will look to get an CZJ 85mm down the road. The reason is- I love the character and beautiful bokeh these lenses infuse to my images. Don't get me wrong.. my Panny/Leica 25mm 1.4 is the workhorse, but these new classics have a lot going for them!
