EXACTLY..... But why the reversed lens for 35mm? My experience is to shoot a Z-I and any other Zone I feel I may need on each roll of film and measure that/those entire negs. Does the reversed lens allow you to pick out a small area of the 35 neg to measure?
The reversed lens allows me to get closer to the negative. Otherwise external light may effect the readings. I also have a rear lens cap on it with a hole to prevent flare. The only reason I used a 50mm lens from a 35mm camera is that the size of the filter (49mm) is easy to couple to the lightmeter's threaded ring. I use this on 35mm, 120, 4X5 film....
