My question to those of you who have a lens of this type. What f stop have you found to be the sweet spot? I am suspecting, by my informal tests on the lens in its present condition that its optimal f stop would be f4 to f5.6. I intend to use this as I like its collapsible nature when light is sufficient for stopping the lens down. gck
