...and I do not like the heavy ones with aperture rings (can't remember codes) which I always understood to be designed for use in the darkroom, in the days when your taking lens became you enlarging lens.
Then there is that ring you put inside a hood or filter (again can't remember code) that connects with the aperture tab, seems almost as much effort as setting it normally.
What's the matter with me? I was on a roll with code names this morning but this afternoon they won't come to mind. looking in a book is cheating!
