This poll is being redone by request. In the first one people ignored that I was talking in 35mm equivalents and I'm not allowed to edit my polls. This time, we're talking about the actual focal length that's written on the lens. (I'm not going to mention any thing wider than 20mm because if you check the Adapted Lens Archive, you'll see that most people are using native glass for wide situations.) So, if you must chose an adapted prime, what focal length, as is written in milometers on the lens, is your approximate favorite? Note that I'm not talking about what your favorite lens is, I'm talking about what focal length you enjoy using and think is most useful among existing adapted lenses (for example I'm sure the 75/1.8 is many people's favorite lens, but 75mm is not useful for many people so their favorite FL would be, say, 17, 25, 45, etc). Also note that if your favorite focal length is 29mm, you vote whatever is closest, which would be 28mm. Okay, I think I covered all the problems that we ran into last time. Hopefully this time it will be helpful to buyers to see what the majority prefers. Limited to one vote per person this time!
