Apo-Ronar 1:9 / 240mm

With an image circle of 212mm at f/22, I can`t use it with my 8x10, but it was my favorite lens with my Ebony 4x5"!

It is super sharp, light and one of the rare blue ring versions (latest built Ronars)!

So I will keep it, because I maybe will have a 4x5 in the future again!
