8X30 Porlerim was introduced after WW II in 1948. Therefore this Hartmann model is not so old in design. Its best features are clear image quality and neutral colours. Its light transmission could compete very well with top brands. It also has a few interesting internal mechanical solutions. It has sharp wide field of view and is well build. Maybe a little too heavy. Excellent pair of binoculars!
