Proves what I have long thought....that there is much to be said for old relatively slow lenses. I guess because they did not tax the designers' skills so much in days when lens computation was still done manually. And of course they tend to be quite low contrast due to the coatings then available, which is a useful characteristic with digital imaging.
In any event I like very much the colors and tones in this image. And in fact all images in this thread exhibit similar characteristics.
Another example that springs to mind is the old auto-Takumar 55mm f2.2 which also produces some pleasant images.
