Thanks everybody for appreciating my efforts. I'm still struggling on how to get a good landscape shot, both in terms of framing, aperture spot and post-production technique. In particular, balancing contrast is always an interesting matter (eg: are the trees in 1 and 2 too dark?; generally speaking, how many details can get lost in pushing contrast and increasing black tones?). Anyway, the lens is the 21/2,8 Elmarit M, pre-aspherical (used without external viewfinder).
