Nezat\u00ed\u017e\u00ed tak va\u0161i fotobra\u0161nu a nepronesou se ani p\u0159i del\u0161\u00ed vych\u00e1zce. A cena? Na to, jak\u00e9 mo\u017enosti tyto objektivy fotografovi otev\u00edraj\u00ed, bych \u0159ekl velmi p\u0159\u00edzniv\u00e1 – kvalitn\u00ed 50mm objektivy se daj\u00ed sehnat ji\u017e kolem 4 000 K\u010d<\/strong>.<\/p>\n
