At least 2 versions of the budget Sokol were prepared by LOMO in 1973-1974. Lomo-130AL was never produced in series, while small quantity of Lomo-130A was for sale on the domestic market. These cameras have only one light meter cell and, in a clear effort to cut the most dramatic costs, lacked the strap lugs.
