Nifty auction wreck for $15.00 no lens. Radioactive fungus lens from Hawaii $10.00. A little repair and major cleaning and 18 days later...both work very well thank you... oh,ah...errr, priceless?
The sort of deluxe version of the S1a, the extra features are the self-timer and a max. of 1/1000 sec. (actually the S1a had 1/1000 too, its just not printed). Both SV and S1a are the models with counter auto-reset as the predecessors S1, S2, S3.
