Sony's 2005 entry compact — 4.1MP CCD, Zeiss 3x 32-96mm zoom, AA power, full-size Memory Stick.
The Sony Cyber-shot DSC-S40 was a budget 4-megapixel compact from February 2005, part of the mid-range of Sony's entry-level S-series. The S-series traded the slimline styling of the P- and W-series for a chunkier grip and AA power, positioning cameras like the S40 as affordable first digitals for families and students.
It used a 4.1-megapixel 1/2.7-inch Super HAD CCD with a Carl Zeiss Vario-Tessar 3x zoom covering 32-96mm equivalent at f/2.8-5.1. Framing was on a 1.5-inch 77k-dot hybrid LCD. ISO spanned 80-400, exposure was automatic with seven scene modes including Twilight, Beach and Candle, and an AF illuminator helped in dim light. Video was 640x480 30fps MPEG1. Storage was full-size Memory Stick or PRO plus 32MB internal memory, and two AA cells gave a CIPA rating around 380 shots on NiMH.
Today the S40 appeals mainly as a cheap entry into mid-2000s CCD digicams — simple controls, honest colour and AA convenience in a body that shrugs off casual handling. The small dim screen and 32mm-limited wide end cap its ambitions, and with no viewfinder it is best treated as a relaxed snapshot machine.
AA power makes used ownership painless; use NiMH rechargeables rather than alkalines. It requires full-size Memory Stick or PRO cards, long out of production, so a bundled card adds real value — internal memory covers only a handful of shots. Check the lens extends smoothly, the battery door latch is intact, and the LCD is free of bleed.
