The Sony α 290 (DSLR-A290) is Sony's entry-level digital single-lens reflex camera (DSLR). The 14.0 megapixel α290 is available in the United States in two kit versions, one with a DT 18-55mm SAM (smooth-autofocus-motor) Sony lens and the other with the same DT 18-55mm SAM lens and a DT 55-200mm SAM Sony lens. The Sony α290 has a 9-point AF system and takes all Sony α/Minolta AF mount lenses. The 14.0 megapixel APS-C (23.5 mm × 15.7 mm) sized CCD sensor has a max ISO of 3200, however when using ISO 800 the photos start to get noisy and 1600 and 3200 have very bad noise. The Sony α290 has a BIONZ image processor and can take approximately 2.5 frames per second. The Sony α290 includes Creative Style, or preset color settings; BRAVIA Sync with a built in HDMI plug, and anti-dust technology. The Sony α290's anti-dust system is a charge protection coating on a low pass filter and image-sensor shift mechanism. The α290 also features Sony's SteadyShot INSIDE in-body stabilization.〔(C|Net Review of the Sony α230 )〕 The Sony α290 takes the Sony NP-FH50 rechargeable battery and can take about 500 photos on a full charge (according to Sony). The viewfinder on the Sony α290 has a 95% field of view and has .83x magnification (with a 50 mm lens at infinity) is arguably superior to its sister, the Sony α390, which is almost the same camera except its bigger-tilt screen and live preview. A disadvantage to the Sony α290 is its proprietary hot shoe, or where an external flash unit attaches. The Sony α290, like all other Sony Alpha DSLRs, has the iISO flash shoe. The Sony α290 officially succeeded the Sony α 230, and brought about the return of several features. It also includes a new "HELP" system, to assist new users. Like the α230, the α290 will take both a Memory Stick PRO Duo or an SD/SDHC card. The camera weighs approximately without the battery, memory card, lens and other accessories and has the approximate dimensions of 128 mm × 97 mm × 86 mm (W/H/D). The Sony α290 has a standard USB 2.0 port along with its mini HDMI port. The camera sends a review image to HDMI output immediately after taking a photo. There is no need to switch to playback mode to review. The flash on the α290 is a standard pop-up with a recycling time of approximately 4 seconds. The hot shoe is, like most other Sony Alpha camera, a proprietary iISO.〔(Sony-Style: Sony α230 single lens kit Specs )〕 The Sony α290 has a capability to work with infrared remote control and also wired remote. Remote control is sold separately, and is enabled through the Drive mode menu by selecting 'Remote Commander'. The Sony α290 has a capability to take power from AC Power Supply, model AC-PW10AM. This power supply is sold separately. ==References== http://mhohner.de/sony-minolta/onebody/a290 http://www.letsgodigital.org/en/26318/sony-alpha-290/ 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sony Alpha 290」の詳細全文を読む スポンサード リンク
